A field experiment was conducted during the crop season of 1998-99 and 1999-2000, to study the influence of integrated use of organic sources with different levels of mineral nutrients. Integrated use of pressmud at 5 tonnestha with NPK application @ 100% of the recommended dose influenced the yield attributes, nutrient up- take and remarkably increased the cane yield. It was comparable with conjuctive use of pressmud @5 tonnestha with NPK @ 100% of the recommended dose. But the magnitude of variation in cane yield was only marginal. Hence, it was possible to save 25% of the recommended dose of NPK when pressmud was applied 8 5 tonnest ha. There was a drastic decrease in cane growth and cane yield when resorted to mineral nutrition alone. The juice quality also improved when organic sources were integrated with mineral nutrients.References
