Studying the effect of preplanting tillage on the germination and forage productivity of Kochia prostrate in the northern desert of Kazakhstan

The article is devoted to the description of the advantages and features of the resource-saving method of land cultivation using the Strip-Till technology. Also the results of the search for the possibility of using it in the conditions of the Republic of Uzbekistan when growing of re-crops in exiting furrows and in row spacing ridges are presented. As a result of experimental studies, the hardness and moisture content of the soil were determined, and data on the quality of soil cultivation by the developed working bodies were obtained. The layout schemes of the working bodies in the design of the unit for the considered technology are presented. The results of studies on the choice of types and design of working bodies for strip tillage are substantiated. It was found that the equipment of the aggregate with sections consisting of 3 flat cutting discs and a lancet chisel best ensures the required quality of soil loosening and equable depth of its processing, as well as the width of the cultivated strip and evenness of the treated area, protects the organs from clogging with soil and grower residues. For normal operation of the planter working bodies, the cultivated strip width of the soil must correspond to the planter coulters width.

“…The use of strip processing ensures the formation of a more developed root system of crops. The increase in the total volume of the roots is 20-40%, compared with traditional technology [1,2]. This improves the access of plants to soil moisture and nutrients.…”

In view of the problem of the specific condition of the fields after harvesting winter crops, special tillage is required to use them for re-sowing. For this purpose, strip tilling was chosen as the most suitable technology. Data on the experimental search for the using it for the rear of repeated crops in permanent drills and in aisles ridges are presented. Based on the principle of vertical and horizontal cutting with simultaneous loosening of the soil, working organs were developed and experimentally tested. The data on the quality of tillage by the working bodies of the recommended device obtained in experimental studies are given. A schematic diagram of the designed combined aggregate with a device for strip tillage before sowing repeated crops is shown. A diagram of the arrangement of the device organs is given. The methods and materials of experimental tests, which were run in two stages, are also indicated. Graphs of changes in the degree of soil grinding and proposed organs traction resistance are described depending on the distance between the ripping disks and the lancet share. The experimental tests results of justification the optimal values of the parameters of the working organs for strip tillage of developed combined aggregate are presented. Based on the results of the research, the results were obtained on the justification of the parameters of the working organs for strip tillage of combined aggregate. The developed aggregate can meet the requirements of no-till sowing of repeated crops. This study can provide recommendations for the design and improvement of implements for reduced tillage in the conditions of Central Asia.

A system of agriculture is being developed to accumulate and preserve moisture in soil strips (5-10 cm wide, 5 cm deep, repeated every 50-55 cm in virgin soil untouched by vegetation), treated by surface raking of the loose seedbed layer to form a solid compacted bed, where an ideal condition for seed germination is created. With a favorable combination of weather and climatic conditions, this variant provides an optimal fullness of seedlings and a fairly high fruit-bearing weight of 3.9 t/ha on average for four years, including 4,8 tons in 2019. However, in extraordinary 2019-2020 crop year with extremely low precipitation (2,7 times lower than average annual norms), with the warm winter and spring (100 more than the average annual norm), incredibly intense droughts and dust storms (average of 18-19 days a month vs 4-5 mean annual norm) wind erosion dominated and dictated terms everywhere: furrows, sown with seeds of Summer Cypress were completely covered with drifts of dust with a thickness of 2-3 cm, under which the seedlings could not break through to the surface of the soil and died. In the cultivar keeping nursery, where seeds were sown directly without tillage and 15 PCs/m2 of seedlings were obtained only in the dust-inspired areas that make up one third of the area (400 m2).
