Nutrient release pattern of organo-mineral fertilizers in Southern laterites of Kerala


Ganesh S, Nishan MA, Shalini Pillai P, Atul Jayapal and Gowripriya

The study was conducted at the Department of Agronomy, College of Agriculture, Vellayani, Kerala Agricultural University, during Rabi 2023-2024. It focused on formulating two organo-mineral fertilizers (OMF 1 and OMF 2) suited for Sesamum and evaluating its nutrient release patterns. The experiment utilized a completely randomized block design with four treatments and four replications for each treatment. The treatments were:- T1 (100% recommended dose of nutrients (RDN) as OMF 1), T2 (100% RDN as OMF 2), T3 (100% RDN as per Kerala Agricultural University Package of Practices, and T4 (Control). At 15 days after incubation (DAI), T3 (conventional fertilizer) demonstrated significantly higher nutrient release, with 89.99% of applied nitrogen, 80% of phosphorus, and 89.85% of potassium released. In contrast, OMF 1 and OMF 2 exhibited a slower nutrient release, with nitrogen release ranging from 53.18% to 53.22%, phosphorus from 45.65% to 50%, and potassium from 40.40% to 43.23%. At 30 days after incubation, nutrient release remained higher for T3. However, at 45, 60, 75, and 90 days after incubation, OMF 1 and OMF 2 outperformed T3, showing a more sustained and gradual release of nutrients over time. This study underscores the potential of organo-mineral fertilizers to provide a controlled and prolonged nutrient supply, enhancing nutrient use efficiency and supporting long-term soil fertility in sesamum cultivation.
