GENETIC PARAMETERS OF EARLINESS AND OTHER AGRONOMIC CHARACTERS IN TEN BREAD WHEAT CROSSES
M.
Aglan
Ten bread wheat crosses derived form five different genotypes were sown to estimate potance ratio, inbreeding depression, heritability, genetic advance and correlation coefficient, among eight earliness and agronomic characters such as days to heading, days to maturity, Grain filling period, Grain filling rate, Number of spikes/plant, Number of kernels /spike, 100-Kernel weight and Grain yield per plant. The experiment was carried out from 2009/2010 to 2011/2012 seasons at Sakha Agric. Res. Station, ARC, Egypt. The t-test of differences between parents of each cross was significant in most studied crosses. The genetic analysis showed that genetic variance among F2 plants was genetically different for all studied characters in the ten crosses. Moreover, values of potence ratios were more than unity for most studied characters in all crosses. For inbreeding depression, estimates were significant or highly significant negative for most characters in most crosses except for kernel weight which was positive for most crosses. The obtained results indicated that heritability in broad sense (h2b) ranged from moderate to high for most studied characters. With regard to expected genetic advance, values for most studied characters were moderate in all studied characters. Also, significant positive correlation coefficients among most studied characters in all crosses were detected. The best crosses for improving earliness characters were Gem. 9 × L. 2, Sh. 1 × L. 2 and L.2 × L.3. On the other hand, the favorable crosses for increasing yield and yield components characters were Gem. 9 × Sh. 1, Gem. 9 × L. 1 and Sh. 1 × L. 3. These crosses may be used in breeding program for developing characters under study.

Egyptian clover or berseem (Trifolium alexandrinum L.) is the principle forage crop in Egypt. Unfortunately, the uncertified and uncontrolled local seeds are being contaminated with dodder (Cuscuta spp.) seeds, which affecting negatively both productivity and quality of produced forage. Three field experiments were carried out at Sakha Agricultural Research Station Farm, Kafer El-Sheikh Governorate, ARC, Egypt, during three successive winter seasons; 2008/09, 2009/10 and 2010/11, to investigate the performance of 100 berseem genotypes; 96 farmers seed lots and four commercial cultivars for its resistance/tolerance to dodder infestation. Highly significant differences were observed among the 100 genotypes under evaluation as well as the interaction between the sets and genotypes for all cuts and seasonal yield in the 1st season. The commercial cultivar; Helali (Genotype no.111) has high potential and high-yielding ability in comparison with other cultivars and landraces. It was bred for relatively high ability to rapid re-growth which may be associated with tolerance to biotic and abiotic stresses. In addition to, some landraces retained the least reduction percent of total chlorophyll. In general, the berseem genotypes under investigation manifested highly significant differences at all cuts and seasonal fresh and dry yield as well as chlorophyll content for reduction percent due to dodder infestation.

Three field experiments were carried out at Sakha Agricultural Research Station Farm, Kafer El-Sheikh Governorate, ARC, Egypt, during three successive winter seasons of 2008/09, 2009/10 and 2010/11, to investigate the performance of some egyption clover genotype for its resistance/tolerance to dodder infestation. Anatomical structures as well as biochemical analyses for berseem plants werecarried out toidentify variation inthe correlated traits with tolerance to dodder infestation. The results indicated that genotypes no. 35 and 65 showed that the moderate genotypes behaved different, the parasite is scarcely able to pierce the epidermis but lignifications of host pericycle and starch sheath showed incompatible interaction between clover genotypes and C. planiflora. The sensitive genotypes no. 29 and 94 were in contrast compatible with the parasite, the infection developed normally with the intrusive cells reaching the center cylinder and the host vascular tissues.
The results indicated that the amount of phenolic acids is relatively high; 1111.65 and 965.24 mg/100 mg of foliage dry weight for genotypes; Helali and no. 51, respectively. These two genotypes could retain some tolerance to the infestation with C. planiflora. Whereas, the phenolic acids in the genotypes no. 35 and 74 which are considered to some extent retain moderate tolerance to infestation with dodder were present in lesser concentration (784.6 and 735.38 mg/100 mg). While, Genotypes no. 94 and 29 which could be considered susceptible to infestation with dodder, phenolic acids were found in trace amounts (386.64 and 423.02 mg/100 mg), respectively. HPLC analysis revealed the presence of protocatechuic acid, caffeic acid, P-hydroxyl benzoic acid, coumaric acid, ferulic acid, vanllic acid and syringic acid and their concentrations were different from berseem genotype to another.
The obtained results may be encouraging to use the tolerant genotypes, which had the least reduction percentages due to dodder infestation, for developing compost or synthetic cultivar(s) which retain tolerance to dodder infestation. This cultivar could be used by itself as a way of control of dodder in farmers' fields or integrated with the other factors of dodder control.

