Effectiveness of Water Management towards Soil Moisture Preservation on Soybeans

Abstract

In this study, factorial randomized experiments were conducted in a controlled greenhouse environment to investigate an efficient and effective component of water management technology in increasing soybean yield. The soybeans were planted in polybags with 6 kg of Alfisol soil media and fertilizer. The bags were perforated with 16 holes at approximately 1 to 2 cm from the base and put into a water container. The container was immersed in water levels of 5 cm and 10 cm. The application of these immersions was carried out in four stages: 0 to 15 days after planting (DAP), 15 to 30 DAP, 30 to 45 DAP, and continued until harvest. Observations of growth were carried out on the greenness of leaves, plant height, leaf area, root length, and dry weight of plants, and soil water content was checked every two weeks. The yield measured after harvest consisted of the number of pods, the number of seeds/plants, weight of 100 seeds, and weight of seeds per plants. The water level had a significant effect on plant height, dry weight, leaf greenness, number of pods, and number of seeds/plants. The immersion stage has significant effects on plant height, harvest age, dry weight, leaf greenness, number of pods, and number of seeds/plants. Continuous immersion in a water level of 5 cm has shown the best yield on number of pods (20.81) and number of seeds per plant (162.94). This treatment increased seed yield (seed weight) approximately by 19.23% compared to the field capacity.

Response to the Growth and Production of Soybeans (Glycine max L) to the Time of Giving Irrigated Water to Maintaining Soil Moisture

“…The longest root length was shown by the treatment of water when in full flowering, where this treatment showed that the soil was deprived of water due to water supply at once and only once so that the roots would extend themselves (root interception) to find further space to get water, this is in line with the study [18] which found that soybean plants that were stressed by water tended to extend themselves compared to plants that received normal irrigation.…”

APPLICATION OF WATER PROVISION ON THE GROWTH AND PRODUCTION OF SOYBEAN (Glycine max L)

“…This is because almost every phase of plant growth and development is available enough water so that production is higher. This is in line with research by Aminah et al (2020) who found that continuous immersion with a water level of 5 cm increased soybean seed yield (seed weight) by 19.23% compared to field capacity. because this was supported by an increase in harvest components such as the number of pods and the number of seeds planted by 31.1% and 37.59% compared to field capacity, respectively.…”

Effectiveness of Irrigation Methods and Time of Providing Water in Maintaining Soil Classification for Increasing Soybean Production

“…Of the two photosynthetic pigments classes carotenoids show multifarious roles in tolerance to water deficit including light harvesting and protection from oxidative damage caused by soil water deficit (Kapoor et al, 2020). Aminah et al (2020) reported that keep a water surface at five centimeters increases the weight of soybean seed by 19.23%. The increase of harvest components in the number of pods and the number of seeds/crop by 31.1 % and 37.59% compared to field capacity.…”
