In order to organize a profitable agrotechnology for the cultivation of Melilotus albus in saline area, Melilotus albus’s Kibray variety and Tashkent-1 variety of common alfalfa seeds for comparative study in different versions were studied by sowing in 4 versions, different sowing norms. For each version, valuable farm traits during the vegetation, especially blue mass yield and hay yield were analyzed. Just like that, to each version economical effective ness was studied. In saline areas has been identified an effective version of the sowing norm Melilotus albus.

Enhancing of soil fertility is required for getting high yields from cotton plant, cereals and other crops in Uzbekistan. It may be achieved through implementation of crop rotation, properly introduction of rotation and by the planting of kashkar beda, alfalfa and other bean bearing crops. Planting of Kibray variety of Kashkar beda in strongly salted areas and may be produced high yields than ordinary blue alfalfa. It’s an average green mass yield accounts for 4.0-4.5 tons per hectare, 1 kg green mass contains 17-25 g protein and 0,16-0,20 food units what is a nutritious food for agricultural animals. Beside this, due to its root nitrogen-fixing capability. It may be taken durable high yields from other crops in its planted area.
