Feeding value of desert, semi-desert and arid plain winter pastures of the North-Western part of Azerbaijan is considered in the article. Data on dynamics of fodder resources and features of the major plants of the winter pastures of the region are given. A chart-scheme of main types of vegetation of winter pastures is cited. A brief evaluation of present-day condition of pastures and recommendations in the further exploitation are given. Natural vegetation of arid steppes, deserts and semi-deserts of Azerbaijan serves as satisfactory forage during the winter, spring and autumn and it is considered as winter pasture. These fodder pastures have enormous significance for rural economy of the republic as a cheap forage base to develop and strengthen efficiency of cattle-breeding. They provide cattle-breeding industries with forage within 6-8 months in a year (October to May). Dynamics of fodder resources and properties of dominating plants of winter pastures of the region is considered in detail in the article. Particularly geobotanical classification of the deserted, semi-deserted and arid steppe pastures of north-western part of Azerbaijan is provided. A card-scheme of the basic types of vegetation of winter pastures is adduced. Brief evaluation of the state of pastures and recommendations in the further exploitation are given. 2. Materials and Methods The research was carried out by the standard methods of geobotany (Prilipco, 1954) and had a detailed-routing and semi-stationer character. Taking into account that geobotanical researches are periodically carried out every 5 years average data have been given in the article recently. Desert, semidesert and arid plain cenoses of the North-Western part of Azerbaijan served as objects. The investigation was carried out in the period of active vegetation and fructification of vegetation, i.e. in spring (April to May) and in autumn (October to November). In the abovementioned cenoses that served as pasture plots were put in accordance with the methodological recommendations. The description on the plots was carried out by compiling of a plant list by abundance indication of each species, phenophase, pasturing and other geobotanical indices (height, vitality, project covers and phonological observations.) The harvest was defined twice in spring (April to May) and in autumn (October to November) to ascertain dynamics of gross feedstock during a year. Productivity of grassy vegetation was taken into account by the method of cut from the plot with dimension of 140x40cm (0, 4m 2 )/ha. 3. Results and Discussion
