Abstract

The need for precise nutrient application has become crucial in agriculture due to climate change and intensive farming practices. Deficiencies in potassium, magnesium and sulphur are critical for enhancing both crop yield and quality. Additionally, agrochemical residues in soil, water and farm products pose significant challenges. Mahalaabh (K2SO4·MgSO4·6H2O), a combination of potassium, sulphur and magnesium, offers a balanced solution to address these issues. Field experiments were conducted during the Kharif season of 2023-24 at Agrocel Industries Pvt. Ltd., Kachchh, to evaluate the impact of Mahalaabh on castor, cotton and groundnut crops. The trials were executed in a Randomized Block Design, testing different doses of Mahalaabh powder through foliar spray, fertigation and granular soil application. The results demonstrated that Mahalaabh powder is effective in enhancing productivity across the tested crops. In castor, higher doses of 10 kg/acre through drip irrigation and 20g/L foliar application increased productivity by 22.3% and 14.3% over the recommended fertilizer dose (RFD), respectively. However, in cotton, lower doses of 6kg/acre through drip irrigation and 10g/L through foliar application were more effective, resulting in 3.8% and 5.3% yield enhancements compared to RFD. In groundnut, foliar spray at 15 g/L applied thrice at 30-35, 50-55, and 70-75 days after sowing (DAS) was effective, resulting in a 22.9% higher pod yield compared to RFD. These findings highlight the importance of balanced nutrient management practices tailored to specific crop requirements for achieving optimal agricultural productivity.
