Effect of dairy factory effluent on dry matter production, yield and uptake of nutrients in greengram and pearl millet crops

A pot culture experiment was conducted during rabi 2009 at S. V. Agricultural College, Tirupati, Andhra Pradesh to study the effect of dairy factory effluent on dry matter production, yield and nutrient uptake by greengram and pearl millet crops. The dry matter production, yield and N, P, K and S uptake by greengram and pearl millet crops increased with increase in the levels of dairy factory effluent application from DFE0 to DFE3.0. The uptake of K and S was higher in pearl millet crop, whereas the uptake of N and P was higher in greengram crop. The interaction effect between crops and levels of dairy factory effluent on yield, dry matter production and uptake of N, P, K and S was found to be significant at all stages of crop growth.
