Abstract: An experiment was conducted to study the nutrient use efficiency of nutrient enriched biochar (NEB) from sugar industry wastes with seven treatments comprising T1 (absolute control), T2 (50% RD of PK through NEB), T3 (75% RD of PK through NEB), T4 (100% RD of PK through NEB), T5 (125% RD of PK through NEB), T6 (50% through NEB + 50% through inorganic fertilizer) and T7 (100% RD of PK through inorganic fertilizer) in RBD using the rice variety TRY 3 at Anbhil Dharmalingam Agricultural College and Research Institute, Trichy District, Tamil Nadu. In all treatments, nitrogen was supplied based on LCC reading. The result of the field experiment revealed that application of NPK through NEB favourably influenced the yield contributing parameters viz., number of tillers per hill, productive tillers per hill, length of panicle, number of filled grains per panicle which will release the nutrients slowly and steadily to maintain the availability of nutrients throughout the crop period thereby increasing the nutrient use efficiency and crop yield. Since the yield of T3 treatment (6103 kgha-1) was on par with T4 (6165 kgha-1) and T5 (6269 kgha-1) treatments, which indicated that the plants received the essential nutrients in required quantities at 75% RD of PK through NEB itself. On optimization of graded levels of NEB, the application of 75% RD of Pk through NEB was found to be the best treatment with respect to nutrient use efficiency and grain yield in response to the quantity of nutrient applied.
