Item Water use efficiency in biology, agriculture and sustainable development(CEP USM, 2024-10-07) Harciuc, Oleg; Malii, AlionaIn the Republic of Moldova 2017-2023 water use efficiency in rainfed soybean fields was in the range of 0,3-0,8 g grain/kg water. Under field conditions, for the Ladutsa soybean variety, a WUE of 0,75 g of grain/kg of water was obtained with seasonal precipitation of 94 mm, which is several times less than 317 mm, considered optimal for achieving the average agricultural WUE of 0,57.Item WATER USE BY SOYBEAN VARIETIES OF DIFFERENT MATURITY GROUPS(CEP USM, 2023) Malii, Aliona; Harciuc, OlegThe seasonal change in soil moisture reserves in dependence on the genetic form of soybeans was studied. It has been established that the deep layers of the soil (40-150 cm) more consistently reflect the influence of the plant component than the surface ones. In 2021, water reserves decreased in the 0-150 cm layer: for the Pentata variety - by 103 mm, and for the Onika variety- by 53 mm. Thus, Onika variety (MG I) retained 50 mm more water in the field for the next season compared to variety Pentata (MG III).Item CRITICAL SOIL MOISTURE IN RAINFED SOYBEAN FIELD(CEP USM, 2023) Harciuc, Oleg; Malii, AlionaThe content of soil moisture in different soil horizons of soybean fields in the 0-150 cm layer was studied in years with different meteorological conditions. The current forecast of the degree of aridity of the growing season is carried out according to soil moisture data in the soil layer 0-150 cm. In the sawing the critical level of soil moisture in rainfed soybean fields was 300 mm. In the pod filling stage the critical level of soil moisture in rainfed soybean fields was 200 mm.
