Abstract
The article presents the results of scientific research on the effect of soil treatment intensity on weed infestation and the yield of oat and pea field grain in single-species and mixed crops for organic production during 2013-2015. From the minimization of the autumn plowing of the soil (replacement of autumn plowing by 20-22 cm in autumn small discs by 10-12 cm), the weed infestation of oats in the tillering phase increased from 15 to 25 pieces / m2 or by 67%. At the time of ejecting panicles from oats from the combination of pre-emergence loosening of the soil with autumn plowing and autumnal small discs, the weed infestation decreased on average in three years - by 30 and 24%, respectively. Soil cultivation reduced the weediness of crops and largely affected the yield of oats and peas field in both single-species and mixed crops. The maximum grain yield of 2,61 t / ha was provided by a variant where autumn plowing by 20-22 cm was supplemented by loosening the soil 6-8 cm in single-species oats. The maximum total yield of grain of oats and peas field was 2,69 t / ha, when mixed crops were sown.
