Abstract
A field experiment was conducted on integrated nutrient management in late planted sugarcane (Saccharum officinarum L.) wheat (Triticum aestivum L. emend. Fiori Paol.) system during 1995 96 to 1998 99 at Modipuram, Meerut, Uttar Pradesh. Significantly higher cane yield (56.1 1 tonnestha) was recorded with 100% NPK (N20,P65K,5) applied on soil test basis. Substitution of 25% N through pressmud and farmyard (FYM) manure re sulted yield at par with 100% NPK applied through chemical fertilizers, while substitution of 25% nitrogen through pressmud, FYM or green manuring of cowpea in plant crop of sugarcane increased the cane yield of ratoon signifi cantly (97.90 tonnestha). Wheat yield was significantly higher with 100% NPK (N,20P60K,o) applied on soil test ba sis. Any curtailment of chemical fertilizer reduced the wheat yield remarkably and significantly lower wheat yield (2.70 tonnestha) was recorded when 25% N need of wheat was substituted by sugarcane stubbles. Quality param eters such as brix, sucrose and purity showed that application of chemical fertilizer alone reduced the value of these parameters, while combination of both chemical and organic manures improved them. Soil analysis revealed that pH of the soil decreased from initial value (8.20) with the application of fertilizers and the magnitude of de crease was more when organic sources were applied along with chemical fertilizers. Soil organic carbon (%) did not show any remarkable change, while available P205 and K20 increased with the combination of chemical fertil izer and organic source, such as pressmud, followed by FYM.
