Climate change and intensive farming necessitate precise nutrient application in agriculture. Potassium, magnesium and sulphur deficiencies impact crop yield and quality, while agrochemical residues pose environmental risks. Mahalaabh (K₂SO₄·MgSO₄·6H₂O), a natural and neutral potassium Schoenite compound containing potassium, sulphur and magnesium, addresses these challenges. Field experiments were conducted during the 2023-24 Rabi season at AGROCEL Industries Pvt. Ltd., Mandvi, to ascertain the effects of Mahalaabh on wheat, mustard and onion using a Randomized Block Design with different application methods and dosages. Mahalaabh improved yields across all crops compared to the RFD and commercial check K-mag. In wheat, drip application at 8 kg/acre increased yield by 31.27%, while foliar application twice at 15 g/L improved yield by 18.10%, due to increased ear length and test weight. For mustard, two applications at 10 kg/acre yielded a 12.75% increase, primarily attributed to more secondary branches, siliqua/plant and seeds/siliqua, with two applications more effective than the single ones. In contrast, single applications of Mahalaabh at 12.5 kg/acre increased onion yields by 29.20% and were comparable to the results obtained from two applications at the same rate (30.97% increase).  Mahalaabh Powder proves effective for crop yield improvement, with optimal application methods and dosages varying by crop type.
