THE GROWTH, DEVELOPMENT AND YIELD FORMATION OF SWEET CLOVER, DEPENDING ON THE SYSTEM OF SOIL IN THE REGION OF KYZYLORDA OBLAST

This article describes the results of the study of the growth, development and formation of yield of sweet clover depending on the type of treatment on saline soils of the Kyzylorda region. It is known that sweet clover is an excellent phytomeliorant. It should also be noted the prospects and value of sweet clover, which consist in its exceptional ability to produce high yields of fodder in saline areas, its ability to cultivate the soil, making it suitable for sowing other crops, in this case rice. It is established that the methods of the main tillage have an impact on the accumulation and preservation of soil moisture. In the experiments, various types of saline soil treatment were used, such as dump treatment, dump-free processing and chiseling. Depending on different methods of treatment, soil moisture ranged from 18.5 % to 23.4 %. The optimal growth is observed in the case of non-dump tillage with subsequent harrowing, in which there is a better water regime of the soil sowing of sweet clover from germination to the beginning of branching and ensures the safety of plants in 1.4-1.8 times more, and the yield of green mass of sweet clover increases in two years by 35.7-55.0 %
