Abstract
Four different amounts of nitrogen(40kg,20kg,10kg and 0kg/667m~(2)) for two sugarcane varieties,nitrogen fixation RB_(72-454) and F_(134) were conducted on flat field and slope land to investigate the fertilizer effects on yield.The results from the stubble cane planting and new planting for one year showed that the three different amounts of nitrogen applied can increase the seedling rate,tillering ability,height of stem,stem diameter,single stem weight,effective stems and yield compared with those without nitrogen applied in RB_(72-454)variety planted on the flat field and slope land,but there was no significant relation between yield and different amount of nitrogen applied.The yield,sugar content and sugar production of RB_(72-454)with 20kg/667m~(2) of nitrogen planted on the flat field were 8686kg/667m~2,15.72% and 1159kg/667m~2,which increased by 50.1%,1.49% and 65.6% compared with those of F_(134) respectively.The yield, sugar content and sugar production of RB_(72-454)with 20kg/667m~(2) of nitrogen planted on the slope land were 6982kg/m~(2),15.53% and 927kg/m~(2),which increased by 71.7%,1.06% and 85.4% compared with those of F_(134) respectively.
