LEAF AREA OF SOYBEAN DEPENDING ON SOIL AND CLIMATIC CONDITIONS AND CULTIVATION TECHNOLOGY
Abstract
The results of research on studying the dynamics of leaf area formation of soybean early-ripening determinant variety Pripyat under conditions of two varieties of sod-podzolic soils (medium loamy and sandy loam slightly gleyic) cultivated against the background of three technologies of different intensity (intensive, normal, extensive) are presented. It was found that the maximum leaf area of soybean was formed in 2022-2023 in the phase of the beginning of seed filling on medium loamy soil and equaled to 3.0 m2 /m2. On sandy loam soil only in 2021 the leaf area of soybean in the flowering phase almost corresponded to that indicator on medium loamy soil (2.2-2.3 m2/m2), and in 2022-2023 was lower by 1.4-2.0 times. The greatest differences in leaf area index between intensive and extensive technologies were observed on sandy loam soil. Leaf area is an indicator largely dependent on soil and climatic conditions and cultivation technology and it is suggested to be used for stress assessment under different growing conditions.
