Enhancing Okra Growth and Yield Through Foliar Nutrient Application in Conjunction with Mulching and Drip Irrigation

Abstract

Background: Okra (Abelmoschus esculentus) is an important vegetable crop that belongs to family malvaceae and is grown both in tropical and subtropical regions of India. In north-coastal Andhra Pradesh, okra is cultivated frequently so, optimizing the nutrient management practice is an efficient method for increasing yield. Among those practices, foliar fertilizers, mulching and irrigation methods are essential in maximizing the yield and quality of okra. Therefore, the present investigation deals with the combined effects of foliar nutrients, mulching and irrigation methods, providing valuable data for sustainable okra production in a particular area. Methods: The present investigation was conducted during June to September 2023, with seven different treatments using randomized block design. This experiment mainly focuses on combinations of mulching and foliar sprays of 19:19:19 and 13:0:45 at different concentrations. Collected data were analyzed using ANOVA and fisher’s least significant difference test at a 5% significance level. Result: Among all the treatments, 100% RDF along with the foliar application of 19:19:19 @ 1.0% + 13:0:45 @ 2% at 30, 45 and 60 days after sowing has proven the best treatment, where it recorded the highest yield of 101 q per hectare (Q/ha) due to the application of sufficient nutrients. Whereas, the lowest yield was recorded with control plot due to insufficient nutrient supply in relation to growth and yield parameters.