Field and laboratory experiments were carried out at the Farm of El-Gemmeza Agricultural Research Station, Gharbia Governorate and Seed Technology Research Department, ARC, Egypt, during 2010/2011and 2011/2012 seasons to identify and discriminate ten faba bean genotypes using morphological characters and molecular marker. The results revealed that some morphological characters such as pinnul shape, lines density of flag flower, pod color at maturity, testa shape and color were useful to identify some genotypes from each other, while they were not enough for identifying other genotypes. By using Inter-simple sequence repeat (ISSR-PCR) technique, it was possible to determine the genetic diversity and relationships of the ten faba bean genotypes included in this study. A total of 71 amplified bands were generated with five ISSR primers, of which 59 (83.1%) were polymorphic which represent a relatively high polymorphism level. These results are important in protecting of plant breeders rights and at releasing these genotypes as a new varieties.

Two field experiments were carried out during summer seasons of 2010 and 2011 at the Experimental Farm at El-Kassaien, Hort. Res. Station Ismalia Governorate, Egypt, to study the effect of sowing dates and plant density on vegetative growth, dry seed yield and its components as well as chemical constituents of dry seed for snap bean plants cv. Nebrasica grown in the newly reclaimed sandy soil. This experiment included 12 treatments, which were the combinations between three sowing dates ( February 1st , March 1st and April 1st ) and four plant density ( 56 plants/m2, 40 plants/m2 , 28 plants/m2 and 20 plants/m2). . Planting of snap been on March 1st gave the maximum values of Vegetative characters, dry weight of different plant organs at different stages of samples, seed yield /m2 and total seed yield /fed. in the two seasons. Plant density at 20 plants / m2 had significant effect on vegetative characters, total dry weight / plant at 45 and 60 days after planting in both seasons as well as 100 seeds weight , seed yield/ plant. On other hand, yield of seeds per m2 and per fed. were significantly increased by planting at 56 plants/m2 in both seasons. The interaction between sowing date on March 1st and plant density at 20 plants/m2 significantly increased total dry weight/ plant at 45 and 60 days and exhibited the highest values of 100 seeds weight and seed yield/ plant. On the other hand, the highest values of total dry seed yield per square meter and per feddan were recorded with the interaction between planting on 1st March and planting at 56 plants/ m2.

