method u043eu043fu0440u0435u0434u0435u043bu0435u043du0438u00a0 field crop productivity at different dates of planting, consisting of an assessment of the spring summer period for meteorological parameters, separate u0430u044eu0449u0438u0439u0441u00a0 so that, with a view to u0432u044bu00a0u0432u043bu0435u043du0438u00a0 optimum time of sowing field crop for meteorological and technological parameters, the productivity of u0440u0430u0441u0441u0447u0438u0442u044bu0432u0430u0435u0442u0441u00a0 with the deficit of soil moisture, the moisture u0434u043bu00a0 plant growth.water consumption per unit of product, and the obtained correction coefficients and the calculation of productivity u0432u0435u0434u0435u0442u0441u00a0 as follows;where is the productivity of u00a0u0440u043eu0432u043eu0439 wheat, c / ha;;rp is the supply of available soil moisture, mm;;u0434u0442u043a moisture deficit during the period u0442u0440u0443u0431u043au043eu0432u0430u043du0438u00a0 - u043au043eu043bu043eu0448u0435u043du0438u00a0, mm;;s - precipitation during the growing season, mm;;nam is the lack of moisture during filling, mm;;to the water in one c grain, mm;;bc - coefficient regression u0434u043bu00a0 weeds;;ms mass u0441u043eu0440u043du00a0u043au043eu0432, g / m2.;the pcb is the time of sowing.;ct - heat coefficient;;r is the total lack of moisture during the growing season, mm.
