| This study was carried out at the Village of Algraydh, Kafrelshiekh Governorate, Egypt, during the summer seasons 2016 and 2017 to conclude whether, and if so how, soybean growth, yield and seed oil percentage are affected by phosphorus and sulfur mineral fertilizers levels. The experiment was laid-out in strip-plot design with four replications. The vertical-plots included five levels of phosphorous (P) fertilizer (0 without as control, 10, 20, 30 and 40 kg P2O5 fed-1). While, the horizontal-plots assigned with five levels of sulfur (S) fertilizer (0 without as a control, 20, 40, 60 and 80 kg S fed-1). Application of 40 kg P2O5 fed-1 produced the maximum averages of growth characters, yield and yield components as well as seed oil percentage. Furthermore, using 30 kg P2O5 fed-1 came after the previously mentioned level and without significant differences between them in both seasons. Adding 80 kg S fed-1 produced the highest averages of all studied traits, followed by 60 kg S fed-1 and without significant differences between them in both seasons. It could be concluded that combined application of 30 kg P2O5 fed-1 plus 60 kg S fed-1 is recommend for improving the productivity and seed oil percentage of soybean under the ecological conditions of Kafrelsheikh Governorate, Egypt. | ||
