DECOMPOSITION OF SUGARCANE HARVEST RESIDUE WITH DIFFERENT COMPOST CULTURESMOUNESHWARI R. KAMMAR, ARJUN R. SULAGITTI AND ANGADI S.C.Abstract This study was conducted by Krishi Vigyan Kendra, Bagalkot during 2020-21 and 2021-22 at Honnakatti village of Bagalkot and Mangalgudda village of Badami taluk respectively with ten sugarcane farmers. Three methods of trash decomposition were compared in this on farm testing. Farmers practice of retaining sugarcane trash/residue as technology option 1 (farmers practice), application of compost culture @ 6 kg /ac as technology option 2 (source: UAS Dharwad) and application of waste decomposer @200 lit/ac as technology option 3 (source: NCOF, Ghaziabad). The results of using three technological options (TO) over two years as on farm testing to decompose the sugarcane trash have been studied to study their impact. TO 1 being retention of Sugarcane trash, TO2 is application of compost culture @6kg/ac and TO3 is application of waste decomposer @200 l/ac. Among all the treatments it was found that, application of compost culture @ 6 kg /ac was proved to be better in enhancing organic carbon content of soil from 0.405 to 0.445, yield levels also increased from 100.57 to 110.7 t/ha, followed by use of waste decomposer and farmerâ |
