METHOD FOR EVALUATING POTENTIAL PRODUCTIVITY OF FARM PLANTS, PREFERABLY COLLECTION SORTS OF SUMMER CEREAL EAR CROPS, DURING CULTIVATION UNDER CLEARLY DEFINED CONTINENTAL CLIMATE CONDITIONS Russian patent published in 2007 - IPC A01G7/00 

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; G_s is hydrothermal coefficient of standard sample cultivation conditions, mm/ C; G_ss 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.