Two field experiments were conducted during 2011and2012season at Gemmeza Research Station,El Gharbia Governorate,Egypt,to study the effect of two winter crops(pure stands of fodder beet and Lentil in addition to their mixed cropping) on two successive summer crops of sunflower and maize. The first experiment was initiated in 2010/2011 winter season and terminated in 2011 the summer season whereas; initiation and termination of the second experiment were winter and summer seasons of 2011/2012,respectively.
The experimental design was split-plots design with three replication, where the preceding winter crops (fodder beet, mixed fodder beet +lentil and lentil) comprised the main plots (Both sunflower (Sakha 53 cv.) and maize (Giza 310 Cv.) were sown following the two winter crops as a relay crop into pure fodder beet (S1) and mixed fodder beet and lentil (S2) after lentils removal in addition after lentils as a double crop (S3)) and three nitrogen levels (N1=90, N2=105 and N3=120 kg N/feddan) were tried in a sub-plot. Each sub-plot was 24 m2 in area, consisting of 5 ridges (each, 4 m long and 1.2 m wide).
Results were summarized as follows;
1-All the traits of sunflower were significantly affected by preceding winter crops in both seasons,except,plant height and No. of leaves/plant in both seasons.
2-All characters of maize were significantly affected by preceding winter crops and nitrogen levels in both seasons,expect, ear leaf area in both seasons .
3-The interaction between preceding crops and nitrogen levels had insignificant effect on all traits of sunflower and maize in both seasons.
4-The highest values of Land equivalent ratio(LER)were 1.405 and 1.472 in the two seasons,respectively,with preceding crops.
5-The highest values ofArea time equivalent ratio(ATER) were ( 1.306 and 1.343) in the two seasons,respectively, with preceding crops.
6- The highest values of Relative crowding coefficient(RCC) were(6.76 and 7.79) in the two seasons,respectively, with preceding crops.

This work was carried out in private farm at kaffer saker, sharkia governorate, during the period between 2009 and 2010 seasons to study the effect of some natural supplementation type to the rice straw substrate on the growth, yield and its components, physical characters and chemical constituents of oyster mushroom fruit bodies.
The obtained results showed that, the highest values of cap diameter, cap weight and stipe weight were obtained when cultivated oyster mushroom on rice straw plus wheat grains powder at 5% followed by rice straw substrate plus faba bean powder at 5%. In addition, the highest values of early yield were recorded in case of using cowpea powder at 15% while, total yield per bag and biological efficiency % were obtained when cultivated mushroom on rice straw substrate plus cotton seed powder at 10%. However, cultivation of mushroom on rice straw substrate plus soy bean powder at 15% gave the highest values of total nitrogen, crude protein, phosphorus and potassium percentages as well as total carbohydrates.
Cultivation oyster mushroom on rice straw substrate plus cowpea powder at 15% gave the maximum values of dry matter percentage and protein yield per bag.
On the contrary, cultivation oyster mushroom on sole rice straw produced the lowest values of all studied characters.

Two field experiments were carried out during the two successive seasons of 2012/2013 and 2013/2014 at the Horticulture Research Farm of El-Bramoon, El-Dakahlia Governorate,, to investigate the response of globe artichoke plants cv. French, to foliar spray with seaweeds extract, chitozan levels and their combination on growth, earliness, quality, and productivity.
The main results can be summarized as follows:
1). The results indicated that increasing seaweeds extract and chitozan levels individual or in combination were accompanied with significant increases in vegetative growth characters (plant height, number and dry weight of leaves/ plant) and yield distribution (early, medium and late yields) compared with control.
2). Application of seaweeds extract, chitozan levels and their combination improved most head quality characteristics (head weight, diameter, receptacle fresh and dry weight as well as TSS). However, there were no significant differences in terms of head length in the two seasons.
3) Dry receptacle N, P, K, protein and total sugars contents were positively and significantly responded to application of seaweeds extract, chitozan levels and their combination in the two seasons, while inulin was affected in the second season only.
The combination between chitozan 2ml/Land seaweeds 2g/L as foliar application, seemed to be the most effective treatment, which gave a balanced vegetative growth, a higher early and total yield as well as a good quality. Moreover, this particular treatment combination was more beneficial compared to all other treatments.

