SOME ECOLOGICAL AND BIOLOGICAL BASES OF TECHNOLOGY OF SOY GROWING IN THE CONDITIONS OF THE STEPPE ZONE OF THE KBR
The influence of the timing and methods of sowing two soybean varieties (Vilana, Select 301) on the grain yield in the steppe zone of the KBR was studied. The technical and economic efficiency of various care methods has been determined, preserving from losses up to 3.5-8.5 c / ha of seeds of the crop with a high degree of suppression of the weed-field community - up to: 60.3-86.6% in quantity and 81.2 -91.0% by weight for harvesting grain products. The advantage of using herbicides has been proven: Panthers with a reduced application rate of 1.0 l / ha in the phase of 3-5 leaves of the crop against the background of applying the soil preparation Gezagard in 2.5 l / ha before sowing for cultivation compared to high doses (1, 5 and 3.5 l / ha, respectively) of their use.
