(Arachis hypogeae L.) as Affected by Sulphur and Planting Methods in Course Textured Soil of South-west Haryana, India

Abstract

The groundnut, scientifically known as Arachis hypogea L., is a summer legume plant with rising importance in food, industry, and medicine. Sulphur is the master nutrient for oil seed crop production because it helps in the synthesis of cysteine, methionine, vitamins (B, biotin, and thiamine), metabolism of carbohydrates, oil content, protein content and also associated with growth and metabolism. The experiment was laid out in randomized complete block design in triplications on groundnut cultivar GNH 804 in Bawal utilizing three sulphur levels (0, 25, and 50 kg/ha) and three planting methods (flatbed, flatbed with earthing up, and ridge-furrow). The treatment with 50 kg/ha sulphur in the ridge-furrow method yielded the highest pod yield (2652 kg/ha) and superior nutrient content, including nitrogen, phosphorus, potassium, and sulphur, in both seeds and stover. This treatment also showed superior quality parameters such as oil and protein content and shelling percentage for groundnut. The treatment with 50 kg/ha of sulphur and the flatbed with earthing up method followed closely in performance.