Two field experiments were conducted at the Experimental and Agric. Res. Center, Fac. of Agric., Mansoura University during the two growing seasons 2012/2013 and 2013/2014 aiming at testing the possibility of partly replacing the costly and hazardous chemical fertilizers with less costly and environment friendly organic and bio-fertilizers to satisfy the fertilizer requirements of Sweet basil (Ocimum basilicum) plants. Results indicated that organic and bio-fertilizers compensated for the omitted chemical fertilizers. With omission of half dose of chemical fertilizers, the best herb fresh and dry as well as essential oil yield were obtained when farmyard manure (FYM) at 30m3/fed was combined with the mixture of effective microorganisms (EM) bio-fertilizer. Essential oil quality was maximum under the fertilizer regime which combined FYM at 30m3/fed with microbein and half dose of the chemical fertilizer where linalool and methylchavicol percents were maximum. Based on the obtained results, it could be concluded that half dose of the chemical fertilizers requirements of sweet basil plants could be replaced by 30m3/fed FYM, preferably, in combination with EM bio-fertilizers to reduce production costs and at the same time maintain herb and essential oil yield as well as enhance essential oil quality.

The present study was carried out during the five seasons 2008/09, 2009/10, 2010/11, 2011/12 and 2012/13 at Sakha Agricultural Research Station, Kafr El-Sheikh governorate, Egypt. The study aimed at evaluating the effectiveness of pedigree, bulk (natural selection), single pod descent (SPD) and mass selection breeding methods on improving faba bean seed yield and resistance to foliar diseases i.e,chocolate spot Botrytis fabae and rust Uromyces fabae .
Three F2 populations derived from three crosses were used. Ten pure lines derived from each of the four breeding methods in each cross were tested for days to maturity, seed yield (ardab/fed.), reaction to chocolate spot and rust disases in a randomized complete block design with three replications. Significant seed yield differences existed within F6 pure lines of each cross by applying each of the four methods.
Both cross-progenies and breeding methods squares were highly significant for all studied traits. The interaction of cross-progenies by breeding methods mean squares was highly significant for all studied traits and also the interaction of cross progenies by pure lines, breeding methods by pure lines and the second order interaction of cross-progenies by breeding method by pure lines were highly significant for seed yield (ardab/fed.) while the same interactions was not significant for the other traits i.e., days to maturity and reactions to chocolate spot and rust. The cross-progeny; Sakha 2 x TW was the earliest in maturity when bulk method was applied, while the cross-progeny; Sakha 1 x RM had the highest seed yield with the pedigree method and the cross-progeny; R.M. x Giza 3 was more resistant to both chocolate spot and rust under the breeding method of single pod descent.
Pedigree method recorded its superiority than the other breeding methods with respect to broad sense heritability and subsequently expected and predicted genetic advance in the cross-progenies; Sakha 1 x Rina Mora and Rina Mora x Giza 3 for seed yield/fed. While in the cross progeny; Sakha 2 x TW, the breeding method of single pod descent had the highest broad sense heritability, expected and predicted genetic gain upon selection of the highest 20% plants in the population for the same trait.
It could be concluded that the pedigree and SPD methods were more efficient and could be less expensive in breeding for improving seed yield and foliardiseases (chocolate spot and rust) resistance of faba bean.

