EVALUATING THE YIELD AND PROTEIN CONTENT OF FODDER GRASS UNDER PAPER MILL EFFLUENT IRRIGATION AND SOLID WASTES AMENDMENT

M. SUGUNA DEVAKUMARI

Abstract

Using alternative water resources such as treated industrial effluent is considered very important to produce crops and green forage due to irrigation water shortage, especially in arid and semiarid regions. The objectives were to investigate the effects of irrigation with treated effluent of paper mill and amendment of paper mill solid wastes on Cumbu Napier fodder yield and quality. Results indicate increase in grass biomass yield under I2T4 (Effluent irrigation coupled with Fly ash 10 t ha- 1+ Bio sludge 6 t ha-1 + 75% NPK over I1T1 (100% NPK) was 44.7 percent during II cutting and 52.6 percent in III cutting and the protein content also improved considerably. Treated effluent use in irrigation of Cumbu Napier fodder and application of solid wastes are considered as useful alternative disposal method of wastewater without the risk of accumulation of toxic elements in the soil and the maintenance of the environment.
