Influence of plant spacing and fertilizer levels on growth and yield of summer groundnut

Abstract

A field experiment was conducted at Main Agricultural Station, Dharwad during summer 2017-18 under sprinkler irrigated condition to study the influence of plant spacing and fertilizer levels on summer groundnut. The experiment was laid out in split plot design consisting of three spacing in main plot (S1: 30cm × 10cm, S2: 30cm × 7.5cm and S3: 30cm × 5cm) and three fertilizer levels in subplot (F1: 100% RDF, F2: 125% RDF and F3: 150% RDF). The results indicated that, plant spacing did not differ significantly on pod yield. Similarly, Application of 125 per cent RDF (39.20 q ha-1) and 150 per cent RDF (38.08 q ha-1) did not differ significantly on pod yield, but was significantly higher than 100 per cent RDF (36.47 q ha-1). The combination of plant spacing of 30cm × 10cm with 125 per cent RDF recorded significantly higher pod yield as compared to other combination.
