Effect of methods and amounts of complete fertilizer using on yield and yield components of corn variety in Shahr-e-Rey region

Due to study the effect of methods and amounts of complete fertilizer on yield and yield components of corn variety, an experiment was done during 2016 as split plot based on completely randomized blocks design with 3 replications at Ghaleh-no of Shshr-e-Rey region. The experimental factors contains: complete fertilizer as main factor in 7 levels: No application, recommended application in irrigation (10 kg/ha), 50% less than recommended application in irrigation (5 kg/ha), 50% more than recommended application in irrigation (15 kg/ha), recommended foliar application (2 kg/ha), 50% less than recommended foliar application (1 kg/ha), 50% more than recommended foliar application (3 kg/ha) and variety as sub factor in 3 levels: S.C. 704, S.C. 703 and S.C. 700. The results showed that the highest and lowest plant height, 1000 seed weight, rows number in ear and seed number in ear, forage yield and growth indices as CGR, RGR, NAR gained at 50% more than recommended application in irrigation and no application alternatively. According to findings, 50% more than recommended foliar application improved fresh forage yield 8.3% than control. Based on the results, S.C. 704 had superiority than the other varieties in agronomical and physiological characters.
