Abstract
For the rational use of the lands of the south-east of Kazakhstan, the influence of various methods of tillage on its water-physical properties has been studied. The reserves of productive moisture in the soil were on average in the range of 103.3-134.1 mm for all studied crops. Due to a decrease in precipitation, due to evaporation and transpiration, by the harvest period, productive moisture reserves decreased in all variants: 18.9-27.5 mm during plowing; 22.9 - 26.9 mm during minimal treatment; 24.3–31.6 mm during zero treatment, while the amount of moisture reserves was higher with zero and minimal tillage. The study of the dynamics of nutrition elements in experiments showed that during the germination period of the studied crops, a low accumulation of nitrate nitrogen was observed in the soil – an average of 25-29 mg/kg. At the end of the growing season of the studied crops, its content in the soil decreased to 17-22 mg/kg, minimum treatment to 13-27 mg/kg, zero treatment to 15-26 mg/kg. The content of mobile phosphorus in the soil in the spring ranged from medium to high 26-44 mg/kg. By the end of the growing season of the studied crops, its content in the soil decreased and remained in the specified supply group. The content of exchangeable potassium ranged from 307-448 mg/kg, which indicated medium and high levels of content. According to the research results, it was found that among the studied crops, the grain yield of the spring barley variety Symbat was in the range of 10.8-32.9 quintals per hectare, that is, for all the years of research, the highest yield was observed in the variant of minimal processing. According to the research results, the significant influence of the meteorological conditions of the year has been confirmed.
