Abstract
India is demand for vegetable oils is escalating rapidly, yet domestic production struggles to keep pace. Groundnut (Arachis hypogaea L.), most important oilseed crops pre-dominantly growing, often exhibits low yield due to inadequate nutrient management. A field trial was conducted during late rabi season (2024-2025) at SRMCAS, Baburayanpettai, Tamil Nadu, India. The study was investigated a randomized block design with ten treatments combining varying levels of 100% RDF along with gypsum @ 50% basal and 50% at 25, 35 and 45 DAS and 75% RDF along with gypsum @ 50% basal and 50% at 25, 35 and 45 DAS. The groundnut variety GG 7 was used. Growth and yield parameters were measured at 25, 50 and 75 days after sowing and at harvest. The study revealed that the combined application of 100% RDF along with gypsum @ 50% basal and 50% at 45 DAS and 75% RDF along with gypsum @ 50% basal and 50% at 45 DAS significantly increased plant height, DMP, LAI, total chlorophyll index, number of root nodules, number of flowers, pegs, pods per plant and kernels per pod. This treatment was also recorded higher pod yield (2100 and 2031 kg/ha) and haulm yield (5097 and 4952 kg/ha). The study of groundnut crop analysis gives a clear understanding of the nutrient accumulation at different stages of growth of groundnut and this can be utilized for fertilizer supply during critical stages and timely gypsum application ensures the adequate calcium and sulphur availability at peg formation and pod development stage cause micro acidification of soils which slightly lower down the pH of soil and rises the nutrient availability.
