The influence of ascorbic and salicylic acids in alleviating the adverse effects of soil salinity on growth and chemical composition of Khaya senegalensis seedlings was investigated.
Soil salinity, especially at the high level (0.7%) decreased different vegetative growth characters, namely, plant height, stem diameter , number of leaves and dry weight of leaves, stem and roots , as well as, chlorophyll a & b, carotenoids and leaves % of N, P and K. While, leaves % of Na, Ca and proline were increased due to salinity treatments. On the other side, ascorbic acid and salicylic acid, particularly, at the high concentration (200 ppm) each, improved all prementioned vegetative growth traits and leaves content of the three photosynthetic pigments and N, P and K %, meanwhile, leaves % of Na, Ca and proline were reduced. Both ascorbic acid and salicylic acid were effective in alleviating the harmful effects of salinity on growth and chemical constituents of Khaya senegalensis seedlings.

A field experiment was carried out during the two successive seasons of 2011/2012 and 2012/2013 to study the effect of compost levels (zero, 5, 10, 15 ton/fed.) and biofertilizers (effective microorganisms and active yeast), as well as, some vitamins (vitamin E and vitamin B1) and their interaction on Gladiolus grandiflorus cv. Eurovision plant.
Results showed that vegetative growth (leaf length, number of leaves/plant and dry weight of leaves/plant), flowering aspects (length of spike, number of florets/spike and lower floret diameter) and corm production (corm diameter, corm dry weight and number of cormels per plant) were gradually increased by increasing the level of compost fertilizer.All biofertilizers and vitamins treatments significantly increased all vegetative growth characters, flowering parameters and corm and cormels production in comparison with the control. Effective microorganisms and active yeast treatment seemed to be more effective than other treatments in this concern.
Their use of high level of compost (15 ton/fed.) in combination with combined biofertilizers treatment noticeably improved different vegetative growth characters, flowering parameters and corm production of gladiolus.

This study was carried out during 2012 and 2013 summer seasons at The Experimental Farm of Fac. Environ. Agric. Sci., El-Arish, North Sinai, Egypt, to study the effect of lowering the recommended phosphorus dose with foliar phosphorus addition on growth and productivity of cowpea (Vigna unguiculata L. Walp.) plants. This experiment included 7 treatments which were: The control which was the recommended rate of phosphorus fertilizer as soil addition (40kg P2O5/fed.) (T1), 100% of the recommended dose + spraying with phosphorus once weekly at rate of 2% of super phosphate (T2), 100% of the recommended dose + foliar spray twice weekly (T3), 75% of the recommended dose + foliar spray once weekly (T4), 75% of the recommended dose + foliar spray twice weekly (T5), 50% of the recommended dose + foliar spray once weekly (T6) and 50% of the recommended dose + foliar spray twice weekly (T7). Results show that application of T6 caused maximum plant height, stem length and total dry weight and differed significantly with other treatments, while T5 gave rise to maximum number of branches and leaves area per plant. Most of growth parameters were enhanced with the decrease of phosphorus soil addition and spraying with foliar phosphorus. Treatments have a significant effect on green pods yield, seeds yield, number of seeds per pod, protein %, protein yield and pod weight. Phosphorus treatments have a significant effect on weight loss % at room and cold storage conditions. Color changes as b* and c* at the case of storage at room temperature (28.5 ±5°C) were more acute after 5 days of storage than cold storage (14±1°C) conditions.

A.
Masoud
Two field experiments were carried out during the winter seasons of 2008/2009 and 2009/2010 at farm in Disuq district. Kafr El-Sheikh Governorate to investigate the effect of intercropping system between cabbage (Brunsiwek cv) and pea (Master B cv) and foliar application of boron (0, 50 and 80 ppm) and iron (0, 100 and 200 ppm) on growth, yield and yield quality as well as the economic value.
The results could be summarized as follows:
1. Intercropping pea with cabbage increased plant height, but decreased number of leaves, leaf area and plant fresh weight compared to pea solid cropping in both seasons. The highest green pod yield of intercropped pea was obtained from planting cabbage on one side and three rows of pea on the other side which gave 2.731 and 2.079 ton/fed. in the two seasons, respectively.
2. Spraying pea plants with boron at 50 ppm or iron with 200 ppm increased plant height, number of leaves, leaf area plant fresh weight, pod length, number of seeds/pod and total green pod yield in both seasons.
3. The highest yield of intercropped cabbage was obtained from planting one row of cabbage on one side and one row of pea on the other side which gave 44.31 and 40.74 ton/fed in the two seasons, respectively.
4. Spraying cabbage plants with boron at 50 ppm or iron at 100 ppm increased number and weight of inedible and edible leaves, total head weight, head yield./fed. and cabbage head quality in both seasons.
5. Intercropping pea with cabbage where cabbage grew one side and two rows of pea on the other side or cabbage in one side and three rows of pea on the other side gave high economic values. These two intercropping systems exceeded the solid planting of cabbage with 48.9 and 65.4 % in the first season, and 43.8 and 36.8% in the second one, respectively.

