INTRODUCTION

In the world, the role of the maize plant is high in 

satisfying the demand of the population for food 

products, industry for raw materials, and livestock for 

nutritious food. Special attention is paid to the 

development of agrotechnologies of plant cultivation 

taking into account different soil and climatic 

conditions. Maize ranks the third place in the world 

after wheat and rice by cultivated area, and the first 

place in the group of fodder crops. Today, the area 

planted with maize plants is 22.5 million in the USA, 

20.6 million in China, and 11.8 million in Brazil. hectares, 

and according to FAO data, in the structure of crops, 

the area of maize is 23% more than wheat in the USA, 

63% in Australia, 70% in Germany, 43% in France, and 

3.5% in Russia, the average yield consists of 7-10 tons 

per hectare [1, 2]. 

Maize ears (spikelet) contain more than 20 valuable 

microelements. Maize grain is rich in folic acid and 

magnesium, and regular consumption provides the 

human body with the required amount [3]. 

In the experiment of foliar feeding in the cultivation of 

maize plants, when treated with 1.0% preparation of 

H2O2, it was found that the green mass and yield of 

maize increased compared to the control options [4].

Maintaining the quality of the crop using all available 

methods of pest population management is 

considered one of the urgent problems of the 

integrated control of maize pests [5]. 

Among cereal crops in the world, maize is widely 

grown, the total area is 162 million hectares, the 

harvest is about 850 million tons, the average yield is 

5.2 tons/ha, the countries that grow the most are 

America, China [6]. 

MATERIALS AND METHODS 

In the conducted research, agrochemical analysis, 

biometric measurements, phenological observations, 

irrigation were carried out according to the accepted 

methods of “Methods of field experiment” of the 

Scientific-Research Institute of Cotton Selection, Seed 

breeding and Cultivation Agrotechnologies.

The data obtained from the research results were 

analyzed mathematically and statistically according to 

the method of Method of field experiments” by 

B.A.Dospekhov. 

Field experiments were conducted in the field of "Zarif 

Ota" farm in "Bukhara" province, Bukhara region 

during 2020-2022. According to the experimental 

system, field experiments were carried out in 8 options 

and 3 repetitions (Table 1).

The calculations of the annual and seasonal irrigation 

norms of irrigation in the experimental options for 

irrigation of maize hybrids for 2020-2022 are as follows, 

when soil moisture before irrigation was 70-75-70%, 

seasonal water consumption according to the 1st 

option of irrigation according to the plowed layer of 

the soil in 0-70 cm was equal to 3217 m3/ha, 1st 

irrigation 699.2 m3/ha, 2nd irrigation 599.3 m3/ha, 3rd 

irrigation 610.7 m3/ha, 4th irrigation 599.7 m3/ha, 5th

CONCLUSION 

In total of 8 options, experiments were conducted on 

various irrigation methods of maize hybrids in the 

conditions of weakly salted meadow alluvial soils of 

Bukhara province, i.e. drip and drip irrigation, 

Uzbekistan-601 ECB hybrid compared to NS-6010 F1 

hybrid obtained a higher grain yield when drip 

irrigation was carried out at 70-80-75% pre-irrigation 

soil moisture.
