Abstract
Two field experiments were carried out on calcareous soil in Northern Tahreer region during 2000 and 2001 summer seasons to study the effect of nitrogenous fertilizers (unfertilized, 60 kg Niled. and 15 kg N/ fed. + rhizobium inoculation), phosphatic fertilization (untreat-ed, soil application of 30 kg P2 02 / fed. and foliar spraying of 200 liter / fed. super-phosphate supematant (prepared by soaking 4 kg Ca- su-per-phosphate in 200 liter lap water and kept overnight, then decanted and filtered through a piece of cloth), twice after 30 and 50 days from sowing) and their possible combinations on some economical characters i.e., seed, straw, protein and oil yield / fed. of soybean Crawford cultivar. Statistical analyses cleared significant effects on all studied characters duo to both nitrogenous and phosphatic fertilization. The highest values were obtained by applying 15 kg N/fed. + rhizobium inoculation for the nitrogenous fertilizers and foliar spraying of 200 liter / fed. super-phosphate supernatant twice after 30 and 50 days from sowing for the phosphatic fertilization. Amongst the interaction between nitrogenous and phosphatic fertilization, data showed significant effects on seed. protein and oil yield I fed. The superior treatment was 15 kg N / fed. + rhizobium Inoc-ulation + foliar spraying of 200 liter / fed. super-phosphate supernatant, twice after 30 and 50 days from sowing for increasing all studied crite-ria.
