Respons Pertumbuhan dan Produksi Varietas Kedelai (Glycine Max (L) pada Penggenangan dan Pemberian Putrescine

Abstract

This research aims to determine whether the use of putrescine on soybean plants against waterlogging stress can increase soybean production. This research was carried out from May to August 2023 using Split Split Plot Design. The factor consists of 3 treatments, namely: (V) Varieties consisting of the Agromulyo (V1), Deja 2 (V2) and Dering 2 (V3). (T) Putrescine consists of control (T0) and 150ppm (T1) and (G) Puddling stress consists of control (G0) and 50% puddling (G1). Data were analyzed using Analysis of Variance (ANOVA) for each parameter measured and further tested for real treatments using the Duncan Multiple Range Test (DMRT) at the 5% level. The parameters observed were plant height, number of leaves, stem diameter, flowering time, number of pods per plant, number of filled pods, number of empty pods, and seed weight. The results showed that the combination of the three treatments, namely, variety, putrescine concentration and waterlogging, had a significant effect on soybean plant height at 3 WAP, variety had a significant effect on plant height at 4 and 5 WAP, number of leaves at 1 and 2 WAP, stem diameter at 1 WAP. and flowering age, waterlogging stress had a significant effect on plant height at 5 WAP, number of leaves at 6 WAP, flowering age, number of pods per plant, number of filled pods, and seed weight per plant, putrescine had a significant effect on number of pods per plant, number of pods. contains and weight of soybean seeds.
