WATER-BALANCE NUTRITION OF WINTER WHEAT VARIETIES PLANTED AFTER REPEATED SOYBEAN CROPS
ABSTRACT
The article gives the norm of the nutrient water balance of the varieties "Asr" and "Durdona" and the order of watering the autumn grain planted after re-shading the autumn grain. The analysis materials based on the results of studies conducted on the lands of the training and experimental farm in order to determine the rate of fertilizing and watering procedures for very early-maturing varieties of autumn willow are presented. The data obtained were analyzed and recommendations were given for extremely early-maturing varieties of autumn willow.

В статье дана норма питательного водного баланса сортов "Аср" и "Дурдона" и порядок полива осеннего зерно, высаженного после повторного затенения осеннего зерно. Приведены анализные материалы по результатам исследований, проведенных на землях учебно-опытного хозяйства с целью определения нормы подкормки и поливных процедур очень скороспелых сортов осенней ивы. Полученные данные были проанализированы и даны рекомендации для экстремально раннеспелых сортов осенней ивы.

Today, in more than 132 countries of the world, it has raised 220,4 million. hectare, of which 12,3% consists of irrigated land, the average grain yield is 31,1 centner per hectare, the main part of food products are grown in these areas.
It should be noted that in the following years, a number of inconveniences in the cultivation of abundant and high-quality grain crops have been brought about by a sharp change in climate, especially in the autumn cultivation, the soil-climatic conditions of the region, the type of agrotechnical measures are important used, etc.
The problems of salinity prevention in the arid regions of a number of countries of the world, including the USA, Australia, Russia, China, India, Pakistan, Bangladesh, North Africa, Central Asia, South Kazakhstan, the Caucasus, are being solved by the use of agrotechnical, agrochemical and meliorative measures. Therefore, the norm of irrigation and seasonal irrigation, watering periods are carried out depending on the natural and climatic conditions, depending on the water demand of each crop.
Application of scientifically based irrigation procedures for crops in the conditions of water shortage in World Agriculture. The shortage of Water Resources today significantly indicates the negative impact on crop yields and its quality. In this respect, it is urgent to carry out research on modern scientific-based irrigation procedures that save water and resources, improve the land reclamation by further improving water-saving theologies.
Due to different soil climatic conditions of the Republic, it is possible to achieve food safety by developing irrigation procedures and norms of autumn after repeated shade, obtaining high and quality grain yield.
First, we must say that more than 90 percent of the agricultural products grown in our country correspond to the contribution of irrigated lands. It remains to be noted that in the following years, water scarcity in our region is increasing.
The water balance of the field is subjected to irrigation procedures-it depends on the growth rate and seasonality of irrigation. Irrigation rates at the entrance to the water balance, soil moisture, zinc consumption, precipitation, water balance composition, evaporation from the soil surface, evaporation from the soil surface, and moisture leakage from the calculated soil layer.
As it turned out, the order of soil moisture affects the entire amount of Water spent from the wheat field, the water balance composition tens. In addition, the general water consumption is a variety, the yield of which depends on the Metrological conditions of the years of experience.
At the end of the follow-up-growth period, it was observed that the most moisture loss in the irrigated variant was at 65-65-60 percent compared to the limited field wet capacity in the soil moisture content. The main part of the total moisture spent on the field wheat falls on the water used for irrigation.
But the comparative consumption of water used in irrigation in general water consumption is tied to the water buying Order of the soil. In the course of the study, various water nutrient procedures seriously affect the growth, development, accumulation of dressing, accumulation of dry matter in wheat. These are also affected by the so-called unspoken temperament. To obtain one centner dressing was spent on water in 5-6 variants 33.2-63,5 m3/ts, these indicators are in 1-2-3-4 variants 80,7-59,5-74,3-43,5 it consists of m3 / c.

Analyzing and concluding the results of the above many years of scientific research, the order of irrigation of autumn in the conditions of the Andijan region's Meadow soils has not been studied systematically, in determining the elements of irrigation techniques, agrotechnical measures and physical properties of the soil have a great importance.
Observations show that excessive moistening of the head part of the rut in irrigation, a lack of moisture in the skirt part leads to a sharpening of the degradation state in the soil. Therefore, depending on the mechanical composition of the soil, when the irrigation method was chosen, it was divided according to the purpose of making a correction to this theory.
These confirm the correct choice and relevance of the subject of the dissertation. In the course of the experiment, phenological observations revealed the periods of germination, pickling, germination, ripening (milk,wax,whole) of new and promising varieties of autumn. The resistance of plants to winter and Frost was determined by counting the number of healthy plants before wintering and in the spring.
At the end of the growing period, in field conditions, the height of autumn wheat varieties, the number of fertile soils were determined. In laboratory conditions, such indicators as Spike length (sm), number of grains in spike (quantity), grain weight in single spike (gr), grain weight in 1000 (gr), grain volume, protein content in grain, gluten content, IDK were determined.
