Two field experiments were conducted at the Experimental Research Station, Faculty of Agriculture, Moshtohor, Benha University, Qalyoubia Governorate, Egypt, during 2016/17 and 2017/18 winter seasons this study is to evaluate the effectiveness of four treatments: phosphate fertilization sources as soil addition (super phosphate (SP), rock phosphate (RP) + phosphate dissolving bacteria (PDB), sulphur (S) + phosphate dissolving bacteria (PDB) and RP + S+ PDB) with three spraying levels of lithovit ( 0 , as tap water, 0.5 and 1.0)g/L ), to increase the availability of phosphorus from rock phosphate and their effects on vegetative growth parameters, chemical composition, yield and yield attributes of faba bean plants cv. Sakha 4. Experiments were designed and carried out as split plot design where lithovit as foliar application levels randomly distributed in the main plots and phosphorus fertilization sources were in the split plots of three replicates. Results determined as follows: Application of different phosphate fertilization sources induced significant increases growth characteristics, yield, its components, and chemical constituents of faba bean (Sakha 4). In addition, Fertilizer application of RP + S + PDB formed the tallest plant heights, No. of branches / plant, chlorophyll content, yield and its components and seed index as well in the two respective seasons with variable significant magnitudes. Also, Nitrogen (%), Phosphorus (%) and Potassium (%) were increased in the 1st season where fertilized with RP + S + PDB. Foliar application of lithovit, 1.0 g/L level exerted the highest values of growth characteristics, yield, its components, and chemical constituents of faba bean (Sakha 4) as well in each of the two growing seasons with different significant magnitudes. |
