Influence Of Fruit Positions And Fruit Retention Loads On Seed Yield And Seed Quality Of Okra

Abstract

In order to evaluate the influence of fruit positions and fruit retention loads on seed yield and seed quality of okra, an experiment was conducted in 2016 and 2017 at Vegetable Research Farm, Kalyanpur and Seed Testing Laboratory of Department of Seed Science and Technology by using Factorial Randomized Block Design and Factorial Complete Randomized Design respectively with three replications. The okra variety, Arka Anamika was tested with 12 treatment combinations (consisted of two fruit retention loads as factor I and six fruit positions as factor II). Observations were recorded on seed yield and yield contributing traits along with seed quality parameters and economic parameters. Results revealed the significant variation between factors and their levels. Significantly highest values for growth parameters, seed quality parameters and economic parameters were recorded in R1 (Retention of fruits borne on different nodes for seed purpose and harvesting remaining fruits for vegetable purpose) fruit retention load over R2 (Retaining all fruits) . Among the fruit positions, P1 (Collection of seeds from fruits borne on 1-3 nodes) position recorded significantly maximum values for most of the growth parameters, green fruit yield and seed quality parameters in both the years of experimentation and pooled data. Thus, it is concluded that treatment combination, R1P1 (Retention of fruits borne on 1-3 nodes for seed purpose and harvesting remaining fruits for vegetable purpose) was found to be superior for most of the yield contributing traits and seed quality parameters whereas, R1P6 (Retention of all fruits for seed purpose) was found to be superior for economic parameters. Finally, for harvesting the vigorous seed, the treatment combination R1P1 and for getting the highest B: C ratio, the treatment combination R1P6 may be adopted by the seed producer newline
