Abstract:
An experiment was conducted during the kharif season 2021, at the Crop Research Farm, Department of Agronomy, Naini Agricultural Institute, Sam Higgin bottom University of Agriculture, Technology and Sciences (SHUATS), Prayagraj (U.P.) to study the effect of biofertilizers and spacing on growth and yield of groundnut (Arachis hypogaea L.). Seed inoculation with biofertilizers VAM (Vesicular Arbuscular Mycorrhiza) - 1.5g/kg seed, PSB (Phosphate Solubilising Bacteria) – 5g/kg seed, Rhizobium – 20g/kg seed and Trichoderma – 5g/kg seed. Seeds were sown at a depth of 5cm with (25cm × 20cm and 30cm × 15cm) - two different spacings maintaining row to row and plant to plant distance. The Trichoderma + 30cm x 15cm significantly increased the growth attributes viz., plant height (46.47cm), no. of nodules/ plant (92.84), dry weight (27.56g/plant), CGR (60-90 DAS) (7.57g/m²/day), RGR (60-90 DAS) (0.017g/g/day).
