Effect of Different Organic Manures on Green Fruit Production in Okra (Abelmoschus esculentus L.)

Aims: The single and amalgamated effect of different doses of organic manures viz., Farm Yard Manure (FYM), Vermicompost and Enriched compost alone or in combination with Microbial consortia were studied in the present investigation to analyse their effect on the growth characteristics and fruit yield of Okra. Study Design: The experiment was laid out in Randomised Block Design (RBD) with three replications. Place and Duration of Study: The experiment was conducted during 2022 in the Organic Block of Experimental Farm, Department of Horticulture, Assam Agricultural University, Jorhat, Assam. Methodology: The different treatment combinations such as FYM 10 t/ha (T1), FYM 5 t/ha (T2), FYM 2.5 t/ha + Microbial consortia (T3), Vermicompost 5.0 t/ha (T4), Vermicompost 2.5 t/ha (T5), Vermicompost 2 t/ha + Microbial consortia (T6), Enriched compost 2.0 t/ha (T7) and untreated control (T8) were applied at the time of final land preparation. Results: The fruit yield parameters such as fruit weight (14.60 g), fruit volume (18.03 cc), fruit yield per plant (202.93 g) and total yield (95.74 q/ha) were maximum under T7 (Enriched compost 2.0 t/ha). However, the highest net return from tender fruits was produced with application of Vermicompost 2 t/ha + Microbial consortia (T6) leading to the maximum Benefit: Cost ratio of 3.80. Conclusion: Thus, it can be concluded from the present experimental analysis that fruit yield parameters were significantly enhanced by Enriched Compost 2 t/ha (T7) but was not statistically superior to Vermicompost 2 t/ha + microbial Consortia (T6) which proved to be the most remunerative for tender fruit production.
