Influence of Organic and Inorganic Sources of Nutrients and Their Methods of Application on Growth and Yield Attributes of Groundnut (Arachis Hypogeae L.)

A field experiment carried out to investigate the influence of organic and inorganic sources of nutrients and their methods of application on groundnut (Arachis hypogeae L) revealed that growth and yield attributes as well as yield improvement could be obtained by root zone placement of manures and fertilizers mainly through a significant improvement in 100 kernel weight. Organic manure (FYM) and different levels of NPK through fertilizers were applied as broadcasting and root zone placement in various treatments. Thirteen tonnes of FYM application per hectare recorded significantly higher yield as compared to control. Basal application of 75% recommended dose of fertiliser [RDF: 20-80-20 (NPK) kg/ha] applied in root zone produced higher dry matter accumulation and nut yield. Amongst the interaction effects, combination of 13t FYM + 75% RDF, 13t FYM + root zone application and 100% RDF + root zone application recorded the highest nut yield of groundnut as compared to other treatment combinations.
