Effect of concentrated organic manure, nitrogen and sulphur on the productivity and economics of sugarcane (Saccharum officinarum)

Abstract

An experiment was conducted during the spring season of 1995 96 and 1996 97 on sandy loam soil of Pusa, to study the effects of different levels of concentrated organic manure, nitrogen and sulphur on growth, yield and economics of sugarcane ( Saccharum officinarum L. ). Concentrated organic manure and N fertilization significantly influenced growth parameters and yield attributes, and crop responded up to 20 q organic manure, 150 kg Nlha, respectively, for cane yield and net profit. Integration of concentrated organic manure N further induced significant increase in cane yield and net profit over thelr individual application. Concentrated organic manure 20 q with 150 kg Nlha resulted in significantly higher cane yield and net profit over 200 kg Nlha alone. Sulphur fertilization did not cause significant variation in cane yield, though there was improvement in sucrose (%) in juice, but it was reduced by increase in N levels.
