Abstract:
An present field experimental trial was conducted to assess the Effect of potassium and sulphur on total uptake and availability of nutrient under summer groundnut during summer season of 2018 at the RCSM College of Agriculture, Kolhapur (M.S.), India. The field trial was laid out in FRBD with three replications and twelve treatment combinations. The soil of experimental field was sandy loam in texture, low in available nitrogen (238.84 kg ha^-1), moderately high in available phosphorus (23.65 kg ha^-1) and moderately high in available potassium (249.10 kg ha^-1). The soil was slightly alkaline in reaction (pH 7.7). The mean N, P, K, S uptake of groundnut and available soil N, P, K, S were recorded maximum with application of 45 kg K₂O ha^-1 followed by 30 kg K₂O ha^-1 in case of potassium and 40 kg S ha^-1 which is comparable with 20 kg S ha^-1 in case of sulphur.
