Production and some energy indicators in semi-desert biogeocenosis of the Ganykh-Airichai valley of Azerbaijan

The results of phytoproductivity in dynamics and some energy indicators of Artemisetum-Ephemerosum and Alhagietum-Artemisosum on the territory of the Ganykh-Airichai valley of Azerbaijan are presented. These are typical semi-desert coenosis. Analysis of quantitative indicators of energy consumption in plant communities over the period of research showed that 2 types of weather and climatic conditions determined 2 contrasting periods of development. Data on the aboveground and underground biomass in the studied communities are given. A comparative analysis has been carried out.
