Abstract

Soybean production in Indonesia has decreased year by year. This is caused by high rainfall potentially causing water-saturated land. This is due to heavy rain which can cause the water to become saturated. Implementation of drainage and groundwater depth control is expected to increase soybean productivity. The purpose of this study is to determine the best groundwater depth for growth, production and physiological quality of soybeans produced. The study was conducted at the Experimental farm of the Faculty of Agriculture, the University of Riau from February to May 2019. The depth of the groundwater used was 5 cm, 10 cm, 15 cm, 20 cm, and control treatment. The parameters observed were plant height and number of nodes, flowering age, age of harvest, number of seeds per plant, dry weight of seeds per plant, the weight of 100 seeds per plant, the suitable percentage for seed, standard germination test, and index value test. Data were analyzed by analysis of variance then continued with Duncan's New Multiple Range Test at the 5% level. The results showed that a depth of 5 cm, which produces poor aeration, leads to unoptimal absorption of nutrients, thus plant height and number of nodes, number of seeds per plant, dry seed weight  per plant, 100 seed weight  per and the suitable percentage for seed decreased. In the treatment, a water level of 20 cm from the soil gave the best results in terms of seed growth, production and physiological quality  due to good ventilation, sufficient water availability and optimal absorption of nutrients.
地下水对大豆生长、生产和生理质量的影响
印尼的大豆产量逐年下降。这是由于高降雨量可能导致土地饱和造成的。这是由于大雨会导致水变得饱和。实施排水和地下水深度控制有望提高大豆产量。本研究的目的是确定大豆生长、生产和生理品质的最佳地下水深度。该研究于2019年2月至5月在廖内大学农学院的实验农场进行。地下水使用深度分别为5 cm、10 cm、15 cm、20 cm和对照处理。观察的参数为株高、节数、开花年龄、收获年龄、单株种子数、单株种子干重、单株100粒重、适种率、标准发芽试验、指数值试验。通过方差分析对数据进行分析,然后在5%的水平上继续进行邓肯新多元极差检验。结果表明:5 cm深度通气不良,导致养分吸收不理想,导致株高、节数、单株种子数、单株干粒重、单株百粒重和种子适宜率下降;在距离土壤20厘米的处理中,由于通风良好、水分充足和养分吸收最佳,在种子生长、产量和生理品质方面取得了最佳效果。
