摘要：With increasing dairy industrial development, safe disposal of industrial effluent has become anecological challenge. Finding suitable eco-friendly techniques for the potential utilization of thesereleased effluents as a source of nutrients become essential. The present investigation was carriedout to screen the effect of dairy effluent water in combination with FYM @ 5 t ha -1 , gypsum @1 t ha -1 andsewage-sludge @ 3 t ha -1 on the yield, nutrient content and uptake by castor-sorghum sequence aswell as physico-chemical properties of soil. The findings revealed a remarkable effect on yield andnutrient uptake by crop with primary treated dairy effluent water when combined with FYM andgypsum. The application of FYM @ 5 t ha -1 or gypsum @ 1 t ha -1 in the soil, increased the yield, nutrientcontent and uptake by castor as well as succeeding fodder sorghum crop, when applied with tubewell, as well as treated effluent water. Further work was carried out to study the effectiveness andsuitability of dairy effluent on soil properties after harvest of the crop. Application of treated effluentwater alone increased EC and reduced the availability of nutrients (N, P, K, S), while combination withFYM enhanced the soil fertility.
