In the present studies field experiments were conducted to study the production potential of September planted Sugarcane (Saccharum officinarum L.) under varying agro-management practices for the year 2007-2008. Two sugarcane clones viz., S2002-US-637 and CP 85-1491 show good growth potential were evaluated at five bio-fertilizer and chemical fertilizer levels in different combinations. Fifty percent bio-fertilizer+ 50% recommended dose of chemical fertilizer increased the cane yield along with reduced environmental pollution. In field experiments, I4 & P4 treatment significantly affected agronomic characteristics such as cane height (cm), cane diameter (cm), cane yield (000 t ha-1), whereas number of tillers ha-1, number of mill-able canes ha-1 and sugar recovery% were non significantly affected over control. The sugarcane promising clone S2002-US-637 showed better performance over CP 85-1491. The interaction V2 P4 significantly affected all parameters except sugar recovery%. Furadon 20 kg ha-1 at sowing+ Furadon 40 kg ha-1 in April/May+ Furadon 40 Kg ha-1 in June/July controlled the pests of sugarcane and increased the yield of promising sugarcane clones. The interaction I4V2 significantly affected all parameters except sugar recovery%. Trench planting saves 50% irrigation water but alternate skip irrigation further improves cane yield in addition to saving of same amount of water.
