Effect of Integrated Nutrient Management (INM) on Growth, Yield and Quality of Okra (Abelmoschus esculentus L.) cv. ‘Arka Anamika’

Abstract

The present investigation was carried out at Agricultural Research Farm, Department of Horticulture, S.G.V.U., Jaipur (Rajasthan) to study the effect of INM on growth, yield and quality of Okra (Abelmoschus esculentus L.) cv. ‘Arka Anamika’ during Rabi season of the year 2022-23. The experiment was laid down in RBD which consisted 9 treatment combinations viz; Control (T0), 100% RDF (T1), 100% RDF + Vermicompost @5t/ha (T2), 100% RDF + Poultry manure @2t/ha (T3), 100% RDF + Neem cake @2t/ha (T4), 50% RDF + Vermicompost @5t/ha (T5), 50% RDF + Poultry Manure @2t/ha (T6), 50% RDF + Neem cake @2t/ha (T7), 50% RDF + Vermicompost @5t/ha + Poultry Manure @2t/ha + Neem cake @2t/ha (T8) and treatments were replicated three times. Appraisal of the result indicated that the influence of organic and inorganic fertilizers on important parameters like vegetative growth, yield and quality of Okra were significantly influenced by INM under local agro climatic conditions. The treatment (T8) had a significant effect on various vegetative growth, yield and quality parameters, and the results revealed that the maximum plant height plant height at 30, 60 and 90 DAS, leaves per plant, days taken to 50% flowering, flowers per plant, fruit length, fruit diameter, fruit per plant, fruit yield, TSS, Ascorbic acid and Titrable Acidity (%) were recorded in T8. The minimum values of growth, yield and quality parameters were recorded in the control (T0). Results further indicated that the highest (3.06) benefit: cost ratio was observed in T8. Whereas, the lowest benefit: cost ratio (1.07) was recorded under control.
