| Outline of Final Research Achievements |
Although the availability of soil nutrients on combination of no-till and hairy vetch cultivation was increased, the improvement of the working efficiency on no-till seeding in early winter was not detected. It was shown that the growth and the yield of wheat were superior in addition of hairy vetch residue in pots tests. After snow melt , however, the number of wheat seedlings seeded in early winter was less than that of spring seeded wheat. The ratio of normal seedlings was decreases under the snow in the case of hairy vetch residues incorporation. The results of this study were exhibited less advantage to the combination of hairy vetch cultivation and no-till sowing of spring wheat in early winter. We are examining for the effects of autumn plowing.
