Abstract:
An experiment was conducted during summer season of the year 2020 at Agronomy Instructional Farm, C. P. College of Agriculture, Sardarkrushinagar Dantiwada Agricultural University, Sardarkrushinagar to study the “Effect of potassium and sulphur on yield, quality and nutrient uptake by summer groundnut (Arachis hypogeal L.) In loamy sand”. Nine treatment combinations comprising three levels of potassium (0, 25 and 50 kg ha^-1) and three levels of sulphur (15, 30 and 45 kg ha^-1) were evaluated in randomized block design with factorial concept with three replications. An application of potassium @ 50 kg K₂O ha^-1 recorded significantly higher pod yield, haulm yield protein content, oil content in kernel; oil yield, total uptake of N, P, K and S by groundnut crop as compared to 0 kg K₂O ha^-1. Potassium availability was significantly increased with increasing levels of potassium. Among different sulphur levels, application of 45 kg S ha^-1 recorded significantly higher pod yield, haulm yield, protein content, oil content in kernel; oil yield, total uptake of N, P, K and S by groundnut crop as compared to 15 kg S ha^-1. An application of sulphur improved the available sulphur status in soil.
