Agronomic trials on sugarcane crop under Faisalabad conditions,Pakistan

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,i 4 &p 4 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 v 2 p 4 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 i 4v 2 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.
