Abstract:
The experiment was carried out during Kharif seasons of 2014 and 2015 to study the ‘Soil health and productivity of groundnut (Arachis hypogaea L.) as influenced by integrated nutrient management under rainfed Alfisols’. During two consecutive years of study, supply of 100 per cent nitrogen through sheep penning (T₉) recorded significantly higher number of colony forming units of bacteria, fungi and actinomycetes over the rest of the nutrient management practices tried after harvesting of the groundnut, while it was lowest with control plot (T₁) both under rainfed and protective irrigated situations. Supply of 100 per cent of nitrogen through sheep penning (T₉) recorded significantly highest pod and haulm yield of groundnut, which was however comparable with 50 per cent nitrogen through urea + 50 per cent nitrogen through FYM (T₃) and recommended dose of fertilizer (T₂) under rainfed situation, but under protective irrigation, which was inturn comparable with supply of 50 per cent nitrogen through urea + 50 per cent nitrogen through leaf compost (T₅). Control (T₁) recorded the lowest pod and haulm yield in groundnut in both the situations during two consecutive years of investigation.
