Effect of Nano Zinc and Nano Calcium on Growth, Yield, Soil Nutrient Status and Economics of Groundnut (Arachis hypogaea L.) under Rainfed Conditions of the Central Dry Zone of Karnataka, India

A. H. Kumar Naik, H. Varsha, T. N. Usha & S. E. Bhumika · Journal of Experimental Agriculture International · 2026

Groundnut (Arachis hypogaea L.) is one of the most important oilseed crops cultivated under rainfed conditions, where micronutrient deficiencies, particularly zinc and calcium, frequently limit crop productivity. Nano-fertilisers have emerged as efficient nutrient delivery system...
