Summary |
Study
is devoted to development of winter wheat optimal water
and nutrient regime providing high yield under rational
irrigation water use in conditions of North
Tajikistan, planning and management
by water-nutrient regime of wheat and irrigated lands productivity
under water resources deficit. Plot altitudes are 13 50-1400m.
Climate is characterized by high precipitation rate in fall,
winter and spring. Soils-bright and typical serozems made
of loam. Area is 2ha, land use efficiency is 0.92. Irrigation
canals are earthen with efficiency 0.85-0.90. Plot is equipped
with means of water account. Study shown that optimal irrigation
regime is irrigation under soil moisture 70±3% of normative
moisture in combination with rational norm of fertilizes
application. Bio-climatic coefficient (ratio between net
irrigation norm and water balance deficit) and
relationship between cotton water consumption and
irrigation regime and between wheat yield and bio-climatic
coefficient and factor of crop productivity are found. Recommendations
are given. |
