In order to investigate the influence of spraying with proline and potassium humate (PH) on productivity and chemical components of Broad bean, cv. Koprosay, two field experiment were conducted at a private Farm in Rowad Village belong to Sahl El-Husseiniya, Sharkia Governorate throughout 2016 and 2017 seasons. Randomized complete blocks design was used with three replications. Height of plant, No. of leaves/plant, total chlorophylls, leaves fresh and dry weight, length and wide of pod, green seeds number per pod, the weight of 100 green seeds, total yield, N, P, K and proline percentages in leaves N, P, K, total carbohydrates and crude protein percentages in green pods were estimated. Spraying broad bean plants with 2 L PH/fad in addition 100 mg proline/L produced the highest values of all estimated traits in both seasons. Accordingly, it could be suggested that spraying broad bean plants grown under saline soil with 2 L PH/fad and 100 mg proline/L to improve growth characters and yield in addition to chemical components of broad bean.

This study was carried out during 2015 and 2016 seasons at a private Farm in Road Village in Sahl El-Husseiniya, Sharkia Governorate to study the influence of foliar spraying with three potassium sources at three concentrations from each of them i.e. potassium sulfate1,2 and 4 g/ L; potassium silicate at 1,2,and 4cm/L as well as potassium humate at 1,2 and 4 cm / L beside without foliar spraying (control) to reduce the bad effects salinity stress on growth, yield and quality of pea Master B cultivar under saline soil conditions. The experiment was carried out by using completely randomized blocks design with three replications. Spraying pea plants with potassium silicate (4 cm/L) significantly increased and created the maximum means of all studied traits (growth, yield and yield attributes and chemical constituents in the leaves and seeds) as compared to other studied treatment in the two seasons. Spraying with potassium silicate (2 cm/L) was the second best treatment, followed by potassium silicate at the rate of 1 cm/L, then potassium humate at the rate of 4 cm/L and 2 cm/L in the two seasons. Conversely, the lowest means of these traits resulted from control treatment in the two seasons. Overall, using potassium silicate at different rates as foliar application exceeded using potassium humate at different rates exceeded potassium sulfate at different rates in the two seasons. Concerning proline % in leaves, it had adverse trend comparing with other studied traits in the two seasons. Generally, it could be recommended that spraying pea plants through 4 cm potassium silicate/L to enhance growth, yield and yield components and chemical constituents of pea under the environmental conditions of same research.

A field experiment was carried out at a private Farm in Rowad Village belong to Sahl El-Husseiniya, Sharkia Governorate during the two growing seasons of 2016 and 2017 to study the effect of spraying potassium silicate and adding ammonium thiosulfate (ATS)as soil drenching at three levels on vegetative growth, yield and its components and chemical constituents of eggplant grown under salinity soil( Black Beauty cultivar). The experiment was carried out by using split-plots system in a randomized complete blocks design with three replications. The main plots were arranged with potassium silicate treatments. While, the sub-plots assigned to ammonium thiosulfate levels. The obtained results of this investigation can be summarized as follows: Foliar spraying eggplant plants with potassium silicate levels significantly improved vegetative growth, the yield and its components along with chemical constituents either in the leaves or in the fruits compared with control treatment during both seasons. The highest values of these traits were resulted from using concentration of 6 cm potassium silicate/L in both seasons. Concerning to the effect of ammonium thiosulfate ,it can said that vegetative growth, yield and its components and chemical constituents of either the leaves or in the fruits of eggplant were significantly influenced by different ammonium thiosulfate (ATS) levels adding as drenching around the plants in the both seasons. The maximum values of these characters were produced from using 15 L/fed or 10 L/fed of ATS, respectively in both seasons.While the favourable results on the growth,yield and its components as well as the chemical constituents in the leaves or the fruits were obtained from the interaction between the treatment of foliar spray with 6 cm potassium silicate and adding 15 L/fed from ammonium thiosulfate as soil drenching to obtain the highest results. For that, it could be recommended that foliar spraying eggplant plants grown under salinity soil with 6 cm potassium silicate/L 3 times with using 15 L ATS/fed as soil drenching to enhance vegetative growth characters, yield and its components and chemical constituents of eggplant fruits under the environmental condition of this research.

Two experiments were carried out at a private Farm in Rowad Village belong to Sahl El-Husseiniya, Sharkia Governorate through 2019 and 2020 seasons to determine the impact of organic,chemical fertilizations and spraying with some plant stimulants (yeast extract, potassium silicate and chicken manure tea) on growth traits, yield and its components and chemical ingredients of eggplant(Black Beauty cultivar) grownup under saline soil. The experiments were conducted using split-plots design with three replications. Organic and chemical fertilization treatments were arranged in the main-plots. The sub-plots were assigned to some plant stimulants (yeast extract, potassium silicate and chicken manure tea) treatments.The obtained results showed that growth, yield and its components and chemical ingredients of both eggplant leaves and fruits were significantly affected by the different levels of organic and chemical fertilization in both time of years. The supreme values of these traits were obtained from using 100%of (NP and K)chemical + 0% of (FYM) farmyard manure fertilizers,50%of NP and K+ 50% of FYM and75%of NP and K+ 25% of FYM fertilizers.Spraying eggplant plants with potassium silicate, chicken manure tea and yeast extract significantly improved growth, yield and its components and chemical in gredients in leaves and fruits through both years. It could be recommended that spraying eggplant plants with yeast extract with using50%of NP and K+ 50% of FYM to enhance growth, yield and its components and chemical ingredients under the ecological situation of this research.

Two field experiments were carried out at a Farm in El-Mataryia district, Dakahlia Governorate during the two growing seasons of 2011 and 2012 to study the effect of organic fertilization and ammonium thiosulfate (ATS) levels that reduce salinity effect on vegetative growth, yield and its components and chemical constituents of eggplant crop Black Beauty cultivar. The experiments were carried out by using splitplots system in a randomized complete blocks design with three replications. The main plots were arranged with organic fertilization treatments. The sub plots were assigned to ammonium thiosulfate levels. The obvious results of this investigation can be summarized as follows: Using farmyard manure (FYM) and potassium humate (KH) treatments significantly increased all studied characters as compared with other organic fertilization treatments in both seasons. Application rice residues (RS) caused significant increases on all studied characters as compared with control treatment (without organic fertilization) in both seasons. All studied characters were significantly influenced by different ATS levels in the both seasons. The highest values of these traits were resulted from using 30 L/fed and 40 L/fed of ATS, respectively in both seasons. Generally, it could be recommended that using FYM or KH, respectively along with 30 L ATS/fed to enhance vegetative growth characters, yield and its components and chemical constituents of eggplant fruits. Also, it could be recommended that using RS combined with 30 L ATS/fed to enhance studied characters as compared with control treatment (without organic fertilization) and also to reduce sources of environmental pollution and maintain human health.
