Abstract

The article presents the results of research on the development of a technology for growing cotton with targeted and uniform moistening of the root systems of plants, which jointly contributed to the creation of optimal conditions for machine harvesting of raw cotton by ensuring early ripening (for 2–3 weeks) and a high yield. Among the measures reducing the labor intensity, further improvement of technology and means of mechanizing cotton sowing is important. The cotton cultivation on the ridge by the soil cultivation theory creates possibilities for adding the arable layer during a high growing season of cotton, which allows for obtaining friendly shoots, developing plants and obtaining a large amount of cotton-raw that ripe early. There is no sign of moisture accumulation in the soils, resulting in soil dusting, structure destroying and soil crusting, forcing creating a “drip irrigation system” providing plants with water and fertilizer if necessary. The use of “drip irrigation” guarantees higher yields and saves labor, water and energy resources. For the use of drip irrigation systems on farms with flexible perforated irrigation tapes laid in the upper part of the bed along its entire length, it is carried out simultaneously with the sowing of cottonseeds, which makes it possible to exclude manual layout of irrigation hoses, i.e., a time-consuming manual operation to start urgent irrigation work.
