RESUMEN
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.
RESUMEN
India is the second- largest producer of rice in the world, with 43.86 million hectares of land under rice cultivation where the crop residue generated is more than 160 million tons per year. The rice straw management is a challenging task in rice-producing regions. So, there is a need for an effective waste disposal technology for converting this waste into some valuable form. Keeping this in view,the present investigation was undertaken during the winter (Rabi) season of 2021-22 and 2022-23 at the Research Farm of the KVK Jagdishpur, Sonipat, Department of Vegetable Science, CCS Haryana Agricultural University, Hisar, Haryana to evaluate the effect of rice straw management on the growth attributes of potato.The seed material of potatocv. “KufriKhyati” was grown with twelve different rice straw treatment combinations. The experimental results revealed that the treatment T1 (Removing of straw + Planting) which was at par with treatment T9 (Urea (50kg/ha) + WD (25lt/ha) + FYM (1ton/ha) + Mixing of chopped straw + Planting) performed superiorly over the other treatments with significantly higher values for growth attributes viz., plant emergence (%), plant height (cm), number of stems per hill and number of leaves per hill.
