Formation of agricultural landscapes of the sudan grass in the dry zone

Abstract

Field experiments on the study of elements of Sudan grass (Sorghum sudanense (Piper.) Stapf) cultivation technology were carried out in the spring and summer periods in the dry-steppe zone of Western Kazakhstan. The research examined different sowing times at 10-day intervals, and for the harvesting of green fodder, haylage and hay, the harvesting times were examinedin different phases of development, as well as grazing mode of use of Sudan grass. The area of divisions is 50 m 2, repetition - threefold, location of divisions is random.The results of scientific research showed that forthe conditions of the region it is important to select both optimal sowing and harvesting times. In the years of research, the yield of dry mass of Sudan grass at different sowing times was 21.05-23.37 c/ha, withthe highest productivity determined at 1 early sowing time. When studying the time of harvesting, high yield of dry mass of Sudan grass was ensured during harvesting of plant formations in the blooming period 19.06-23.69 c/ha. Under grazing conditions in the study area, Sudan grass produced 16.99 c/ha of dry mass in a total of 4 browsing
