Abstract:

Based on the results of field experiments in 2015-2017 on winter soft wheat varieties, the yield error was 0.64-0.98 kg / ha (НСР05 factor A), and the yield error on application of the urea norm was 0.45- 0.69 kg / ha (HCP05 factor B), which allows us to consider the conducted research reliable.

The result determined by mathematical analysis according to the method of B. A. Dospekhov [4], the minimum difference was up to 0.98 kg / ha, which allows the introduction of large-scale practical farming with urea solutions physical 40 kg / ha per 300 l / ha of water in the beginning phase embryonic development of varieties of winter soft wheat Yaksart and Gazgan through the leaves.