Two field experiments were carried out during the winter seasons of 2008/09 and 2009/10 at a private farm in Disuq district, Kafr El-Sheikh Governorate to investigate the response of pea plants, cv. Master B, to inoculation with the Rhizobium bacteria, foliar nutrition with free living bacteria (microbin) and rhizobium + N2-fixer free living bacteria compared to uninoculated with balanced monuring by NPK rates. Four levels of inorganic NPK (1-without NPK, 2- 15 kg N + 25 kg P2O5 + native-K, 3- 40 kg N + 30 kg P2O5 + native-K and 4-60kg N + 30 kg P2O5 + native-K fed-1) were application. Soil analysis shower high content of potassium (432 and 419 ppm available K). The results indicated that inoculation of pea seeds with biofertilizer (Rhizobia + free living bacteria), improved most vegetative characters, as well as green pods yield and its components, shelling ratio, seed yield and its components, seed germination percentage, leaf contents of chlorophyll and seed content of protein. Increasing NPK rate up to 40 kg N + 30 kg P2O5 + native-K was accompanied with significant increases in vegetative growth characters, as well as green pods yield and its components, shelling ratio, seed yield and its components, seed germination percentage, leaf contents of chlorophyll and seed content of protein. Rhizobia + free living bacteria biofertilizer combined with NPK rate at 40 kg N + 30 kg P2O5 + native-K appeared to be the most efficient treatment for more vigorous growth, green pods yield and its components, shelling ratio, seed yield and its components and seed germination percentage, as well as chlorophyll content in leaves and protein content in seeds.

A laboratory study was designed to investigate the influence of seed inoculation treatments with cerialein (Azospirillum brasilense), phosphorein (Bacillus megaterium) and mixture from both on germination and seed vigor of maize (SH. 166 cultivar, yellow kernel) as compared with uninoculated seed during 2012 season. Also, field experiments were conducted to evaluate efficiency of Azospirillum brasilense (Ab), Bacillus megaterium (Bm) and mixture from both in reducing nitrogen fertilizer levels (120, 90, 60, 30 kg N/fed and without N application as a control) and their effect on emergence, growth and yield during 2012 and 2013 seasons. The results indicated that seed inoculated with combination of Azospirillum brasilense & Bacillus megaterium significantly increased seed vigor as compared with uninoculated seed. The results showed the role of Azospirillum brasilense & Bacillus megaterium in enhancing and promoting germination, activation seed vigor and development of maize. The results revealed that seed inoculated with Azospirillum brasilense & Bacillus megaterium and adding 90 kg N/fed produced good growth and yield approaching 120 kg N/fed without significant differences between both. The lowest values of growth and yield were obtained from the uninoculated treatment and without nitrogen fertilization. It could be concluded that seed inoculated with Azospirillum brasilense and Bacillus megaterium beside addition 90 kg N/fed achieved high productivity of maize.

Two field experiments were carried out at Kafr El - Wekala Sherbein Town Mansoura, Dakahlia Governorate, during the winter seasons of 2011 and 2012. The study aimed to investigate the effect of rock phosphate and Ca superphosphate with different sources of bio fertilizer (phosphorein, Microbein, mixture of each as 1: 1 and control) on broad bean plant growth, N and P uptake, yield and its pods quality. It was found that Ca superphosphate application gave rise to higher plant growth characters as well as increased N and P uptake, total yield and its pods characters and dry seeds than plants treated with the rock phosphate.
An increase in plant growth and more uptake of N and P in leaves and branches and increased total yield were found by inoculation of broad bean seeds before sowing by the mixture of microbein and phosphorein at rate of 1 : 1. Treatments of the interaction between phosphorus forms with different inoculation bio-fertilizer had no great effect on the nutritional values.
The obtained results showed that the application of microbein and phosphorein at rate of 1: 1 to maximize the yield and it may be suitable for broad bean growing under similar conditions.

Two field experiments were carried out at Kalabsho Experimental Farm, Dakahlia Governorate, Sugar Crops Research Institute, Agricultural Research Center, during 2009/2010 and 2010/2011 seasons, to evaluate the effect of nitrogen fertilizer levels (100, 120, and 140 kg N/fad), three split applications of nitrogen fertilizer (two, three and four equal doses) and harvesting dates (180, 195 and 210 days after sowing) on productivity and quality of sugar beet cv. Gazelle. Increasing nitrogen fertilizer levels from 100 to 140 kg N/fad significantly increased root fresh weight, root length and diameter, root and sugar yields/fad in both seasons. The inverse was true in total soluble solids (TSS), sucrose and purity percentages in both seasons. Splitting nitrogen fertilizer from 2 to 4 equal doses significantly increased root fresh weight, root length and diameter, TSS %, purity % and root and sugar yields/fad in both seasons. On the other hand, it decreased sucrose % in both seasons. Delaying harvesting date from 180 to 210 days after sowing significantly increased all studied characters, except for root juice purity in both seasons. Splitting 140 kg N/fad into four equal doses and harvesting at 210 days after sowing are the suitable treatment to maximize sugar beet productivity and quality under the environmental conditions of the newly reclaimed sandy soils of Kalabsho region, Dakahlia Governorate.

