Impact of integrated nutrient management on the growth, yield, and quality of Okra (Abelmoschus esculentus L. Moench)

Abstract

The present investigation entitled Study of Integrated Nutrient Management on Growth, Yield and Quality of Okra [Abelmoschus esculentus (L.) Moench]" was conducted during Kharif season from July to November 2023 at College of Horticulture, Rama University, Kanpur. he experiment was laid out in Randomized Block Design with 10 treatments viz., T1-Control (No use of fertilizers), T2-100% Recommended dose of fertilizers (RDF), T3-75% RDF + 25%RDN through FYM + Azotobactor+ Phosphorus solubilizing bacteria [PSB], T4-50% RDF + 50% RDN through FYM, T5-75% RDF + 25% RDN through vermicompost + Azotobactor + Phosphorus solubilizing bacteria [PSB], T6-50% RDF + 50% RDN through vermicompost, T7-75% RDF + 12.5% RDN through FYM + 12.5% RDN through vermicompost + Azotobactor+ Phosphorus solubilizing bacteria [PSB], T8-50% RDF + 25% RDN through FYM + 25% RDN through vermicompost + Azotobactor + Phosphorus solubilizing bacteria [PSB], T9 -100% RDN through FYM and T10-100% RDN through vermicompost. These treatments were replicated thrice. The growth attributes were significantly affected due to the different INM treatments. Application of inorganic fertilizers in combination with organic manures and biofertilizers i.e. 75% RDF + 12.5% RDN through FYM + 12.5% RDN through vermicompost + Azotobactor+ Phosphorus solubilizing bacteria [PSB] recorded significantly higher plant height (25.16, 78.68, and 125.64 cm), number of leaves (11.54, 45.55 and 55.50), number of branches (0, 2.19 and 4.41) and inter nodal length (2.41, 5.47 and 6.95 cm) at 30, 60 and at final harvest respectively.
