In general, plants fertilized with sulphur elemental were better than unfertilized plants. Increasing of applied sulphur level from 150 to 450 kg S/fed significantly improved all studied growth characteristics, yield and its components in addition to chemical constituents, bulbing ratio and number of cloves/bulb which had a better values in both seasons. Moreover, sulphur application at 450 kg/fed significantly increased concentrations of N, P, K, S, TSS % and volatile oils in cloves and enhanced storability. Foliar spray garlic plants 3 times past 45 , 60 and 75 days from planting with chitosan (200 mg/L) exceeded other foliar spray with some natural stimulants and formed the highest means of whole studied growth characteristics, yield and its components, chemical constituents and enhanced bulbing ratio, number of cloves/bulb storability in both seasons. The best results were obtained by application of 450 kg S/fed and foliar spray with chitosan. This treatment achieved reduces weight loss at the end of the storage period reached to 20.3% and 20.5% in the first and the second seasons respectively comparing with the untreated ones. Therefore, this treatment could be recommended for raising garlic yield and improving bulb quality during the storage period under similar conditions to this work.

Station, ARC, throughout 2015/16 and 2016/17 seasons, to investigate the performance of two pea cultivars (Master-B and Balmoral)receiving different weed control treatments (Amex 48% EC rate 1.25 l/fed pre-emergence, Stomp 45.5% CS at 1.7 L/fed pre-emergence, hand hoeing once at 20 days after sowing (DAS)+ Select super EC 12.5 at 500 cm<sup>3</sup>/fed, hand weeding once at 20 DAS + Bazagran at 500 cm<sup>3</sup>/fed at 40 DAS, Select super + Bazagran, hand weeding two times at 20 and 40 DAS and un-weeded) on weeds, yield and its components in pea. Results revealed that dry weight of grassy and broad-leaved weeds (g/m<sup>2</sup>) was decreased in each cultivar when applying the different weeding treatments. Cultivars of pea considerably influenced each of growth traits, yield and its attributes in each season. Pea cultivar of Balmoral decreased dry weight of weeds (g/m<sup>2</sup>) and significantly raised plant height, branches number per plant, pod dimension, number of ovules/pod, shell-out%, seed index, green pod yield (ton/fed) and dry seeds yield (kg/fed) relative to pea cultivar of Master-B in the first and second season. Using hand weeding two times at 20, 45 (DAS), hand weeding once at 20 DAS with any of Select or Bazagran at 500 cm<sup>3</sup>/fed+Select super gave more decline of the dry weight of tested weeds (g/m<sup>2</sup>) in each season. Hand weeding two times, hand hoeing once with any of Select super or Bazagran increased significantly all growth and yield attributes. The impact of interactions between cultivars of pea and weed control strategies were statistically significant effect, as by cultivating Balmoral cultivar using two times of hand hoeing or one time of hand-hoeing with spraying herbicide (select super) surpassed all other treatments in the first and second season.Mansoura University, Faculty of AgricultureJournal of Plant Production2090-36699520180503Effect of Cyanobacterial Extract and Compost tea on some Growth, Flowering Parameters and Biochemical Properties of Pelargonium zonale,(L) L'Hérit plants4494583579910.21608/jpp.2018.35799ENSamia M.

