Power assessment of resource-saving technologies of cultivation of grain crops in the conditions of the forest-steppe of Krasnoyarsk region

Power efficiency of cultivation of grain crops on resource-saving technologies in the conditions of Krasnoyarsk forest-steppe is shown. The productiv-ity of grain crops has fluctuations depending on the way of soil processing. Minimizing to some extent promotes the formation of higher productivity. Bar-ley in the efficiency concedes to wheat and oats. At introduction of ammonium nitrate average yield of grain crops is the least on option of direct crops. The analysis of the level of expenses and profitabil-ity of the production of wheat, oats and barley showed that the use of resource-saving technolo-gies of soil processing reduces labor costs by 35.5-49.1 %, the consumption of fuel and lubricants de-creased by 40.3-64.2 %. Profitability level at direct crops was 140 %, on the option with disking it was 129 %. The use of ammonium nitrate led to the growth of profitability level on the option of direct crops for 3.8 %, on the option with the minimum pro-cessing by diskator for 23.7 %. The ways of soil pro-cessing have various power efficiency. Lower values of production expenses were per unit area observed at direct crops. The use of ammonium nitrate raised expenses to 7740 rub/hectare. On the option with disking without fertilizers production expenses made 7795 rub/hectare, with the use of ammonium nitrate of expense grew to 8396 rub/hectare. The ways of processing of the soil have various power efficiency. Lower values of production expenses were per unit area observed at direct crops. In this option without application of mineral fertilizers the expense made 7139 rub/hectare. The use of ammonium nitrate raised expenses to 7740 rub/hectare. On the option with disking without fertilizers production expenses made 7795 rub/hectare with the use of ammonium nitrate of expense grew to 8396 rub./hectare. The greatest production expenses were received when plowing, 8877 and 9479 rub/hectare respectively. In general the application of mineral fertilizers at cultivation of grain crops reduces product cost. Such regularity is caused by considerable increase of the harvest at importation of ammonium nitrate.
