Abstract:

A field experiment was conducted during the kharif season of 2025 at the Agricultural Farm of Himalayan University, Jollang, Itanagar, to evaluate the synergistic effects of slow- release fertilizers and Mahua oil cake on the growth of Chakhao black rice (Oryza sativa L.). The experiment was laid out in a Randomized Block Design (RBD) with three replications and eight treatments, viz., T1 (control), T2 (100% Recommended Dose of Nitrogen (RDN) through Neem Coated Urea (NCU) +25% Mahua oil cake), T3 (75% RDN through NCU + 25% Mahua oil cake), T4 (50% Recommended Dose of Nitrogen (RDN) through Neem Coated Urea (NCU) +25% Mahua oil cake), T5 (100% Recommended Dose of Nitrogen through rock phosphate + 25% Mahua oil cake), T6 (75% Recommended Dose of Nitrogen through rock phosphste +25% of mahua oil cake), T7 (50% Recommended Dose of Nitrogen through rock phosphate +25 % mahua oil cake), T8 (100% Recommended Dose of Nitrogen through neem coated urea +100% RDN through rock phosphate + 25% of mahua oil cake). The study recorded Significant differences among treatments were observed in plant height, leaf length, number of tillers, dry weight and leaf width of plant at 30, 60 and 90 days after transplanting (DAT). The results revealed that treatment T4 (50% RDN through Neem coated urea + 25% of Mahua oil cake) recorded the highest values for all growth parameters. This was followed by treatment T5, which received (100% RDN through rock phosphate + 25% Mahua oil cake).The lowest values were observed in the control (T1), which did not receive any additional nutrient inputs.
