MATHEMATICAL ANALYSIS OF RESULTS OF RESEARCH ON STUDYING INFLUENCE OF WHEAT FEEDING IN THE PHASE OF EMBRYONAL DEVELOPMENT THROUGH LEAVES BY THE METHODS OF B.A.DOSPEKHOV

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.
