Abstract
The present experiment has been conducted to study the effects of different planting densities(9×104,12×104,15×104,18×104 buds/ha) on agronomic characters and sugar content of four sugarcane varieties,viz.,Guitang 21(GT 21),Guitang 26(GT 26),Guitang 27(GT 27) and Guitang 28(GT 28).The results showed that the number of effective stalks in varieties GT 26 and GT 27 increased with increasing the planting densities,while they were highest at the planting density of 15×104 buds/ha in varieties GT 21 and GT 28.The variety GT 21 recorded highest cane yield and sugar content at 15×104 buds/ha density,while in varieties GT 26,GT 27 and GT 28,it was highest at 12×104 buds/ha density.Under the moderate fertility conditions,all of these varieties were found suitable for planting with the density of 9-12×104 buds/ha.The cane yield of GT 28 decreased significantly with high planting density,however,the sucrose content did not differed significantly at different planting densities.
