Abstract
This research was conducted to study the effect of different nitrogenous fertilizers ( urea, urea formaldehyde and sulfur coated urea) whether applied solely or combined with the nitrogen fixing bacteria Azospirillum sp.in presence or absence of the growth osmo-regulator proline on maize plants grown on a saline-sodic soil located at Sahl El-Tina,NorthSaini.Calcium superphosphate was added during the soil preparation at a rate of 309.4 kg P/ha-1 whereas potassium was added in the form of K2 SO4 ata rate of 166.6 kg K ha-1intwo equal doses after 21 and 45 days of planting. The experimental design was a randomized complete block factorial in three factors i.e. the nitrogenous fertilization, biofertilization and spraying with proline.The results showed that maize grain yield increased significantly due to application of N and sulfer coated urea whereas the control treatment was of the least effect on maize grain yield. Biofertilization and spraying plants with proline maximized effect of the nitrogenous fertilizers on grain yield. The applied nitrogen fertilizers especially the sulfur coated urea significantly increased weight of 100 grains. Spraying with proline and biofertilization were of significant effects on weight of 100 grains. All the applied nitrogenous fertilizers with special concern of the sulfur coated urea increased plant uptake of NPK and the effect became more obvious with the biofertilization and proline application.
