ABSTRACT
Optimizing mineral nutrition is crucial to boosting groundnut output since groundnut have a high nutritional requirement and the recently released high yielding varieties further absorb nutrients from the soil. On the other hand, farmers that grow groundnut sometimes employ only one or two nutrient-rich fertilizers, which results in severe mineral deficits. One of the primary reasons for low groundnut productivity is inadequate and imbalanced nutrient usage. At the Oilseeds Research Unit, Dr. Panjabrao Deshmukh Krishi Vidyapeeth, Akola, Maharashtra, India, a field experiment was carried out in the summer to assess the effects of organic, inorganic, and foliar grade fertilizers on the growth and yield of groundnut. The integration of organic, inorganic, and foliar grade fertilizers considerably improves growth and yield qualities, according to experimental data. The findings showed that the application of FYM @ 7.5 t ha-1+100% RDF 25:75:25 NPK kg ha-1 considerably improved plant growth parameters, such as plant height and yield attributes yield. Starter dose (11:36:24 NPK + trace element) + booster dose (8:16:39 NPK + trace elements) applied topically. It was determined that integration of organic (7.5 t ha-1), inorganic fertilizer (100% RDF), and water soluble grade fertilizer recorded, highest dry pods yield and getting maximum economic return from summer groundnut. This treatment was closely followed by treatment FYM @ 7.5 t ha-1+100 % RDNPK, which recorded significant pod yield (27.18 qt ha-1), net monetary return (79464 Rs. ha-1) and benefit: cost ratio (2.77).
