Abstract. Violation of the optimal timing of field work and irrational structure of acreage leads to a decrease in crop yield. The purpose is to show ways to improve the efficiency of grain production due to earlier terms of wheat harvesting. The objects of the study were operational data on the timing of field work and the yield of grain crops in the agricultural sector of the Kurgan region and in the fields of the Kurgan research Institute, weather data. Common methods of comparative, statistical, factor, and correlation analyses were used. Results. It was found that the most favorable conditions for harvesting grain crops are formed in August. At the same time, as of September 1, 2019, 21 % of the area of grain crops was removed in the Kurgan region, and 71 % as of October 1. The yield of grain harvested in September was 5.7 t/ha below removed in August, loss of income – 6.2 thousand rubles/ha. Price for grain sold in September, is often lower than in August, and another minus 1.5 thousand rubles. The Early cleaning provide earlier crops. For more effective optimization of work terms, it is proposed to keep their records and analysis in the e-book of field history developed at the Kurgan research Institute. It was found that with minimal availability of agricultural machinery, the yield on fields in different hydrothermal conditions varied slightly due to the use of a wide range of sowing dates from May 2 to May 31 and the rational structure of varieties. About 10 % of crops under winter wheat allowed to start harvesting 2–3 weeks before spring and it is more profitable to sell grain. Agricultural producers are recommended to optimize the terms of harvesting spring wheat due to earlier sowing dates, taking into account the validity for each field and the introduction of winter wheat into circulation. The scientific novelty lies in the analysis of the conditions of sowing and harvesting operations in the economy that have developed over the past 5 years in the context of each field.
Keywords: terms of sowing and harvesting of grain crops, conditions of grain maturation, spring and winter wheat, field history book, accounting for the terms of field work, income, price, profitability, economic efficiency.
