Effect of Paddy Straw Incorporation on Growth and Yield of Rice under Wetland Ecosystem

Burning the paddy straw had variety of effects both on and off the farm. It entails nutrient and economic productivity loss in addition to impact on air quality, animal and human health. Soil incorporation is a cost-effective method of disposing the paddy straw. Effects of enhanced paddy straw incorporation in the field to investigate the growth and yield parameters during the summer season at TNAU, Coimbatore. The treatments comprise Continuous flooding (Conventional) (M1), AWDI (field water tube): Irrigation at soil moisture depletion by 10 cm (M2), AWDI (field water tube): Irrigation at soil moisture depletion by 15 cm (M3) as main plots. The subplot treatments consist of Rice raw straw incorporation + 75% RDF (S1), Rice raw straw incorporation with Pusa Decomposer Capsules + 75% RDF (S2), Rice raw straw incorporation with TNAU Bio mineralizer + 75% RDF (S3), Rice raw straw incorporation with Pusa Decomposer Capsules + TNAU Bio mineralizer + 75% RDF (S4), 75% RDF (S5), 100% RDF (S6). Incorporation of rice straw, Pusa decomposer, TNAU Bio-mineralizer along with 75% RDF recorded better results in all growth stages and yield.
