| Abstract | ||||
| Two field experiments were conducted at the Experiment and Research Center, Faculty of Agriculture at Moshtohor, Zagazig University during 1996 and 1997 seasons. Experiments were designed to study the response of growth and seed yield of soybean to levels of N + P fertilizer ( N 0 + P 0. 30 kg N + 15 kg oy‘fed and 60 kg N + 30 kg PzOy’fed) and manganese levels (0. 2.5 . 5.0. 7.5 and 10.0 kglfed) as soil application in combination of 15 treatments. increasing NP fertilization rates up to 60 kg N + 30 kg Pgoslfed significantly increased plant height. number of branches. number of pods and seeds per plant, seed yield per plant. 100vseed weight. seed yield (kgr‘fed) and protein percentage of soybean.However.this treatment decreased oil percentage of seeds. Plant height number of brancheslplant number of pods and seeds per plant, seed yield per plant, too-seed weight, seed yield (kgr’ted). As will as protein and oil percentages increased significantly by increasing manganese level up < /p> to 5.0 kgr'fed. Higher seed yield per plant, too-seed weight as well as seed yield (kglfed). protein and oil percentages significantly increased by application of N + P Fertilizer at 60 kg N + 30 kg oslfed with 5.0 kglfed of manganese as soil application in the two growing seasons, respectivelylt couid be concluded that under the circumstance of these experiments, would recommended to fertilize soybean with 60 kg N + 30 kg P205/fed with soil application of 5.0 kg/fed Mn (Mn-EDTA-15 % Mn). | ||||