EFFECT OF SOME PLANT DENSITIES PATTERNS AND NITROGEN FERTILIZER RATES ON COTTON YIELD, ITS COMPONENTS AND FIBRE PROPERTIES FOR HYBRID COTTON 10229 X GIZA 86 UNDER EARLY AND LATE SOWING
Amal
Abd El-Aal
Four field experiments were conducted at Sakha Agriculture Research Station, Kafr El-Sheikh Governorate during 2011 and 2012 seasons. Early and late sowing experiemnts were carried out in the first season and repeated in the second season. These experiments were conducted to study the response of hybrid cotton 10229 x Giza 86 to agricultural systems, i.e., 43077 plants/fed. (65 cm ridge width and 30 cm hill spacing on one side), 36923 plants/fed. (65 cm ridge width and 35 cm hill spacing on one side), 48000 plants/fed. – (100 cm ridge width and 35 cm hill spacing on two sides) and 42000 plants/fed. (100 cm ridge width and 40 cm hill spacing on two sides) and nitrogen levels of 45, 60 and 75 kg/fed. Plants were thinned to two plants per hill after the formation of the second true leaf. Two of these experiments were carried out for the early sowing (15 April), but the other two experiments for the late sowing (15 May). The treatments carried out in the early planting also applied in the late sowing. The results can be summarized as follow:
1. Increasing plant population density significantly increased final plant height, number of monopodia, number of sympodia per plant, number of main stem internodes/plant, nodal position of first sympodium, shedding percentage, number of open bolls and unopen bolls/plant, boll weight and seed cotton yield (kentar/fed.) in the two seasons. However, earliness percentage and percentage of plant losses/fed. significantly decreased by increasing plant density.
2. There were significant differences among the three nitrogen levels, in all growth, earliness characters and yield and its components. Application of 75 kg N/fad. produced the highest values of plant height, number of monopodia and sympodia/plant, number of main stem internodes/plant, nodal position of the first sympodium, number of open and unopen bolls, boll weight and seed cotton yield (kentar/fed.), while the lowest nitrogen level (45 kg N/fed.) produced the lowest values of earliness %, shedding % and stand losses % at harvest. Seed index, lint percentage and fiber properties insignificantly affected by all treatments. The interaction between agricultural systems and nitrogen levels attained insignificant effect on all traits.
3. The results showed that late sowing took the same direction as early planting and were higher values for the number of bolls, boll weight, yield and its components.
In general, it can be stated that early sowing (15 April) of hybrid cotton 10229 x Giza 86 with 75 kg N/fed. and higher density 48000 plants/fed (100 cm ridge width and 35 cm hill spacing on two sides) induced higher seed cotton yield.

EL-Sherbini
Two field experiments were conducted at Private Farm in EL-Salheya, SharKia Governorate, Egypt during winter seasons of 2012/2013 and 2013/2014 to study the effect of plant density and some foliar applications, i.e., moringa leaf extract (MLE), chitosan at 150 ppm and silicon at 200 ppm on vegetative growth, pod yield and quality of snow pea cultivars, i.e. “Compados and Snow Wind” and sugar snap pea cultivar “Sugar Snap”.
The results showed that Compados cultivar had more leaves and branches, longest plant height, heaviest fresh and dry weight, largest leaf area, and gave the highest pod length and pod yield (ton/fed.) compared with other cultivars in the two seasons. Whereas, the least one was Sugar Snap cultivar in both seasons. Moreover, Sugar Snap cultivar was the highest in pod thickness, total soluble solids (TSS) and carbohydrates (%) and the lowest in titrable acidity (%) in both seasons. While, Snow Wind was the superior in vitamin C (mg/100g fw) in both seasons. Meanwhile, plant density (20 cm apart) gave the highest plants and total pod yield/fed. compare with other densities (40 and 60 cm) at the two seasons whereas, (60 cm apart) gave the highest values in all studied parameters except plant height and total pod yield/fed followed by (40 cm apart plants) in both seasons. All foliar applications significantly increased all the studied parameters compared to the control treatment. The superior application was moringa leaf extract (MLE) followed by chitosan and silicon in both seasons, respectively.
From the obtained results it could be concluded that Compados cultivar was the highest pod yield/plant, and total yield/fed. when cultivated on 20 cm apart, meanwhile Sugar Snap cultivar gave the best pod quality when cultivated on 60 cm apart and sprayed with moringa leaf extract three times, i.e., 15 days after planting then repeated each 15 days interval, respectively.

