Abstract
A two-year field experiment was carried out at experimental farm of BCKV, Nadia, West Bengal during kharif seasons of 2019–20 and 2020–21 to study the effect of combined application of coated urea and organic manure on performance of rice. The experiment was laid-out in a randomized complete block design with four replications and treatment comprised 5 treatment combinations, such as T1 , control plot (without N); T2 , 100% recommended dose of nitrogen (RDN) through neem-coated urea (NCU); T3 , 75% RDN through NCU + 25% RDN through FYM (farm yard manure); T4, 100% RDN through polymer sulphur coated urea (PSCU); T5, 75% RDN through PSCU+25% RDN through FYM. The results showed that 75% RDN through PSCU+25% RDN through FYM re- sulted in maximum growth attributes, viz. plant height (110.8 cm), maximum number of effective tillers per square meter (416/m2 ), highest dry-matter accumulation (DMA) (740 g/m2 ), leaf area index (LAI) (4.47) and crop growth rate (CGR) (6.56 g/m2 /day), highest yield components like panicle length (23.5 cm), panicle weight (9.95 g), num- ber of filled grains/panicle (113), test-weight (21.3 g) and maximum grain yield (4.79 t/ha) and straw yield (5.53 t/ ha). Similarly, maximum amount of total nutrient uptake by crop (99.7, 40.1 and 208 kg/ha NPK), protein yield (418 kg/ha), gross returns (` 71.8 × 103 /ha), net return (` 52 × 103 /ha) and B: C ratio (2.73) were noticed under T5 treat- ment. Therefore, it is advisable to implement a comprehensive nutrient management strategy T5 (75% RDN through PSCU + 25% RDN through FYM) in rice cultivation. This approach enhances growth, yield, nutrient absorption, and quality, ultimately boosting agricultural productivity, profitability, and sustainability.
