Effect of bio-fertilizers and inorganic manures on growth, yield and quality of okra (Abelmoschus esculentus L. Moench) under Prayagraj Agro-climatic condition

Abstract

A field experiment was carried out to assess the “Effect of bio-fertilizers and inorganic manures on growth, yield and quality of Okra (Abelmoschus esculentus L. Moench) under Prayagraj Agro-climatic condition”. during kharif season, 2015 at Vegetable Research Field, Department of Horticulture, Sam Higginbottom University of Agriculture Technology and Sciences, Prayagraj (U.P.). Different levels and combination of bio-fertilizers and inorganic manures was applied to assess the vegetative growth, yield and quality characteristics of Okra cv. Kashi Pragati (VRO-6). The experiment was laid out in factorial randomized block design (FRBD) with sixteen treatments and three replications. Regarding the different parameters of growth, yield and quality; the treatment T12 (Azotobactor+PSB+NPK@100:50:50) differ significantly. viz. Higher number of nodes (27.60), diameter of stem (2.08cm), days taken to first flower appearance (38.07), Days taken to 50 % flowering (53.67), diameter of fresh fruit (1.44cm), average fruit length (14.13cm), average fruit weight (12.80g), number of fruit per plant (22.33), fruit yield per plant (285.87g), total yield of fruits (179.99 q/h), total seed yield per plant (24.2g), ascorbic acid (19.30mg/100g), TSS (14.970Brix), incidence of Y.V.M.V. (0.90%) and BC ratio except plant height (169.23cm) and number of leafs (33.90) which were observed the maximum in the treatment T16 (Azotobactor+PSB+NPK@120:60:60).
