FIELD: agriculture, in particular, forecasting of yield and evaluation of grain quality, as well as efficiency of agronomical measures practiced on introduction of new sorts. ^ SUBSTANCE: method involves determining optimal time, seeding norms and seeding procedures; setting total of average daily temperatures beginning from seeding time to termination of vegetative phase; setting seeding norm for forming density of crop; calculating hydrothermal coefficient for "seeding-harvesting" period; determining productivity planned by calculations; providing on-time seeding of standard (zoned) early ripened sort of, for example, summer wheat Albidum 28; setting optimal seeding norm, actual total of positive temperatures beginning from seeding time to grain formation time, value of hydrothermal coefficient; determining potential yield of collection sort samples from formula: where y is grain yield, t/hectare; a is coefficient taking into account seeding time deviations as compared to standard time; S is actual total of positive temperatures beginning from seeding time to standard sample grain formation time, C; Gs is hydrothermal coefficient of standard sample cultivation conditions, mm/ C; Gss is hydrothermal coefficient of growing conditions for sort samples before introduction, mm/ C; b is coefficient taking into account soil-and-climate conditions; c is coefficient taking into account productive soil moisture resources during "seedlings-grain formation" period. ^ EFFECT: increased productivity and improved quality of grain. ^ 4 dwg, 21 tbl |
