The growing demand for high-quality rice and rice products is motivating farmers to cultivate traditional rice varieties. To meet this demand, rice production must increase significantly, which requires effective nutrient management practices. Therefore, this study was conducted to assess the impact of integrated nutrient management practices on the growth, root morphology, yield parameters and overall yield of improved black Kavuni rice during the Early Kar season (April - August 2023) and Late Samba season (September - January, 2023-24). The experiment followed a Randomized Block Design (RBD) with 12 treatments and 3 replications. Based on nitrogen (N) equivalence, appropriate amounts of inorganic fertilizers, farmyard manure (FYM), vermicompost (VC) and poultry manure (PM) were applied. Data on plant growth, root morphology, yield parameters and yield were recorded and analysed using LSD at a 5 % significance level. The results indicated that the treatment involving 50 % of the recommended nitrogen dose (RDN) from inorganic fertilizer, 50 % from vermicompost and foliar sprays of 0.5 % ZnSO? and 1 % FeSO? at the tillering, panicle initiation (PI) and flowering stages (T11) produced significantly better growth, root morphology and yield parameters. This treatment was statistically on par with the treatment involving 50 % RDN from inorganic fertilizer, 50 % from vermicompost and foliar sprays of 0.5 % ZnSO? and 1 % FeSO? at the tillering and panicle initiation stages (T8).
