ASSESSING THE YIELD AND JUICE QUALITY OF SUGARCANE UNDER AGRO-CYCLING OF PAPER MILL SOLID WASTES AND TREATED EFFLUENT IRRIGATION

M. Suguna Devakumari

Abstract

The paper mills are generating appreciable quantities of solid wastes and effluent. The scientific ways and means of recycling in an integrated, eco-friendly manner these solid wastes and effluent for agricultural purposes had been the main objective of this present investigation. The field experiment with sugarcane as test crop utilizing both well water and effluent as sources of irrigation and solid wastes as amendments revealed that effluent irrigation increased the cane yield by 5.78% over well water irrigation. The number of millable canes was 5.53% higher under effluent irrigation than well water irrigation. The effluent irrigation coupled with Fly ash 20 t ha-1 + Bio sludge 6 t ha-1 + 75% NPK increased the yield of canes by 30.9% compared to 100% NPK under well water irrigation. The sugarcane juice analysis revealed that effluent irrigation improved the quality.
