AMOUNTS OF AMYLASE, STARCH AND PROTEIN IN THE GRAIN OF RICE (Oryza sativa) VARIETIES GROWN IN DIFFERENT WATER THICKNESSES

In this article, taking into account the biological characteristics of regionalized early-ripening "Guljahan", mid-ripening "Ilgor", Iskandar" late-ripening "Mustaqiliklik", "Lazurniy", "UzROS-7/13" varieties of rice, grown in different water thicknesses, in the conditions of grassland-swamp soils of  Tashkent region. amylase, starch and protein contents of rice grain were determined. Rice varieties 5; 10; When grown in water thicknesses of 15 and 20 cm, the amylase content of "Lazurnyy" variety is 21.4%, starch content is 69.9%, and protein content is 11.2%, which is higher than other varieties.
