Abstract

This study aims to determine the response of growth and production of soybean (Glycine max L) on the time of offering irrigation water in maintaining soil moisture. Research in the form of an experiment using a randomized block design (RAK) consisted of four times of air giving, namely W1 = every 15 days of age, W2 = at full flowering, W3 = at the age of 15 days and at full flowering, W4 = every 10 days. The amount of air given is the same for each treatment, only the time to offer it is different, where the water requirement for soybean plants is obtained from previous research data where it was found that the water requirement for soybean crops was 6.1 liters per plant during its life cycle, the number of plants in one bed was 75 so that The total air needed in one bed until production is 457.5 liters = 458 liters. W1 = every 15 days of age (5 times to offer) = 458/5 = 91.6 = 92 liters, W2 = at full flowering (1 time to offer) = 458 liters, W3 = at the age of 15 days and when it is full (2 times giving) = 458/2 = 229 liters and W4 = every 10 days (8 times of giving) 458/8 = 57.25 = 57 liters. The results of the investigation showed that offering every 10 days showed the highest water content (soil moisture) compared to other treatments, but the highest moisture content was not in line with the increase in the production component. The treatment of giving water every 15 days and offering water while giving full warning of the best effect on almost all production components, namely the number of seeds planted (161.99), weight 100 seeds (27.5 grams), number of pods (80.67), the weight of seeds per plant (23.83 grams), and production per hectare (3.2 tons/hectare). This shows that the time to offer water at the age of 15 days and when it is in full bloom with the amount of giving 229 liters of water each time (twice) is able to meet the optimal water needs of the growth phase and development even to the production of soybean plants.
