The article contains information on water consumption in the field of experience of soybeans grown as a product that is 
repeated in various irrigation procedures. 

 

 

INTRODUCTION 

The role of irrigation water in agricultural 
production and food security around the world is 
invaluable.  According to the International Food 
and Agriculture Organization (FAO), in 2020 the 
world gross harvest of oilseeds is projected to 
grow at the level of the world population. 

  Correct determination of the norms and terms 
of watering the shade, taking into account the 
soil and climatic conditions, depending on the 
physiological requirements of the plant, has a 
positive effect on the quantity and quality of the 
resulting grain. 

THE MAIN FINDINGS AND RESULTS 

  In recent years, the country has achieved high 
yields as a result of the correct selection of 
soybean varieties for various soil and climatic 
conditions, as well as the development and 
application of agricultural techniques for 
growing soybeans with high yields and grain 
quality.  One of the important tasks of the 
Strategy for the Development of Agriculture of 
the Republic of Uzbekistan for 2020-2030 is 
“ensuring the use of intensive methods in 
agricultural production, primarily modern 
agricultural technologies that save water and 
resources.” 

ABSTRACT  
 
The article examines the water consumption for harvesting 1 centner of soybean variety “Tomaris”, grown as 
an auxiliary crop, under various irrigation regimes. 
 
 
KEYWORDS: - Shade, re-sowing, shadow variety “Tomaris”,  LFHC, pre-irrigation soil moisture, irrigation 
rate, seasonal irrigation rate, duration of irrigation, irrigation schedule, water balance, water consumption, 
soil moisture reserve.

  Based on the above, in 2017-2019.  Field 
experiments were carried out in order to develop 
optimal shade irrigation regimes and obtain 
scientific conclusions in the conditions of 
meadow soils of the Andijan region. 

  In the territories freed from winter wheat, the 
soil moisture before irrigation of the Tomaris 
variety as a secondary crop is about 65-70-65%, 
70-75-65% and 75-80-70% in relation to the  
LFHC,  Research Institute of grain and 
leguminous crops  carried out in the conditions 
of meadow soils.  In the experiment, there was 1 
option 9.6 meters wide, 50 meters long, the area 
of each section is 480 m2, the calculated area is 
240 m2, in four turns, in one tier. 

  Over the years of the experiment, the inflow and 
outflow of water from the experimental field was 
monitored.  The water balance consists of the 
input and output parts of the water norm, set 
during the shelf life of the plant.  The water 
balance of the field is made up of the norm of 
water used for irrigation of the water intake part, 
precipitation during the period of operation, and 
groundwater.  The water balance of the field 
consists of the evaporation of water from the soil 
during the application period, water used for 
transpiration by plants, water disturbed in the 
lower soil layers as a result of excessive 

irrigation, and irrigation water leakage to other 
territories  and water assimilated by plants. 

  Over the years of the experiment, samples were 
taken to determine the moisture reserve from 
the 0-170 cm layer of the soil of the experimental 
field at the beginning and end of the application 
period for the study of the water intake part of 
the experimental field, precipitation during the 
period of application and seasonal irrigation 
rates used for irrigation.  The income part of 
water consumption was studied according to the 
following formula. 

 

 

Here: total water consumption of the E-test field, 
m3 / Moisture reserve at the beginning of the 
application period in the soil layer NH-0-170 cm, 
m3 /  WK - moisture reserve at the end of the 
application period in the soil layer 0-170 cm, m3 
/;O- Total precipitation for the period of 
operation, m3 /;MO - Seasonal irrigation rate, m3 
/; 

  The results of scientific research on water 
consumption for harvesting 1 centre of grain, 
depending on the irrigation regime of soybean 
varieties by years, are shown in Picture 1.

Picture 1. Water consumption for harvesting 1 
centner of Tomaris soybean cultivated as a 
secondary crop, (m3 /) 2017 

   According to the Andijan branches of 
Uzhydromet, the amount of precipitation during 
the shadow period, grown in 2017 as a 
secondary crop, was 71.7 mm.  Soybean grain 
yield before irrigation, soil moisture 65-70-65% 
in relation to  LFHC is about 19.3 c / soil fertility 
before irrigation is about 70-75-65% in relation 
to  LFHC, version 27.0.  c / ha nei It was found 
that the variant with irrigation of the order of 80-
70% was 22.8 c /.

2017, at the beginning of the application period, 
the moisture reserve of the experimental field