Kafr El-Sheikh Univ., EgyptJournal Article20180415The effects of cyanobacterial extract and tea of the composted rice straw on some growth, flowering parameters and biochemical properties of <em>Pelargonium zonale</em> plants were investigated. As soil drench and foliar spraying, treatments were applied in pots trial during two successive seasons. Results indicated significant enhancements of the tested vegetative growth parameters i.e. plant height, number of branches, stem diameter, fresh and dry weights of the aerial parts due to all treatments, with relative superiority of the mix treatment as foliar spraying. Due to use the mix treatment, averages data of aerial parts dry matter during both seasons reached 19.64 % as foliar spraying and 19.42 % as soil drench compared with 10.30 % for control treatment. Similarly, root length, number of roots, fresh and dry weights of roots were also increased due to application of all treatments especially the mix treatment but as soil drench in both seasons compared with control plants. The use of the mix treatment, average data of root dry matter during the studied seasons reached 25.10 % as foliar spraying and 27.32 % as soil drench compared with 16.83 % for control treatment. So, vegetative growth parameters were increased by foliar spraying and root parameters were remarkably enhanced due to soil drench application. Moreover, all treatments tended to induce significantly increase in number of inflorescences/plant, number of florets/ inflorescence, inflorescence diameter, as well as inflorescence fresh weight, peduncle length and flowering duration. In addition, results indicated that, chlorophyll (a), chlorophyll (b) and total carbohydrates, percentages of nitrogen, phosphorus and potassium in the leaves were also significantly increased. So, application of combined treatment of cyanobacterial filtrate and compost tea, three weeks as drench soil and/or foliar spraying after transplanting of <em>Pelargonium zonale</em> plants, four times with two weeks' interval was recommended under similar experimental conditions of the presented study.Mansoura University, Faculty of AgricultureJournal of Plant Production2090-36699520180507Estimating of Stability Parameters among some Extra Long Staple Cotton Genotypes under Different Environments4594683580510.21608/jpp.2018.35805ENReham H. A.GibelyCotton Research Institute, Agricultural Research Center, Giza, Egypt.S. S.HassanCotton Research Institute, Agricultural Research Center, Giza, Egypt.Journal Article20180417Understanding the implication of genotype x environment interaction (GEI) structure is an important consideration in plant breeding programs. A significant GE interaction for a quantitative trait such as yield can seriously limit efforts in selecting superior genotypes for both new crop introduction and cultivar improving. In order to, select the best lines in Egyptian cotton breeding programme two trials must be done, the first one is preliminary trial (HA) which has sown in one location and the second one is the advanced trial or regional trial (HB) sown in the production area of Egyptian extra-long staple cotton varieties. The experimental design for the two trials was a randomized complete block design with six replications in each location and each entry was grown in plot of five rows. Forty two cotton genotypes showed highly significant differences in trial A. twenty four selected genotypes from trial A was evaluated in the regional trial (HB) and the combined analysis of variance showed highly significant differences for the genotypes, environments and G x E interaction indicating the possibility to select the most stable genotypes in trial HB across five locations. two genotypes No. 11 and 18 are stable for the three studied traits and No. 14 for seed cotton yield and lint yield are good adapted for the most important cotton production locations for extra-long staple cotton varieties using Eberhart and Russell model. The results of AMMI analysis indicated that the first two AMMI (IPCA1 and IPCA2) were highly significant. The first two multiplicative components of the interaction accounted for 58.77, 68.20 and 77.13 % of the sum of squares for boll weight, seed cotton yield and lint yield, respectively. AMMI stability value (ASV) and yield stability index (YSI) are suitable stability indices in discriminating stable genotypes with high mean yield performance. Four genotypes No. 6, 12, 14 and 17) are stable under the two phenotypic models.Mansoura University, Faculty of AgricultureJournal of Plant Production2090-36699520180509Genetic Analysis of some Quantitative Characters in Egyptian Cotton4694753580810.21608/jpp.2018.35808ENS. S.HassanCotton Research Institute, Agricultural Research Center, Giza, Egypt.Journal Article20180419 This study was carried out at Sakha Agricultural Station, ARC. during four seasons (2014 - 2017). Genetic analysis of F<sub>1</sub>, F<sub>2</sub> and F<sub>3</sub> made used to estimate the genetic variability and some genetic parameters that clarify the nature