Performance of Direct Seeded Rice under Integrated Nutrient Management Practices in Old Alluvial Soi
A field experiment was conducted during Kharif 2018-19 and 2019-20 at the farm of Regional Research station, Old Alluvial Zone, Uttar Banga Krishi Viswavidyalaya, Majhian, Dakshin Dinajpur, West Bengal to study the Performance of direct seeded rice (var. GB-1) under integrated nutrient practices. Highest number of effective tillers plant-1 (17.81), panicle length (29.56 cm) and number of filled grains panicle-1 (262.15) as well as seed yield (3051.89 kg ha-1) have been observed where direct seed rice crop received 75% of the recommended dose of fertilizers, FYM @ 5ton ha-1 and brown manuring with dhaincha. Highest number of effective tillers plant-1 (18.86), panicle length (28.89 cm) and number of filled grains panicle-1 (260.54) and seed yield (3079.92 kg ha-1) have also been observed with spraying of Vermiwash and N-P-K 19:19:19 at 35 DAS and 55 DAS respectively to the direct seeded rice crop. An increasing trend in residual fertility status has also been observed with this treatment compared to the initial fertility status of the soil. This treatment can be an acceptable option of integrated nutrient management practice for the direct seeded rice growers of the old alluvial zone.
