Abstract:
To evaluate the effect of integrated organic nutrient sources on yield of barnyard millet, the field experiment was conducted in the farmer’s field at Anaikkudam Village, Udaiyarpalayam Taluk, Ariyalur District of Tamil Nadu with eight treatments, thee replications under randomized block design (RBD). The eight treatments were T₁– Control, T₂ –100% RDF, T₃ – CPC + BMP + PG, T₄ – CPC + PG , T₅ – CPC+ BMP , T₆ –T₃ + LBF , T₇ – T₄ + LBF and T₈ – T₅ + LBF. The recommended dose of fertilizers 40: 30: 50 kg N, P₂O₅ and K₂O ha^-1 were adopted and incorporated. As per the treatment schedule, different organic nutrient sources viz., coir pith compost (CPC), borne meal powder (BMP), panchagavya (PG) were given. Liquid bio-fertilizers (LBF) were also supplied as foliar spray @ 1% on 30 and 60 DAS. The key component of modern waste reduction is reduce-reuse-recycle. The use of animal waste in farming operations can reduce the quantity and hauling costs of commercial fertilizer. The results revealed that application of 100% RDF (T₂) recorded significantly the highest grain yield of 2172 kg ha^-1. The next best was found to be with CPC+BMP+PG+LBF (T₆) registered the grain yield of 1923 kg ha^-1. The combined application of coir pith compost @ 10 t ha^-1, bone meal powder @ 1 t ha^-1 and panchagavya @3% along with liquid bio-fertilizers @ 1% recorded the favorable effect on soil properties compared to control and chemical fertilizers applied plot.
