The aim of the study is to analyze soil cultivation technologies and development trends of tillage machines in the Republic of Uzbekistan. The prospects of using dump and non-dump soil tillage are shown. Existing basic processing technologies are presented. The advantages and disadvantages of traditional technologies and plows for primary tillage are analyzed. The advantages of the new technology of smooth plowing and frontal plows for its implementation are given. The expediency of developing and implementing combined machines that carry out various technological processes in one pass of the unit and special-purpose plows for working in gardens and on slopes based on frontal plows is substantiated. The perspectives of the application of technologies and tools for anti-erosion and land reclamation cultivation, phytomeliorative works based on minimal narrow-band soil cultivation and sowing are shown. Directions of developments in the field of mechanization of tillage in the future are given.

Current study aimed to explore the nexus between energy and economic growth in post-communist nations during 1995-2014. As an empirical model, the growth model is employed including economic complexity indicator as a measure of capabilities for exporting sophisticated products. We employ Pedroni's (1999) panel cointegration tests and Panel Dynamic OLS estimation to assess the long-term link between the variables. At 1% significance level, we confirm cointegration between energy consumption and economic growth. Panel Dynamic OLS results revealed that economic growth positively influences energy consumption in Post-Communist states. The Dumitrescu and Hurlin (2012) panel Granger causality test results discovered unidirectional causality running from economic growth to energy consumption. Economic growth causes energy consumption in post-communistic countries, confirming the conservation hypothesis.

The aim of this study was to develop an improved technology for ridge-stepped ploughing of slopes and plow, which protects the soil from water erosion, improves the accumulation and preservation of soil moisture. The paper proposes an effective method for ridge-stepped ploughing of slopes, including the alternation of layer’s incomplete rotation with its full rotation within its furrow by 1800 in combination with the band subsoil loosening. A technological model of a ridge-stepped ploughing with simultaneous subarable strip loosening was developed. The design of the developed plow for ridge-stepped ploughing is highlighted. During the study the followings were theoretically and experimentally established: with a longitudinal distance between the hulls of 50 cm, the required qualitative incomplete turnover of the layers with the lowest energy costs is provided with the following plow’s parameters of the odd hulls: plow length is 75 cm, plow width is 25 cm, stabilizing plate height is 15 cm, and the minimum distance from the ploughshare toe to the stabilizing plate is 25 cm.

This article depicts on discussions about land use and land cover change distribution in Khorezm province, Uzbekistan between 1987 and 2019. For the study Landsat 5 TM and Landsat 8 OLI respectively used to detect land use changes in the study area. Khorezm region affected by Aral Sea shrinkage having received salt wind from northeast of the region. Moreover, population increased within study period, making population density intense. Research is carried out to detect reflection of ecology and density in land use. RS techniques maximum likelihood employed to classify land use to generate land cover distribution map. In total seven class selected such as agricultural land, built up, bare land, lowland, saline land, sand and waterbody. The research of Khorezm region for 32 years has been thoroughly studied and found out that agricultural land, built up and saline land increased tremendously while lowland and bare soil are decreased accordingly. The result map can be used for decision makers and government bodies for future long term urban and regional planning.
