Abstract:
The field experiment was entitled “Effect of spacing and organic manures on growth and yield of kharif groundnut (Arachis hypogea L.)” conducted during Kharif 2021. Department of Agronomy, SHUATS, Prayagraj (U.P). The treatment consisted of spacing (30 × 10 cm, 35 × 10 cm, 40 × 10 cm) and organic manures (2.5t/ha vermicompost, 2t/ha farm yard manure, 1.5t/ha vermicompost + 1.5t/ha farm yard manure) viz. whose effect is observed on groundnut (var. Kadiri 1812). The experiment was laid out in Randomized Block Design, nine treatments replicated thrice. Plant height (62.91 cm), number of nodules (92.00), dry weight (53.69 g/plant), No. of pods/plant (23.53), no. of kernels/pod (2.00), harvest index (51.62%), kernel yield (2917.33 kg/ha), haulm yield (2698 kg/ha) were significantly influenced with treatment combination of 35 × 10 cm spacing + 2.5t/ha vermicompost. Maximum CGR (31.10 g/m²/day) were recorded with application of 30 × 10 cm spacing + 2.5t/ha vermicompost. However, RGR and seed index were found to be non- significant. Therefore, treatment combination of 35 × 10 cm spacing + 2.5t/ha vermicompost was most productive and cost effective.
