The influence of sowing rates of winter wheat varieties planted in Bukhara region on seed viability and actual seedling thickness

One of the main criteria of economic stability is the effective use of available resources and opportunities by every agricultural enterprise operating in the conditions of the market economy. One of the main requirements of today's farming is to collect the planned amount of seedlings and grow a high yield with the economical use of seed material, crop area, especially irrigation water. Based on this goal, a field experiment was conducted under the soil-climatic conditions of Bukhara province on the topic “Effect of seedling thickness of autumn wheat cultivars on the processes of water exchange in plants”. In the experiment, when the seeding rate was increased from 4.5 million/ha to 6.5 million/ha in “Grom”, “Alekseevich”, and “Kelajak” varieties of winter wheat, the field fertility of seeds decreased to 1.5-3.2%. The seedling thickness of the plants was studied in early spring and at the end of the season, and a certain decrease in the number of plants was observed during the winter season and the spring growth period.
