Abstract

In recent years, the increase in grain yield under irrigated conditions has led to a decrease in technological quality of grain. The main reason for this is the lack of nitrogen during the grain formation in wheat on gray soils with low humus content. Under irrigated conditions, one of the most urgent tasks is to increase the grain yield of winter wheat and improve technological quality. According to the results of scientific research, today winter wheat absorbs 50-55% of nitrogen fertilizers, 20-22% of phosphorus fertilizers and 55-60% of potassium fertilizers. Some of the nitrogen fertilizers not assimilated by the plant are released into the air in the ammonia state, while some are washed into the groundwater in the nitrite and nitrate state. This situation has a negative impact on the environment. This condition is prevented when the leaf orchids are fed, as well as the rate of absorption of phosphorus by the plant increases sharply.

Highlights

Full satisfaction of the population's demand for grain and grain products is one of the most urgent tasks in today's era of gradual transition to a market economy and the formation of new forms of ownership [1, 2].According to the FAO, over the past 18 years, world grain production has reached 1.16 billion tons and increased by 2.3 billion tons
The total leaf cover of winter wheat was determined by the method of Nichiparovich, biological productivity Shatilov and Kayumov, the amount of protein in the grain was determined by the Keldal method, the amount of gluten was determined by the washing method [7,8,9,10,11]
Leaf feeding is especially important in cereals, especially in the cultivation of winter wheat, especially in irrigated conditions; the application of this method in the nitrogen feeding of winter wheat ensures high efficiency

Summary

Introduction

Full satisfaction of the population's demand for grain and grain products is one of the most urgent tasks in today's era of gradual transition to a market economy and the formation of new forms of ownership [1, 2]. According to the FAO, over the past 18 years, world grain production has reached 1.16 billion tons and increased by 2.3 billion tons. The world wheat yield is not high (27.1 quintal (q)/ha), which is not enough to meet the grain needs of the population. The demand for wheat in the world is growing by 1.6-1.8% per year [3, 4]. Special programs have been developed to provide the population of the country with domestically grown grain, as a result of which the yield of winter wheat has increased 2.53.0 times [5]. The yield of winter wheat on irrigated lands is 55-60 q/ha [6]
