Effect of Coated Urea Mixed with Urea on Sugarcane Yield

The oil of Idesia polycarpa var.vestita of the nature resources extracted from the fruit of tree used as controlled material for producing the Coated urea fertilizer was studied.The soil incubation experiment was carried out and the fertilizer treatment was seven.The coupling Coated urea and urea was studied.The method was adopted to measure the coated urea nutrient.the result showed the preliminary solubility rate of nitrogen coated urea was 12.2% and in comparison with applying urea,the preliminary solubility rate of nitrogen decreased 67.9%.The effect of Coated urea was to increase SPAD in the sugarcane.The Stalk weight in treatment 5 was more 0.31g than that of CK and was more 0.21 g than that of Coated urea of one way and was 0.25 g more than that of urea of one way.Plant height in treatment 5 was 50.5 cm more than that of CK and was 27.8 cm more than that of urea of one way.The treatment 5(Coated urea 70%+ urea 30%) was the best treatment.
