Abstract

To determine the effect of row spacing, nitrogen and potassium fertilizer on silage yield and its dependents components on corn (Zea mays L.cv.Sc704), an experiment was done as split-split plot in randomized complete block design based with four replications. Row spacing was chosen as main plots including: 65cm, 75cm and 85cm, three levels of N (250, 350 and 450 kg ha-1) in sub plots and three levels potassium (100, 150 and 200Kg/ha) in sub-sub plots were laid out. The results indicated that row spacing, were affected on plant dry weight, dry ear weight, dry leaf and dry stem weight. While the silage yield, ear yield, leaf yield, plant dry weight and dry ear weight, were affected by nitrogen and showed significant difference. Potassium had significant difference on plant dry weight, dry leaf and dry stem weight. The most silage yield (42/23t/ha) and dry plant weight (13.88 t/ha)obtained from 65cm row spacing that dry plant weight had significant difference with other row spacing. Amount of 450kg/ha nitrogen was caused the most silage yield (41/6t/ha) and plant dry weight (13.36 t/ha) that had not significant difference with usage of 350kg/ha nitrogen. The most silage yield (40/75t/ha) obtained from 200kg/ha potassium that had not significant difference with other potassium usage levels. The most plant dry weight (13.36) obtained from 150kg/ha potassium that had not significant difference with 200 kg/ha potassium usage levels