This study was conducted during two successive seasons (2012 and 2013) to evaluate the effect of Carboxy Methyl Cellulose (CMC), Cellulose and beeswax at concentrations of 2 and 3% as edible coatings on some "Murcott tangor"fruit quality parameters. The coated and control(uncoated) fruits were stored under cold storage conditions (5±1˚C and 90-95% RH) and for 7 days at ambientconditions after every cold storage period. The variousphysiochemical attributes of fruits were recorded after 0, 20, 40, 60 days in cold storage and after 7 days at ambientconditions of every cold storage period. Fruit weight loss (%), SSC (˚Brix), SSC/acid ratio, total carotenoid (in peel) and pectic substances (in peel and edible portion) of Murcott tangorfruits were increased in most cases; whereas, titratable acidity (%), V.C (mg/100g) and juice ratio were decreased with advancing the storage period.However, the results of the study indicated that Murcott tangor fruits coated with Carboxy Methyl Cellulose showed a significant deterioration delay in the different determined parameters of Murcott tangor fruits either at cold storage or ambient condition. Fruits coated with Carboxy Methyl Cellulose (especially at 3%) can be successfully stored for 60 days under cold storage conditions and for 7 days at ambient condition after cold storage with highly acceptable sensory quality.

EFFECT OF SKIPPING IRRIGATION AT VARIOUS GROWTH STAGES ON YIELD AND QUALITY OF SOME FABA BEAN CULTIVARS (Vicia faba L.)
M.
Mekkei
Two field experiments were conducted at Agric. Exp. Res. Sta., Fac. Agric., Cairo Univ., during 2011/2012 and 2012/2013 seasons to study the effect of five irrigation treatments (I1; normal irrigation "control" ; I2: skipping the second irrigation ; I3: skipping the third irrigation; I4: skipping the fourth irrigation and I5: skipping the fifth irrigation) on yield and seed quality of three cultivars of faba bean (Giza 3, Nubaria 1 and Sakha 3 ). A spilt plot design in a randomized complete blocks arrangement with three replications was used to conduct all trials. Irrigation treatments were randomly assigned for main plots while, faba bean cultivars were randomly arranged for sub plots. Results showed that skipping irrigation at various growth stages had significant effect on all studied traits in both seasons. Skipping the fourth or the fifth irrigation gave the greatest reduction in all yield traits except, seed protein content which increased in both seasons compared with other irrigation treatments. Regarding faba bean cultivars, differences among the three faba bean cultivars were significant except, number of pods plant-1, pods weight-1, number of seeds pod-1 and harvest index (%) in both seasons. Giza 3 cultivar gave the highest values all yield traits and seed protein content (%) followed by Nubaria 1. However, Sakha 3 cultivar gave the lowest value of all yield traits and seed protein content (%) in both seasons. For interaction between irrigation regime and faba bean cultivars, all faba bean cultivars were affected by skipping irrigation in both seasons. Giza 3 cultivars was more tolerant to skipping irrigation followed by Nubaria 1 however, Sakha 3 was more sensitive to drought stress.

Some selection procedures i.e. selection index involving 11 indices and direct selection for four separately traits (lint yield/plant, bolls/plant, seeds/boll and lint/seed) were used to improve lint yield, yield components and fiber properties in early segregating generations; F2, F3 and F4 of the cotton cross;(Giza 85 x Dandara). Means of F4 generation were higher than those ofF2and F3 generations for all studied characters except for fiber fineness (desirable)and fiber length .The heritability estimates obtained in F2,F3 and F4 generations were ranged from moderate to high (56.18 to 92.2%) for most traits. These estimates indicate a possible success in the selection of the early generations that were evaluated . Estimates of PCV and GCV in F4 for most traits were higher than those of F2 and F3 generations. It was due to the application of several procedures that having various performance in selection. Phenotypic variances (Vp) were found to be greater than the corresponding genotypic variances (Vg) for all studied characters indicating that the expressions of these characters were influenced by the environmental factors.
Deviations of the realized advance from the predicted of lint yield determined in F3 to F4 generations were positive and high for most selection procedures. Data showed that indices; I.w1, I.w2 , I.w123 ,I.w12 , I.w23 , I.w13, I.w3 and I.xw gives high value of improvement in lint yield as predicted and actual advance . However, The data also indicated that predicted advance from F3 had high value of gains relative to actual advance for most indices . Also, the gains were higher in F3 and F4 than those F2 generation. This may be attributed to the efficiency of selection procedures application in this study. After two cycles of selection, the genetic gains from selection isolated it isolation best ten families on base of the highest value in selected and unselected traits; it my be very important in cotton improvement programs .

