NEW RESOURCE-SAVING TECHNOLOGY OF POTATO CULTIVATION ON SLOPE LANDS OF MOUNTAIN PROVINCE IN DAGESTAN

Abstract

The potato is grown in all natural environment and climatic zones, along from high-mountain slope lands, situated up to 2500 meters above sea level to Pricaspian plains, situated under sea level. The total area of planted potato in the Republic  is 22 thousand hectares, where potato producing  takes more than half of mountain region. The mountain area occupies  2.04 million hectares, which  is 38.3% of total area of Dagestan with highest peaks over 1000 meters above the sea. There are some methods of potato  growing  that  are nearly effective  in  all  climatic conditions, and improve yield and tuber quality. The proposed resource-saving technology enables to reduce expenses by 50 %  for  ploughing,  soil preparation after ploughing,  pre-planting  soil preparation, preserving soil fertility  and  decreasing  erosion  processes.  The results based on experimental data presented were to show the influence of resource-saving technology on growth, development and yield augmentation when growing on slope lands of mountain province of Dagestan. Advantages of this resource-saving technology and its economic efficiency were shown as well.
