Title : Effect of Different Decomposer Application in Shredded Trashes and Raw Trashes Composting and its Influence on Soil Nutrients and Productivity of Sugarcane in Alfisols of Tiruchirappalli District

Abstract :

Sugarcane cultivation is proud to the farming community as its useful in the production of high-value products. In addition, it produces voluminous trash which is nutrient-rich biomass. Burning of sugarcane trash has caused health-related issues as well as acted as an important factor in global warming. The aim of this study was to convert trashes into compost by degrading it through microbial inoculants. The study consists of three treatments, PUSA decomposer (4 capsules/tone of trash), TNAU Biomineralizer (2kg/tone of trash) and Cow dung slurry (5%) with shredded trashes and raw trashes. A more sugarcane cane yield of 87.2tha-1 was recorded in PUSA decomposer treated plot and it was 7.12 % over the control plot (81.4 kgha-1). More microbial population in the surface layer was 19.96 x106/g, 8.36 x103/g and 6.99x103/g of bacteria, fungi and actinomycetes respectively in the PUSA decomposer applied treatment in shredded trashes followed in TNAU Biomineralizer with raw trashes applied plot (19.63(x106/g), 8.30 (x103/g) and 6.74(x103/g) respectively) when compared to control. Further, use of implements like shredder helps in rapid decomposition and eventually increases the soil nutrient stages. The results shows that, in-situ sugarcane trash composting has increased the organic carbon, available nitrogen, available phosphorus and available potassium content in soil from 0.34 to 0.0.39%, 228.7 to 268.2 kgha-1, 7.80 to 9.91kgha-1 and 354.0 to 394.5 kgha-1 respectively. Therefore, in-situ composting with efficient decomposers like PUSA decomposers and TNAU Biomineralizer can be a good alternate to mitigate these problems.