In order to evaluate nutritive value of some Egyptian clover varieties two field experiments were carried out at the Experimental Research ٍStation, Faculty of Agriculture at Moshtohor, Benha University during the two growing seasons of 2010/2011 and 2011/2012. Chemical constituents potentialities of five Egyptian clover (Trifolium alexandrinum, L.) varieties i.e.Gemiza 1, Sakha 4, Helali, Giza 6 and Serw 1 under various phosphorus fertilization levels i.e.0, 22.5 and 45 kg P2O5/fed were investigated chemical analysis was conducted for the second and fourth cuts of each of the two growing seasons for the different grown varieties. Combined analysis of the two seasons was done after insuring the validity of partlet test (Steel and Torrie, 1981).Results could be concluded as follows:
Results of the combined analysis of the two seasons indicated significant differences in crude protein (CP), crude fiber (CF), Ash, ether extract (EE), nitrogen free extract (NFE), total digestible nutrients (TDN) and digestible protein (DP%) among the studied five Egyptian clover varieties during two cuts. Highest content of CP, CF, P, DP and TDN% were obtained for Gemiza1, whereas, Helali variety recorded highest content of Ash and EE% with significant differences of different magnitudes. Also, highest NFE content was recorded for Giza 6.
Results showed that CP, CF, Ash, EE, P, DP and TDN % were substantially increased as phosphorus fertilization levels increased from 0 to 22.5 and up to 45 kg P2O5 /fed. However, reverse trend was observed for NFE content.
It could be concluded that highest forage quality of Egyptian clover was produced from sown Gemiza 1 variety and fertilizing with 45 kg P2O5/fed.under North Delta conditions.

The field work was carried out at the Experimental Farm of Horticultural Research Station in El-Quassassin, Ismailia Governorate, Egypt, during the two successive seasons of 2009-2011 and 2010-2012, to investigate the effect of drip irrigation treatments (1, 2 and 3 times/week, 2 hours every time) and fertilization treatments (ammonium sulphate (20.5 N %) at 300 kg/fed., calcium superphosphate (15.5 P2O5 %) at 300 kg/fed. and potassium sulphate (48 K2O %) at 100 kg/fed., humic acid at 280 g/fed., effective microorganisms (EM1) at 5 liters/fed. and active dry yeast at 6 g/L.) and their interactions on the vegetative growth parameters (plant height, number of branches and fresh weight of herb/plant), yield of herb (fresh herb yield/fed./cut and fresh herb yield/fed./year), essential oil contents (essential oil percentage, content(ml.)/plant, oil yield (L.)/fed./cut and oil yield (L.)/fed./year) and the chemical compositions (N, P, K and carbohydrates %) of Pelargonium graveolens L. plant.
The results showed that, the treatment of irrigation 3 times every week gave the highest values of all vegetative growth parameters, essential oil contents and chemical composition (N, P and carbohydrates %) followed by 2 times/week, during 4 cuts in the two seasons. Fertilizing with recommended NPK gave the highest results of all vegetative growth parameters, yield of herb, essential oil contents and chemical composition (N, P and K %), followed by humic acid, throughout the four cuts in both seasons. The combined treatment of irrigation 3 times/week + NPK resulted in the highest values of vegetative growth parameters, yield of herb, essential oil contents and chemical composition (N, P and carbohydrates %) followed by the interaction treatment of irrigation 3 times/week + humic acid fertilizer, during 4 cuts in the two seasons. From the results of this study, we observed that, the highest values of vegetative growth parameters, herb yield, essential oil contents obtained in the third cut followed by the fourth cut in the second year of season, while the least results found in the first and second cuts, in the first year of season, these findings repeated in the two seasons.
