Although using inorganic fertilizer enhances the amount of nutrients in the crops, it also lowers the quality of the produce. As a result, adding organic nutrients to the soil to promote crop growth can enhance crop quality. Farmyard manure is a potential natural nitrogen source for indirectly increasing soil fertility and crop output directly. To determine the effects of farm yard manure, NPK 19:19:19 fertilizer, and a combination of farm yard manure and NPK 19:19:19 fertilizer on the growth and yield of okra (Abelmoschus esculentus L) vegetable, field tests were carried out in 2020 and 2021. With 24 plots spaced 45 × 30 cm apart, the total planted area was roughly 5 cents. Using the Random Block Design, six distinct treatment combinations were experimentally evaluated. The combination of farm yard manure (50%) and NPK 19:19:19 (50%) resulted in the highest okra growth and production in 2020 and 2021 compared to alternative treatment alternatives. Additionally, for the same treatment, the growth and yield of okra increased higher in 2021 than in 2020, which resulted from the application of FYM and NPK, which increased the amount of organic matter and minerals in the soil. According to the study, combining FYM with NPK could be a sustainable and environmentally responsible strategy to improve crop quality in growth and production

FYM, Growth Parameters, NPK, Okra, Yield Parameters

According to the current study, the okra crop grows and develops more quickly when 50% NPK and 50% FYM are applied in the years 2020 and 2021. However, the yield and growth of the okra crop were higher in the year 2021 than they were in the preceding years. The increased development and production for the next year, 2021, will result from the higher soil nitrogen uptake brought on by the FYM and NPK applications done in 2020. The NPK fertilizers would lead to enhanced vegetative growth in terms of the number of leaves when the okra is first growing and in its intermediate stage of development. In contrast, slow-releasing nutrients from FYM would promote okra's growth during the flowering period. Thus, it can be concluded from the study that, in comparison to the single application of chemical and organic fertilizers, the optimal combination of FYM and NPK promotes greater growth and yield during the same crop length period
