Study on the effect of gibberellic acid and maleic hydrazide on growth and yield attributing characters of okra (Abelmoschus esculentus (L.) Moench) cv. Varsha Uphar

Abstract

A field experiment was conducted at Horticulture Research Farm, Department of Horticulture, RAK College of Agriculture Sehore during Kharif season of 2012-13. The experiment was laid out in Randomized Complete Block Design with three replications. Combination of gibberellic acid and maleic hydrazide, treatment T9 (100 ppm MH + 60 ppm GA3) was found significantly superior as compared to other treatments. Highest morphological characters (viz., plant height, number of leaves per plant, number of branches per plant, stem girth per plant and leaf area index) and yield attributes (viz., no of fruits per plant, fruit yield/plant and fruit yield /ha) were recorded in T9 (100 ppm MH + 60 ppm GA3). Maximum fruit yield of 125.29 q/ha obtained in treatment T9 but maximum net return of Rs 88698 /ha and cost benefit ratio of 1:3.52 was observed in treatment T8 (100ppm MH+ 40 ppm GA3).
