Influence Of New Types Of Horizontal Ditches On The Growth, Development And Yield Of Winter Wheat In Saline And Groundwater Surface Soils
Keywords:
Abstract
The average salinity of Jizzakh region in the vicinity of groundwater (1.5 m) under the influence of a newly built closed bed ditch, winter wheat is irrigated 3 times during the season, the current irrigation rate is 823-933 m3 / ha. The norm of seasonal irrigation was 2586 m3 / ha, and the grain yield of winter wheat was obtained depending on the experimental areas, ie the area of the new construction (experimental variant) and the old type of irrigated area (control). At the same time, the average grain yield in the experimental field was 43.2 t / ha, and in the control field - 40.1 t / ha.