of gene action controlling inheritance of yield, its components and fiber quality of two Egyptian cotton crosses. Significant differences among the five populations (two Parents, F<sub>1</sub>, F<sub>2</sub> and F<sub>3</sub>) were detected in both crosses for most studied indicating the parental genotypes exhibited sufficient genetic variability for further genetic studies. Hybridization increased the variation in F<sub>2</sub> generation in both crosses compared with the parents for most of the studied traits indicating the effectiveness of hybridization in inducing the variabilities in the genetic materials. Among the four parents involved in this study, Giza 96 variety showed the highest values for productivity traits while Giza 93 had the best fiber quality traits. Concerning the gene effects, results indicated that the studied traits were quantitatively inherited. The additive effect (d) showed significant positive values for seed cotton yield, lint cotton yield, lint percentage, Fiber length and uniformity ratio in both crosses while the dominance effect (h) showed significant values for seed cotton yield, lint percentage, fiber strength and uniformity ratio in cross I and lint cotton yield, fiber strength and uniformity ratio in cross II . The epistatic effects showed that, Additive x additive interaction was prevalence for the inheritance of most traits while dominance x dominance interaction was less important. The results exhibited significant differences among the five generations (tow Parents, F<sub>1</sub>, F<sub>2</sub>, and F<sub>3</sub>) in both crosses for boll weigh, and lint cotton yield traits indicating that the parental genotypes exhibited genetic variability valid for further genetic studies. Hybridization increased the variability in F<sub>2</sub> generation in both crosses as compared with their parents for seed cotton yield lint, cotton yield and micronaire in cross I and seed cotton yield in cross II. The studied traits indicated the effectiveness of hybridization in inducing variabilities in the studied materials. Concerning the gene effects results indicated that the studied traits were quantitatively inherited. The additive effect (d) showed significant positive values for boll weigh, seed cotton yield , lint cotton yield, lint percentage, fiber length and uniformity ratio traits while the dominance effect (h) showed significant values for seed cotton yield, lint percentage and uniformity ratio traits and it was larger in magnitude than the additive effect effect (d) in both crosses for all studied traits except boll weight and micronaire in cross I and cross II and Fiber strength in cross II. The epistatic effects showed that, additive x additive interaction (i) was prevalence for the inheritance of seed cotton yield, lint cotton yield, lint percentage and fiber length traits in cross I and boll weight and fiber strength in cross II, while dominance x dominance interaction (I) was larger important for lint cotton yield, lint percentage, fiber length and uniformity ratio in cross I and micronaire and uniformity ratio in cross II. Broad sense heritability showed high values for uniformity ratio in cross I and boll weight and seed cotton yield in cross II while it was relatively moderate values for boll weight, seed cotton yield, lint cotton yield, lint percentage, micronaire and fiber length in cross I and lint cotton yield, lint percentage and micronaire, while heritability in narrow sense and Parent–off spring regression showed low values for lint percentage, micronaire, fiber strength, fiber length and uniformity ratio in cross I and boll weight, seed cotton yield, lint cotton yield, lint percentage and fiber strength in cross II of the studied traits. The expected genetic advance from selecting the desired 5% of the F<sub>2</sub> showed high values for fiber length in cross I and cross II, while moderate values were recorded for lint percentage in both crosses, while showed low values for other traits. The results partial dominance for lint cotton yield, lint percentage, micronaire, fiber strength, fiber length and uniformity ratio in cross I and seed cotton yield, lint cotton yield, lint percentage, micronaire, fiber length and uniformity in cross II while for boll weight and seed cotton yield in cross I and boll weight fiber strength and uniformity showed over dominance. Dominance was towards the higher parent in most cases. Inbreeding depression values were positive for boll weight and micronaire in cross I and boll weight, lint percentage and micronaire, these results were in harmony with the recorded reduction in the mean performance in F<sub>2 </sub>generation. Mid-parent heterosis in F<sub>1 </sub>populations was low for lint cotton yield, lint percentage and micronaire in cross I and lint cotton yield, lint percentage, micronaire, fiber strength, fiber length and uniformity ratio in cross II. Generally the pervious results exhibited that the important the each dominance and additive effects for controlling of genetic behavior for most traits.

