Morphological Characteristics of Leaf Color and Leaf Shape of Soybean Variety Anjasmoro (Glycine max (L.) Merril) under Water Stress
Abstract
Anjasmoro soybean variety exhibits intolerance to water stress, which can significantly impact the growth of soybean plants, particularly concerning leaf morphological characteristics. This study aims to assess the effects of water stress on the leaf color and leaf shape of the Anjasmoro soybean variety. The research was conducted from June to July 2024 at the Gauze House of Food Crop Agribusiness at SMKN 1 Tambusai, Rokan Hulu, and the Integrated Laboratory of the Agrotechnology Study Program at the Faculty of Agriculture, Pasir Pengaraian University. The materials utilized in this study included Anjasmoro soybean seeds, soil, 35 x 40 cm polybags, and 15 kg of goat manure. This investigation employed a Non-Factorial, Completely Randomized Design (CRD), focusing on the variable of water stress (P) with three replications. The water stress treatments consisted of four levels: P0: 25% field capacity (KL) water stress applied twice daily, P1: 25% KL water stress applied twice daily, P2: 25% KL water stress applied once every three days, and P3: 25% KL water stress applied once every six days. The results indicated that water stress did not significantly affect the leaf color and leaf shape of the Anjasmoro soybean variety in the P0, P1, and P2 treatments. However, the P3 treatment resulted in observable leaf color and shape changes. These findings suggest that the Anjasmoro soybean variety has a low drought tolerance.
