Respon Pertumbuhan dan Hasil Dua Varietas Tanaman Kedelai (Glycine Max L.) Terhadap Cekaman Kekeringan

Abstract

Drought stress is one the main constraints to plant growth. Drought stress can hinder plant growth from the early stages, and if it occurs throughout the plant growth period, it can disrupt metabolic processes and cause permanent tissue damage, preveting the plant from recovering. Effort to address drought stress is by promoting cultiyating varietas the are tolerant to drought stress. This research aims to determine two soybean varieties’ growth and yield responses to drought stress. The research was conducted in Bulotalangi Timur Village, Bulango Timur Subdistrict, Bone Bolango Regency, Gorontalo Province, from October to Desember 2022. This research employs a Randomized Complete Block Design (RCBD) factorial design consisting of two factors. The first factor was soybean varietas, which included two levels: Agromulyo and Wilis Variety. The second factor was drought stress, which consisted of three levels: Control (irrigation until harvest), No irrigation at 35-46 DAP (Days After Planting), and No irrigation at 42-53 DAP. The data were analyzed using analysis of variance (ANOVA) with a significance level of 5%. The results indicate that the two soybean varieties responded differently in terms of growth and yield. The Agromulyo variety has greater drought stress tolerance than the Wilis variety. The growth and yield of both soybean varieties were hindered under the drought stress condition applied during the 35-46 days after planting (DAP) period.
