The productivity of grain-fallow rotation sequence in dependence of tillage technology
Abstract
The analysis of the advantages of moldboard, subsoil and minimum tillage shows the necessity to study a combined tillage. The trials have been conducted in a research department of Bashkirsky RIA, located in the steppe Zauralie of the Republic of Bashkortostan. The climate of the area is dry; the amount of precipitations with the temperature of 100 is about 150 mm. The soil is medium-humus, heavy loamy black earth (chernozem). The experiment included moldboard plowing on 20-22 cm for wheat, 25-27 cm for peas; subsoil plowing (chisel tillage) on 25-27 cm for wheat and 28-30 cm for peas; combined plowing (disk tillage) on 8-10 cm for wheat and chisel tillage on 28-30 cm for peas. The study of the results showed a positive effect of subsoil and combined tillage on the improvement of water-physical properties of soil and on grain productivity of grain-fallow rotation sequence. The variants of productivity of spring wheat and peas in dependence of the annual humidity and tillage technologies have been analyzed. The high efficiency of a combined tillage for both increase of grain productivity and decrease of tillage costs has been established.
