Agrotechnological Fundamentals of Direct Sowing of Grain Crops in Russia’s ARID Conditions
Abstract
The authors presented the multiyear results of the research on testing the technological complexes
of growing the grain crops with direct sowing in the black earth steppe of Russia’s European part.
In the zonal crop rotations, in comparison with a traditional technology, it did not lead to worsening
of the agrophysical, agrochemical, water and biological soil features, increased the humus content
by 0.55% (NSR05- 0.42 %). In spring, during the crops sprouting, the Р2О5 and K2O quantity
corresponded to 192 and 189 mg/kg of soil, which is 29 mg (17.8%) and 35 mg (22,7%) more than
control. The established least production costs – 2975.1 rub/hectare on an option with direct sowing
of the spring grain crops, which are 499.9 rub/hectare -16.8 % lower than the traditional
technology figures, favored the acquisition of the highest contingent net income of 1220.1
rub./hectare and the profitability level of 41.0%. During the direct sowing of the spring hard wheat,
the highest contingent net income is gained on options with the use of integrated plant protection
and the fertilizer application – 9507.9-9753.9 rub/hectare, which is 3667.6-3913.6 rub/hectare
(62.8-67.0 %) more than the control, and 825.8-3626.9 rub/hectare (9.5-59.2 %) higher than figures
on other options. On the basis of the research conducted, the authors offer a new generation of
technologies of growing the winter and spring wheat and the spring barley, which are built on the
system basis.
