Abstract :

In order to evaluation of N-Fertilizer sources and amounts effect on yield and its components in single cross 704 corn, an experiment was conducted in research field of Islamic Azad University-Miyaneh branch. In this study, two levels of  N-Fertilizer including Amonium Nitrate and Urea with amounts including 100, 160 and 220 Kg of pure Nitrogen per hactar as a factorial design in compeletly randomized blockes with four replications was run. One of plots in each treatment was considered as control without N-Fertilizer receiving. Plants was planted as farrow system on the rows with 75 cm intervals and 67.000 plants/ha density in 23th of Ordibehesht. N-Fertilizers were applied in three times including simultaneously with planting, four and eight leave stages as top dressing. The plants were selected from 5 m2 of three middle rows for determining of seed yield and biological yield in physiological ripping stage and 15 plants randomizly were selected from each plots for yield component and head numbers in a plant in row and seed number in row were counted and 1000 seeds weight was evaluated. It is revealed that Amonium Nitrate application has higher yield than Urea application and 160 and 220 Kg/ha of pure Nitrogen has the same or more then yield of control and 100 Kg/ha treatment. The reason of high yield in Amonium Nitrate treatment has contributed with corn efficiency in Nitrogen Uptake. Low yield in Urea treatment is related to Nitrogen wasting by sublimitation and washing.
