About 40-70% of conventional fertilizer is wasted due to leaching causing environmental issues. Controlled release fertilizers provide a promising solution as they gradually release nutrients to match the crop's nutrient requirements, improving nutrient uptake efficiency and reducing nutrient losses. The Experiment was carried out During March To June 2021-22, using a randomized block design with three replications and eight treatments, including a control using the recommended dose of fertilizer (RDF). The statistical analysis of the variance showed that the use of CRF had a significant effect on the growth, yield, and quality of red okra. Among the different levels of CRF used, treatment T7 (11g CRF/plant) performed the best in terms of growth parameters such as plant height and number of leaves. Treatment T2 (7g CRF/plant) was found to perform the best in terms of earliness parameters. Treatment T5 (9g CRF/plant) had the highest yield with 14.30 t/ha. Treatment T6 (10g CRF/plant) was found to be the best for quality parameters. The highest benefit-cost ratio was recorded in treatment T5 (9g CRF/plant) which is 4.7. From the present investigation, it is concluded that, CRF can be used efficiently for higher crop production.
