Response of Integrated Nutrient Management on Growth and Yield Characteristics of Okra

Abstract

The present investigation entitled “Response of integrated nutrient management on growth and yield characteristics of okra” was conducted at the Horticultural Research Farm, Sardar Patel University, Balaghat (M. P.) in Rabi Season of 2021. In this investigation eight treatments used with control, data pertaining to various criteria used for treatment evaluation were analyzed statistically, the treatments details are T1- Control (No NPK), T2- (100% RDF), T3-(75% RDF + 25% Azospirillum), T4-(50% RDF + 50% FYM), T5- (50% RDF + 50% Vermicompost), T6- (50% RDF + 25% Azospirillum + 25% FYM), T7- (50% RDF + 25% Azospirillum + 25% Vermicompost) and T8 - (50% RDF + 25% FYM + 25% Vermicompost). The experiment was laid out on Randomized Block Design with three replications. The observation of growth and yield of okra crop i.e. Plant height (cm) 30 and 60 DAS, Number of leaves per plant 30 and 60 DAS, Number of branches per plant at 60 DAS, Number of internodes per plant, length of internodes, Number of fruits per plant, Fruit length (cm), Weight of fruit per plant (g) and Fruit yield per hectare (q). The result revealed that the outstanding performance was estimated from the treatment no 7 i.e. 50% RDF + 25% Azospirillum + 25% Vermicompost, from which maximum estimates were observed for most of the traits viz. Plant height (cm) 30 and 60 DAS (21.88 cm and 62.07cm), Number of leaves per plant 30 and 60 DAS (5.60 and 15.58), Number of branches per plant at 60 DAS (6.66), Number of internodes per plant (20.31), length of internodes (9.11 cm), Number of fruits per plant (13.13), Fruit length (16.21cm), Weight of fruit per plant (367.85 g) and Fruit yield per hectare (165.53 q/ha), while the minimum value of all parameters was found under control. From the investigation it has been concluded that combined application of 50% RDF + 25% Azospirillum + 25% Vermicompost was responsible for best results for various growth and yield parameters of okra.
