Climatic conditions of Central Asia are characterized by a large amount of sunlight and heat, suddenly changes in annual and daily air temperature, low annual atmospheric precipitation, dry relative air humidity. The rainfed lands of Uzbekistan receive less rainfall than other dryland regions of the Central Asian republic, and therefore more droughts are observed. Scientific researches are being carried out at the Scientific Research Institute of Rainfed Agriculture on the creation of new varieties of grain, oilseed and forage crops for cultivation in the rainfed conditions of Uzbekistan. The yield and productivity of agricultural crops in rainfed lands are strongly influenced by weather conditions during the crop's vegetation. The article presents the results of research on the effects of intense heat and drought during the growing season on the productivity indicators and productivity of varieties and samples of agricultural crops such as wheat, barley, safflower, flax and alfalfa under conditions of global climate change.
