Nutrient Management in Groundnut

Abstract

Being a leguminous, groundnut is capable to meet out nitrogen requirement through biological nitrogen fixation, but application of basal dose is crucial for initial growth and development. Proper supply of phosphorus is important for root development. Calcium is important for pod formation while sulphur is required for oil synthesis. Groundnut is also sensitive to micronutrient deficiencies. Groundnut is an exhaustive crop and requires large amount of macro and micro-nutrients from the soil which cannot be met by single nutrient source. Under such condition supply of nutrients through organic and inorganic sources and biofertilizers in integrated manner is a feasible option; hence, there is ample scope for increasing groundnut production through nutrient management approach.
