| Abstract: | Effects of nitrogen application on the growth,yield and quality of peanut were studied in field experiments.The results showed that the yield of pods increased along with nitrogen amount increases when application amount was less than 120 kg/hm2.The highest yield was 3639.88 kg/hm2 and increased by 18.61% as compared with control when the amount of applied nitrogen was 120 kg/hm2.Under 0~150 kg/hm2 nitrogen fertilizer rate,applying nitrogen fertilizer could promote their absorption of N,P and K,regulate the... |
