بررسی آرایش کاشت، تراکم و روش مصرف کود بر عملکرد و دیگر صفات زراعی ذرت دانه ای رقم سینگل کراس 704 در شرایط کوهدشت

In order to stady of planting pattern, plant density and fertilizer method on corn (cultivar: sc704) an experiment was assessed on Kuhdasht, Lorestan during the year 2005. The design was a strip plot- factorial in a randomized compelet block design with four replications. Fertilize method )current method:scatter on field and strip method:10 cm depth and middle of back farrow) as horizontal plots, planting pattern(one row and two rows planting on back farrow) and plant density (70000, 85000 and 100000 plant /ha) were applied factorial in vertical plots.The results showed that effect of fertilizer method was significant for number of grain per ear , ear height and grain yield. Effect of planting pattern was significant for grain yield and Plant density was significant for traits plant height and grain yield. Intractrons of fertilizer method × planting patron, fertilizer method × planting patern were significant for grain yield whereas intraction of fertilizer method × plant density × planting pattern was no significant.
