The effect of basic tillage method soil and the aftereffect of nitrogen fertilizer on yield of spring wheat crop rotation from distance of forest shelterbelt

Abstract

In chernozem droughty steppe of Volga region in the field of long-term inpatient experience they have been analyzed changes in yields of spring wheat were seeded on Millets from distance of forest shelterbelt by basic tillage method soil on the background of aftereffect of nitrogen fertilizers and natural fertility on background. When finding plots of forest shelterbelt at a distance of 130 m for all treatment variants, as against the background of the aftereffect of nitrogenous fertilizers and natural fertility on the background of the yields of spring wheat word exceeded tended yields plots, which were from forest strips at a distance of 70 and 10 m, especially the first one. Nitrogen fertilizers in the aftereffect for all treatment variants regardless of distance finding plots of forest shelterbelt increased crop yield in a substantial amount. When finding plots of forest shelterbelt at a distance of 70 and 10 m after shallow plowing on the background of the aftereffect of nitrogenous fertilizers yield of spring wheat it was the same as after deep plowing. When removing from forest shelterbelt from a distance of 10 m at a distance of 70 m marked decrease and at a distance of 130 meters, on the contrary, increase the yield of spring wheat for all of basic soil treatment, as on the background of the aftereffect of nitrogenous fertilizers and natural on fertility background. Application disking and subsurface plowing as against on the background of the aftereffect of nitrogenous fertilizers and natural fertility on the background, especially on the second background reduces the yields of spring wheat compared with deep moldboard  plowing, regardless of the distance from forest shelterbelt. The energy efficiency ratio in the cultivation of spring wheat on natural fertility on the background the annual plowing has a clear advantage over the annual disking and annual subsurface plowing, and near to the annual shallow plowing.  On the background of the aftereffect of nitrogenous fertilizers in the cultivation of spring wheat in finding plots of forest shelterbelt at a distance of 70 and 10 m by energy efficiency ratio the annual subsurface plowing and the annual shallow plowing have some advantage before the annual plowing, and when it finds the plots of forest shelterbelt at a distance of 10 m variant with the annual disking is near to the control.
