Abstract
The effect of N fertilization on agronomic traits and yield of sugarcane in middle area of Guangxi,was investigated to rationalize the N fertilizer in sugarcane production.Field experiments were conducted to investigate the effects of different dosages of N fertilizer on growth characteristics and yield of sugarcane in Xingbin District of Guangxi during 2010—2011.Results show that In sugarcane tillering,early elongation,process maturity,when N 345 kg/hm2,with the increase in the amount of nitrogen fertilizer,the growth potential of sugar cane growing.And non-nitrogen treatment(N0) compared to N treatment of the effective number of stems,one stem weight,respectively,yield an average of 2.93%,6.30% and 10.28%.When a certain level of nitrogen fertilizer(N 750 kg/hm2),the effective number of stems of sugarcane continued to increase with the amount of fertilizer decreases,reducing nitrogen agronomic efficiency is also more obvious.Seen in Guangxi sugarcane N 119.85 kg/hm2,both to ensure that sugar cane yield,but also ensures efficient use of resources fertilizer,nitrogen is a more reasonable level.
