  • 摘要:Agricultural land plays an important role in ensuring food security and employment in rural areas. For many years, the planned economy has forced Uzbekistan to grow water-intensive crops, which has led to declining land productivity and increased crop yields. In a market economy, new innovative technologies are in high demand not only in agriculture but also in other sectors.In order to solve the above-mentioned problems, our research has found it necessary to set goals and objectives.The purpose of the study was to substantiate the parameters of frontal plowing slope, which provides high-quality execution of the technological process in accordance with the agro-technical requirements with minimum energy consumption without furrow plowing, agrotechnical and energy performance of variable frontal forks.The following results were achieved by performing the tasks identified in the study: a – humidity V=16–17?% and load conditions with elastic rods of 3?mm, 4?mm, 5?mm; b – humidity V=13–14?% and the diameter of elastic rods is 3?mm, 4?mm, 5?mm; c – humidity V=9–10?% and the diameter of the elastic rods is 3?mm, 4?mm, 5?mm.The experiments were performed on lumps with different humidity conditions: 9–10?%, 13–14?% and 16–17?%. The speed of the installation was 1.0?m/s.The recommended technology was to destroy soil fragments with a moisture content of 16–17?% at a vertical load of 400?N with 3, 4 and 5?mm elastic rods at 86.6, 81.5, 75.1?%, respectively, and the vertical load equal to 1,000?N – 94.4, 89.2, 81.2?%, respectively.
