Assessing the Influence of Biostimulants on the Growth and Crop Yield of Okra (Abelmoschus esculentus)

Abstract

This study, carried out at "C" Block Farm, Bidhan Chandra Krishi Viswavidyalaya, Kalyani, Nadia, West Bengal, during the 2022–23 period, to find out the impact of biostimulants on the growth and yield of Okra (Abelmoschus esculentus). The primary goals include examining the significant effects of biostimulants and determining the optimal dosage of the biostimulant, aligning with the growing emphasis on sustainable agricultural practices. The farm, situated near the Tropic of Cancer, exhibits coordinates of approximately 22.89°N latitude and 88.45°E longitude, with an altitude of around 9.75 m above sea level. The experimental design utilized a Randomized Block Design (RBD) with three replications and five treatments. Results highlight that the growth and yield parameters of Okra were notably influenced by the foliar application of modulin. Specifically, applying 2.5 kg ha-1 of Modulin spray at 25 & 40 days after sowing (DAS) along with 100% NPK demonstrated to be economically rewarding and advantageous for achieving a higher yield of Okra."
