Abstract:
A study was carried out at changes in enzyme activities during composting which offers a promising solution for assessment of quality of compost during the year 2022 – 2023 at Dr. Balasaheb Sawant Konkan Krishi Vidyapeeth, Dapoli, Dist. Ratnagiri, Maharashtra. The experiment was laid out in Factorial Randomized Block Design (FRBD) with ten treatments and three replications using the leaf litters of Mango (Mangifera indica), Sapota (Manilkara zapota), Jackfruit (Artocarpus heterophyllus), and Cashew(Anacardium occidentale).In case of enzyme activity during composting, the Jackfruit leaf litter was found significantly superior with highest urease activity (312.00, 316.33, 322.00, 316.17 and 309.17 μg NH4+ N g-1 compost h-1), acid phosphatise activity (317.00, 322.17, 328.17, 321.33, and 311.50 μg PNP released g-1hr-1), alkaline phosphatase activity (622.33, 627.50, 632.83, 638.67 and 643.33 μg PNP released g-1hr-1) and dehydrogenase activity (52.00, 49.33, 46.17, 42.67 and 39.33 mg TPF g-1 hr-1) on 20, 40, 60, 90, and 120 days of composting respectively. The lowest of enzyme activities were observed in cashew leaf litter compost.Thus, during litter composting, the enzyme activities decreased with increasing the composting period.
