Adaptation of Elements of Sudan Grass Cultivation Technology to the Conditions of Dry-Steppe Zone

Abstract

Sudan grass (Sorghum sudanense (Piper.) Stapf) for the dry-steppe zone of West Kazakhstan is the most productive and drought-resistant, as well as promising culture. Therefore, in order to ensure the smooth supply of feed to livestock, it is important to carry out studies on the adaptation of elements of Sudan grass cultivation technology to the regional conditions. The research examined different sowing times at 10-day intervals, and for the harvesting of green fodder, haylage and hay, the harvesting times were examined in different phases of development, as well as grazing mode of use of Sudan grass. The results of scientific research showed that for the 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, with the 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.

Effects of Different Cutting Stages and Additives on the Fermentation Quality and Microbial Community of Sudangrass (Sorghum sudanense Stapf.) Silages

“…is an important annual grass and is a C4 plant, with excellent characteristics such as a high yield, barren and drought tolerance, and strong resistance to diseases and insects [1,2]. It can also be used as forage grass for livestock due to its high nutritional value, good palatability and strong regeneration capability, which is better than most annual grasses, and it can be mowed three to four times a year [3][4][5]. Therefore, sudangrass is used as animal feed, for example, as silage, in many countries, including China [6,7].…”

Initiation of safflower sowings in the organic farming system of Western Kazakhstan

“…The study of phytoameliorative role of safflower in the conditions of dark chestnut soils of Western Kazakhstan. The modern agriculture of Kazakhstan is currently in a situation where it is necessary to solve the problems of soil fertility restoration, associated with a severe reduction in the fields occupied by forage grasses, green manure crops, decrease in the use of organic fertilizers, non-observance of crop rotation systems (Nasiyev and Yeleshev, 2014;Nasiyev et al, 2020a). Therefore, to maintain or restore agricultural soils in terms of fertility factors, it is necessary to develop agronomic practices using new and traditional green manure crops.…”

“…More than 15 million hectares of land removed from sowing become a reservoir of disease and pest pathogens. These problems can be largely solved with the effective use of bioorganic fertilizers (Nasiyev et al, 2015(Nasiyev et al, , 2020a(Nasiyev et al, , 2021.…”