Two field experiments were conducted at Sakha Agricultural Research Station at Kafr El-Sheikh Governorate, Egypt, during the growing seasons of 2011 and 2012 the objective of this investigation was aimed to determine the suitable agricultural managements such as planting date, planting patterns (row width + hill spacing) and nitrogen fertilizer level) for evaluation new promising hybrid cotton [Giza 84 (Giza 70 x 51B)] Pima 62. Experiment design was conducted in split-split plots design with four replications. The main plots involved the two planting dates (early on 15 April and late on 15May planting), The sub plots involved four planting patterns (65 cm row width +25 cm hill space, 60 cm row width + 35 cm hill space, 90 cm row width + 35 cm hill space planted in two sides and 90 cm row width + 40 cm hill space planted in two sides) and the sub-sub plots included three nitrogen fertilizer levels (30, 45 and 60 kg N /fed.) Results indicated that early planting date on 15th April significantly increased seed cotton yield/fed due to the increase number of open bolls /plant and boll weight. The planting pattern (65 cm row width + 35 cm hill space) gave the good values of number of opining bolls and seed cotton yield per fed.. 45 kg N fertilizer levels significantly increased number of bolls per plant and gave good values of number of fruiting branches, boll weight, seed index and seed cotton yield. Early planting with planting pattern (65 cm row width + 35 hill space) gave the highest values for all growth and yield and yield components. The early planting and 45 kg N fertilizer interaction gave the highest values for boll weight, no. of bolls /plant and seed cotton yield/fed. The planting pattern 65 cm row width + 35 cm hill space and 45 kg N fertilizer gave the highest values for no. of bolls/ plant and seed cotton yield/fed. Early planting, planting pattern (65 cm row width + 35 cm hill space) and 45 kg N fertilizer interaction gave the highest values for boll weight, no. of bolls/plant and seed cotton yield/fed. The studied treatments did not exhibit significant effect on all fiber properties. It could be concluded that for maximizing seed cotton yield/fed produced from sown new promising hybrid cotton [Giza 84 (Giza 70 x 51B)] Pima 62 early on 15th April, at planting pattern (65 row width + 35 cm hill space) and fertilizing with 45 kg N/fed under Kafr El-Sheikh condition.

Two field experiments were conducted at New Valley Agric. Res. Station, ARC during the two successive summer seasons of 2012 and 2013 to study the effect of nitrogen fertilizer levels (Zero, 60, 90 and 120 kg N fed-1) and inoculation with cyanobacteica and / or Azospirillum sp. under the two levels of inorganic nitrogen (60 and 90 kg N fed-1) on growth, forage yield and quality traits of forage millet cv. Shandaweel-1 as well as economic evaluation of studied treatments. The experimental design was a randomized complete block with three replications.
Combined analysis of data over the two seasons revealed that growth parameters forage yield and quality traits were significantly affected by the full recommended nitrogen rate (120 kg N fed-1). The application of cyanobacteria and Azospirillum sp. combined with 75% of its recommended nitrogen rate(120 kg N fed-1) led to significantly increase in plant height by 2.5 %, number of tillers plant-1 by 11%, stem diameter by 10%, total fresh forage yield by 15% , total dry forage yield by about 8%, crude fiber yield by 7.8%, ash yield by about 20.7%, total digestible nutrient seasonal yield by7.5% and digestible crude protein seasonal yield by about 0.40%as compared with the plants received the recommended nitrogen rate (120 kg N fed-1). Application of 120 kg N fed-1 gave crude protein yield similar to that obtained from inoculation with treatment cyanobacteria and Azospirillum sp combined with 75% N fertilization (90 kg N fed-1).
The application of cyanobacteria and Azospirillum sp. combined with 75% of the recommended nitrogen rate (120 kg fed-1) is the highest in return of invested L.E. which estimated at about 3.7 L.E., meaning that every pound is spent in the cultivation of millet to this the transaction back to the farmer in the pound has been spent in agriculture plus net return, which is estimated at 2.7 pounds and considered the best studied treatment.
From the above mentioned results it could be recommended that the application of cyanobacteria and Azospirillum sp. Combined with 75% of the recommended mineral nitrogen gave the highest productivity of forage millet and a higher net return for the farmer under NewValley conditions.
