MAJOR INFLUENCE AFTEREFFECT TILLAGE CLOGGING CROPS AND PRODUCTIVITY OF WINTER WHEAT
The analysis of the debris of winter wheat depending on the processing of the soil under the predecessor. In 2010, most weeds before processing and before the harvest was after chizelevaniya - 68 pcs / m 2 and 118 units / m2, respectively. Least of all weeds were after plowing - 29 pcs / m 2 and 91 units / m2, respectively. Before cleaning the culture of their numbers increased in all soil treatments by 1.5 times in the cultivation of up to 3 times on plowing. This pattern persists and crude, and the dry weight of weeds. The smallest when plowing - 1.8 g / m2 and wet weight of 0.7 g / m2 dry weight before treatment with the herbicides, and 28.2 g / m2 and 7.1 g / m2, respectively, before the harvest. Most wet and dry weight before treatment after chizelevaniya - 4.3 g / m2 and 1.8 g / m2, respectively, before the harvest, dry weight - 37.6 g / m2 wet weight - 8.0 g / m2. In 2011, prior to treatment with herbicides least weed was after plowing - 11 pcs / m2, and most of all after cultivation - 24 pcs / m2. Before harvesting the winter wheat the number of weeds were everywhere the same - 11 pcs / m2. Prior to treatment with herbicides wet weight of weeds was highest after cultivation - 4.7 g / m2.Suhaya weight was - 0.4 g / m2 after plowing, 0.7 g / m2 after chizelevaniya and 1.0 g / m2 after cultivation. Before cleaning the culture of the wet and dry mass significant differences were observed. On average, the highest number of weeds before herbicide treatment was after cultivation for two years - 51 pcs / m2, the smallest - 20 units / m2, after plowing. In 2010, the winter wheat yields were higher after chizelevaniya - 2.8 t / ha, less after plowing - 2.5 t / ha, after cultivation - 2.7 t / ha. In 2011, the highest yield was after chizelevaniya - 6.8 t / ha, after plowing productivity was lower in all - 6.3 t / ha, after cultivation- 6.6 t / ha. On average, for two years, the highest yield was at aftereffect chisel tillage - 4.8 t / ha, slightly less than after cultivation - 4.6 t / ha and the lowest yield at aftereffect plowing - 4.4 t / ha.
