The efficiency of resource-saving tillage in the bogara of Uzbekistan

The study was conducted at Galla-аral Branch of Uzbek Research Institute of Grain and Legume Crops. The study was on “Reduction of load on the use of natural resources as a result of competing cultivations methods for unirrigated arid lands in mountain, semi-arid and desert landscapes of Uzbekistan”. The study revealed that zero tillage is effective only in a grain-fallow-hoed crop rotation with a short rotation (naked fallow - wheat - wheat) in the bogara. Zero tillage with direct seeding and no-till technology “AGROLEAD” showed higher yields of wheat grain in comparison with the tillage with a single-furrow plow conducted in the autumn. It was due to higher plant population rate and better water regime of soils. Due to nitrogen-fixing ability, leguminous crops (chickpea) are good predecessors for wheat under conditions of bogara. The optimal tillage system is the most important agrotechnical measure to obtain stable and high yields of grain and other products in the bogara.
