are decreasing from year to year due to limited water supplied with excessive water, with low evaporation from
resources. Analysis shows that over the years, the demand the soil and water does not disperse across the field.
for water is increasing, so we need to use a drop of water and To date, M.Khamidov, B.Matyakubov, M.Sarimsakov,
use it wisely.
Sh.Azizov, SA Mamatovs are doing research on the use of
Drip irrigation system is a pressure irrigation system drip irrigation technology. They were used only when muddy
designed to supply the plant with the required amount of water was discontinued, and we had direct use without
water to its root surface in the required amount of time. interrupting muddy water.
With the introduction of drip irrigation, water use and crop Results of the study: The implementation of drip irrigation
irrigation have a number of advantages. With the technology of intensive orchards on the area of 3 hectares in
introduction of technology, the main goal is to save water for the educational and scientific center of Bukhara branch of
drip irrigation, water is only given to the root zone of the the Institute for Drinking Water. Given that till now drip
field, and other areas remain dry. The irrigation regime is irrigation is only used with clean water, direct drip irrigation
appropriate for the water demand of the plant and is not with muddy water is practiced for the first time.
Irrigation norms and yield of vineyards

During the experiments, water savings were up to 40%, while in conventional irrigation water consumption was 4200 m3 / ha,
and for drip irrigation the water consumption was 2500 m3 / ha (Figure 1). Fertilizers saved 52% compared to usual. At the
beginning of the vegetation season, the average ground water level was 194-198 cm, and in the middle of the growing season,
between July and August, groundwater levels were about 175-181 cm. The soil weight was 1.31 g / cm3 in 0-30 cm of plowed

soil, 1.39 g / cm3 in subsoil (30-50 cm) and 1.40 g / cm in 0-100 cm layer.
