Abstract: A field experiment was carried out to investigate the “Effect of Integrated Nutrient Management on Growth, Yield and Quality of Okra (Abelmoschus esculentus L. Moench). During February to July 2023 at Vegetable Research Field, Department of Horticulture, Sam Higginbottom University of Agriculture Technology and Sciences, Prayagraj (U.P.). Different combination of organic and inorganic fertilizers with different cultivars of okra such as TMOH 2366, Okra 2361, Okra TMOH 375, okra check variety Samrat was incorporated to assess the vegetative growth, yield and Quality characteristics of Okra. The experiment was laid out in factorial randomized block design (FRBD) with sixteen treatment combinations viz T1 (control + TMOH 2366), T2 (FYM-15 t/ha + TMOH 2366), T3 (NPK-50% + FYM-15 t/ha + V.C.-5 t/ha + TMOH 2366), T4 (NPK-50% + FYM-10 t/ha + V.C.-2.5 t/ha + TMOH 2366), T5 (control + Okra 2361), T6 (FYM-15 t/ha + Okra 2361), T7 (NPK-50% + FYM-15 t/ha + V.C.-5 t/ha + Okra 2361), T8 (NPK-50% + FYM-10 t/ha + V.C.-2.5 t/ha + Okra 2361), T9 (control + Okra TMOH 375), T10 (FYM-15 t/ha + Okra TMOH 375), T11 (NPK-50% + FYM-15 t/ha + V.C.-5 t/ha + Okra TMOH 375), T12 (NPK-50% + FYM-10 t/ha + V.C.-2.5 t/ha + Okra TMOH 375), T13 (control + okra check variety Samrat), T14 (FYM-15 t/ha + okra check variety Samrat), T15 (NPK-50% + FYM-15 t/ha + V.C.-5 t/ha + okra check variety Samrat), T16 (NPK-50% + FYM-10 t/ha + V.C.-2.5 t/ha + okra check variety Samrat) and three replications. The data analysis revealed that treatment T11 (NPK-50% + FYM-15 t/ha + V.C.-5 t/ha + TMOH 375) showed superior performance as compared to other treatments in numerous growth parameters, such as the minimum number of days to germination (9.13), maximum germination percentage (82.70%), plant height (92.46 cm), seedling root length (10.47 cm), shoot length (21.57 cm) and seedling length (32.03 cm). Besides, the T11 treatment also showed best results in terms of pod width (4.45 cm), pod length (14.30 cm), yield per plant (143.56 g), and yield per hectare (26.58 t) as yield characteristics. Furthermore, T11 exhibited higher levels of TSS (3.660Brix) and vitamin C content (18.69 mg) as quality attributes. On the other hand, treatment T1 (control + TMOH 2366) showed the lowest response in terms of growth, yield, and quality.