The important results were as follows. Analysis of variance due to line x tester and combining ability for yield and fiber quality were highly significant for most traits in both normal and water stress conditions. The variance due to general combining ability (GCA) was lower than specific combining ability (SCA) for all studied characters which, means that all traits controlled by non-additive gene action. Contribution due to line parents were greater than contribution due to testers in under stress condition. Higher values were recorded in the parental genotypes Giza 67 for seed cotton yield/plant followed by Giza 86 and Giza 94, while highest seed cotton yield/plant and lint yield were recorded by the cross combination Giza 86 x Dandra followed by Minufy x Australy, Giza 96 x Dandra and Giza 67 x PimaS6 Under normal irrigation condition. On the other hand, seed cotton and lint yield/plant were consistently affected by water deficit. Fiber quality properties were decreased in inferior direction except micronaire value, since fiber was relatively fine but it was weak and shorter under water deficit condition. Positive correlations between yield and each of its components were observed in most cases, while correlations among yield traits were higher in normal irrigation as compared with water stress. Boll weight was positive correlated with most yield components at genotypic and phenotypic levels in both normal irrigation and water stress conditions. Positive correlation in general were found between most fiber quality traits ( fiber strength (F.S), fiber length (F.L.) and fiber fineness (F.F.)) ,while it was positive between them with micronaire reading.Mansoura University, Faculty of AgricultureJournal of Plant Production2090-36699520180515Influence of Different Soil Applied Levels of (NPK) and Compost on Growth, Yield, Fruit Quality and Leaf Nutrient Content, of "Anna" Apple Cultivar Trees4854933581910.21608/jpp.2018.35819ENE. A.IsmailHorticultural Research InstituteA. M. A.Abd El-HadySoil, Water and Environment. Research Institute Agric. Res. Center, Giza, EgyptJournal Article20180426The current study was undertaken to evaluate the effects of various soil applied rates of (NPK) and compost compound either alone or in combination on some vegetative growth measurements, fruiting aspects, fruit quality and leaf nutritional status of "Anna" apple cultivar trees budded on MM106 rootstock grown at El-Kanater Experimental farm belonging to Horticultural Research Station during the two successive seasons of 2011 and 2012. Data obtained clearly indicated that, most of the (NPK) and (compost) levels either alone or in combination treatments exhibited a positive effect and a significant increment in all studied vegetative growth parameters i.e., shoot length, number of leaves per shoot and leaf surface area. Moreover, fruiting parameters (yield as kg/tree and ton per fed.) were statistically increased with increasing the levels of the most studied treatments in the two seasons of experimental study. Also, data revealed obviously that, fruit characteristics including both fruit physical properties i.e., (fruit weight, volume, firmness, length and diameter) and fruit chemical characteristics such as TSS %, total acidity % and TSS/acid ratio were significantly improved when treated trees with various treatments especially with the highest soil applied levels of NPK or/and compost when compared to the lowest level. Furthermore, leaf nutritional status of some studied nutrients i.e., nitrogen, phosphorus and potassium were generally improved and increased as a result of the different investigated treatments under this investigation from the standpoint of statistic during both seasons of study. Generally, it could be concluded that, most of (NPK) and (compost) soil applied treatments either alone or in combination resulted in a positive and a significant effect on all investigated vegetative growth, fruiting aspects and both fruit quality (properties) and leaf nutrient content of "Anna" apple trees in most cases. Furthermore, the highest level of combination treatment of (N<sub>4</sub>P<sub>4</sub>K<sub>4</sub> + compost at 2000 ml<sup>3</sup>) was the most effective treatment for increasing growth, yield, leaf nutrient contents and improving the most fruit properties.Mansoura University, Faculty of AgricultureJournal of Plant Production2090-36699520180519Studies on the Effect of Salinity and Spraying of Microelements on Vegetative Growth of some Turfgrasses4955023582810.21608/jpp.2018.35828ENA.

Damietta Univ. during two seasons of 2015-2016 and 2016-2017. The research aims to test the effect of chemical fertilizer as microelements and salinity on two species of turfgrass (paspalum and seashore paspalum). 16 treatments were arranged in split block design with 3 replicates as follows: 4 levels of salinity (control, 1800, 3600 and 7200 ppm) as main plot and 4 sources of micronutrient in foliar way (without, Fe, Mn and Zn) as sub plot. The obtained results could be summarized as follows: fresh and dry weight g/plant, moisture%, chlorophyll content, Fe, Zn and Mn content as well as protein and carbohydrates content % decreased with increasing salinity levels. However, application of micro elements improved the previous traits by causing significant increases in the values with the corresponding controls. Foliar application of iron was the most effective one. Except protein was with zinc. As for, Paspalum, found that seashore paspalum recorded higher mean values of fresh weight than paspalum. Regarding to the interaction effect found that using iron as foliar application under low level of salinity recorded the highest mean values of parameters under study.Mansoura University, Faculty of AgricultureJournal of Plant Production2090-36699520180530Evaluation Effect of Different Maintenance Systems on some Ornamental Plants in the North-Western Coast of Egypt5035073583410.21608/jpp.2018.35834ENN.
