RESISTANCE AND PRODUCTIVITY INDICATORS OF CEREAL CROPS TO EXTERNAL FACTORS IN MEDIUM SALINITY SOIL - CLIMATE CONDITIONS

This article is based on the data obtained in the field experiments conducted in order to determine the resistance to abiotic and biotic factors and productivity elements of barley and triticale varieties planted in the demonstration field of Syrdarya region. In the experiment carried out in field conditions, when the plants were harvested and the biological yield was determined, the triticale "Boyovut" variety - 88.3 t/ha, the "Tuyatish" variety - 83.1 t/ha, the barley "Mashuldar" variety - 67.6 ts/ha, in "Sayhun" variety - 69.0 ts/ha and in "Syrdarya" variety - 65.8 ts/ha. It was observed that the indicators of resistance to external factors were higher in barley varieties, and based on the biological capabilities of the plant, productivity elements were higher in triticale varieties compared to barley varieties
