Two field experiments were carried out at the Experimental Research Station, Faculty of Agriculture, Moshtohor, Benha University, Kalubia Governorate, Egypt, during 2016/17 and 2017/18 winter seasons this is to evaluate the efficiency of 4 treatments: phosphate fertilization sources soil addition (super phosphate (SP), rock phosphate (RP) + phosphate dissolving bacteria (PDB) , sulphur (S) + phosphate dissolving bacteria (PDB) and RP + S+ PDB) and three spraying levels of lithovit ( 0 (tap water), 0.5 and 1.0 g/L ), to enhance the availability of phosphorus from rock phosphate and their effects on vegetative growth parameters, chemical composition, yield and yield components of faba bean seeds cv. Sakha 4. Experiments were designed and layed out as split plot design where lithovit spraying foliar application levels randomly distributed in the main plots and phosphorus fertilization sources in the split plots of three replicates. Results could be concluded as follows:
Application of different phosphate fertilization sources induced significant increases growth characteristics, yield, its components and chemical constituents of faba bean (Sakha 4). Fertilizer application of RP + S+ PDB produced 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 first 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. |
