Abstract

Groundnut productivity can judiciously be improved by integration of organic manures with inorganic fertilizers under suitable combination. Therefore, a study was conducted during 2019 at Faculty of Agriculture, Annamalai University, Tamil Nadu, India to evaluate the effects of different organics and biofertilizers on growth and yield of groundnut. The experiment was laid out in a Randomized Block Design with three replications with treatments comprised of recommended dose of fertilizers (RDF) @ 25: 50: 75 kg/ha + farm yard manure (FYM) @ 10 t/ha, RDF + Vermicompost @ 5 t/ha, RDF + Poultry manure @ 2.5 t/ha, RDF + Compost coir pith @ 5 t/ha, RDF + Rhizobium (seed treatment) @ 25 g/kg of seed, RDF + PSB (seed treatment) @ 30 g/kg of seeds and control (RDF). Fertilizing the crop with RDF + farm yard manure (FYM) @ 10 t/ha increased the pod yield to a tune of 2086 kg/ha with kernel yield of (1403 kg/ha) and haulm yield (4002 kg/ha) significantly superior over other combinations in groundnut. Therefore, application of locally available FYM collected within the farm has a possibility of increasing an additional income to the farming community.
