Summary |
Studies
are dedicated to the development of biologically optimal
regime of forage beet irrigation providing maximum crop
yield and high effectiveness of water-land and other resources
use in conditions of Central Tadjikistan. EPP is located in Gyssar valley at the altitude 641-1215 m. Soil
- semi-loam. Ground water table - 1.5-3 m, mostly fresh
(up to 1 g/l) or slightly saline (1-3 g/1). EPP area - 1.5
ha. Irrigation source - Big Gyssar canal, water salinity
degree is at least 0.7 g/1. Irrigation network - in earthen
channel, efficiency 0.85-0.90. Plot is equipped by water
account means. In result of studies it has been established
that biologically optimal and economically expedient forage
beet irrigation regime under conditions of dark gray desert
soils of Gyssar valley is irrigation with soil humidity
at level 70% normal humidity during growing period. To perform
this purpose 7 irrigations are carried out according to
scheme 2-4-1 with irrigation norm 5700 m3/ha. 150-160
t/ha root crops and 18-20 t/ha vegetable tops. |

#42, 1997 Results of studies are given on optimization
of forage beet irrigation regime in conditions of dark
gray desert soils of Gyssar valley. Data are given on irrigation
terms and schemes, forage beet irrigation norms and crop
yield capacity. Recommendations for production are given. |
