Two field experiments were carried out during the winter seasons of 2008/09 and 2009/10 at farm in Disuq district, Kafr El-Sheikh Governorate to investigate the response of pea plants, cv. Master B, to inoculation with biofertilizer (Halex-2) and different concentrations with boron (0, 5, 10 and 15 ppm) as a foliar application. The results indicated that inoculation of pea seeds with biofertilizer (Halex-2), 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 boron concentration up to 10ppm 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.The highest boron concentration at 10ppm combined with Halex-2 biofertilizer 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 contents in leaves and protein content in seeds.

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.

This investigation carried out in cooperation work between Horticulture Department, Faculty of Agriculture, Kafr El-Sheikh and Horticulture Research Institute during the period of 2001 to 2010 through two stages. The first stage: Six strains of okra were obtained after six generations of inbreeding and selection from the local cultivars. The six selected strains and the original cultivars were evaluated during the summer season of 2006 for yield and horticultural characteristics. Evaluation results indicated that the, Strain No. 1 had the lowest values of vegetative traits and it produced the largest values of early and total yield as a number and weight of pods, therefore, this strain was chosen as a new cultivar under name of Sakha-1 after produced their seeds in isolated area in two successive years. The second stage: The new cultivar and two commercial cultivars, i.e., Balady Green and Sabahia-1 cultivars were evaluated in summer seasons of 2009 and 2010 in the Experimental Farm of Sakha Agricultural Research Station. The new cultivar Skha-1 surpassed the Balady Green and Sabahia-1 cultivars for early and total yield as a number and weight of pods and pod quality.

This study was carried out during the two summer seasons of 2011 and 2012 at Sakha Agricultural Research Station Farm, Kafr El-Sheikh Governorate, Egypt on summer squash (Cucurbita pepo L.) El-Askandarani cultivar to study the impact of plant spacing(30,40 and 60cm between plants), nitrogen fertilizer sources (organic and inorganic) and foliar spray with biostmulants(garlic or yeast extracts) and their interactions on vegetative parameters and leaf chemical constituents.Resultes indicated that, the highest values of vegetative growth characters i.e., plant length, number of leaves, fresh and dry weight, leaf area and chlorophyll contents in leaves as well as chemical constituents of leaves(N, P, K, Fe, Zn and Mn)were recorded when plants growing at 60 cm between plants. Squash plants sprayed with 2.5cm\l garlic extracts recorded better growth performance and higher values of chemical constituents of leaves than unsprayed plants. Also fertilized plants with 50%organic+50%inorganic recorded the highest significant values of most aforementioned parameters compared with control. The best results of both vegetative growth parameters and chemical constituents of leaves were recorded when plants growing at 60cm between them and fertilized by 50%organic as compost +50%inorganic as ammonium nitrate (100 kg/fed.) and sprayed with garlic or yeast extracts at 2.5cm/l in both seasons. Therefore, this treatment could be recommended for improving squash plants performance under similar condition of this study.
