Role of Soil Amendments in Improving Groundnut Productivity of Acid Lateritic Soils

摘要

The present field experiment was conducted in sandy loam acid lateritic soil to study the effect of Fly Ash (FA), organic wastes like farmyard manure (FYM), vermicompost (VC) and green manure (Sesbania rostrata) (GM) and chemical fertilizers on growthand yield of groundnut during rainy season. A uniform fertilizer dose of20:40:40 kg N:P:K ha-1 was maintained through CF alone or through CF+organic wastes by supplementing 50% of N dose. Nine treatment combinations were tested under completely randomized block design. Application of organic wastes in combination with CF recorded better growth and yield as compared to sole application of CF. Among three organic sources of nutrients GM showed superior performance of the crop over FYM and VC. Integratedapplication of FA, organic wastes and chemical fertilizers increased the pod yield to the extent of 24.7% over sole application of CF.
