Our collection of dwarf lines, obtained in the result of cyclical diallel crossings of genotrophs, induced by pyridine carbonic acids, zoned common wheat cultivars and short stem common wheat samples from the World Wide Collection of the Russian Institute of Plant Industry, was applied for creation of new common wheat lines having valuable morphological traits. It was observed that open blooming dwarfs were good for cross-pollination, and without insulation they demonstrated a great issue of natural hybrids. It was marked that cross-pollination promoted appearance of great number of hybrid plants with high productive tillering capacity. After individual selection among those hybrid plants and their propagation we got fertile constant lines of common winter wheat having 17-20 productive stems per one plant and a productive ear. These lines are firm and resistant to lodging. At the present time these constant lines are cultivated in conditions of resource-saving ridge technology.展开更多
Conservation agriculture （CA） is especially relevant for Uzbekistan＇s agriculture, particularly in non-irrigated lands where soil fertility has been steadily declining and the risk of crop failure has been growing....Conservation agriculture （CA） is especially relevant for Uzbekistan＇s agriculture, particularly in non-irrigated lands where soil fertility has been steadily declining and the risk of crop failure has been growing. CA has three main characterizations given in scientific literature, which are the minimal soil disturbance, crop rotation and surface crop residue retention. Nowadays, the majority of farmers are not widely using CA in their agricultural practices in Uzbekistan. Maybe, this is due to different perception of the economic efficiency of CA. The objective of the research was to calculate economic efficiency of CA in non-irrigated lands and to show whether it is effective or not in agricultural production. To achieve this objective, literature review including a variety of secondary data is employed. Overall, the costs of labor and fuel consumption per ha at CA technology are less in comparison with conventional technology. Using CA practices gives a chance to increase labour productivity, to use resource effectively and to improve soil quality and crop diversification.展开更多
