Taking into account the frequency of droughts, expansion of areas of salinized and degraded soils in our country is necessary to introduction and investigated new species that would ensure production in these severe conditions. The objective of this research was to evaluate some biological peculiarities, productivity, biochemical composition (green mass and silage) of C4plants perennial grasses species Sorghum almum Parodi in Moldova’ conditions. We have established that Sorghum almum in the first year develops a strong root system and its aerial part is a bush of 2 - 4 shoots about 2.4 m tall, the plant goes through all phases till full ripening of seeds. In the following years, the resumption of vegetation starts in the end April and a bush can develop up to 20 shoots which attain a height of 3.0 m. The plants regenerate quickly after moving. At first cut the green mass productivity reach 25.0- 42.8 t / ha, the leaves constituting 29.7-41.7 %; second cut - 5.2- 13.8 t / ha and 32.9-40.7 %, respectively. The harvested mass used as natural forage and for the preparation of silage. The silage obtained from Sorghum almum after organoleptic characteristics (smell, color and consistency) and biochemical indexes (pH, organic acids content and its correlation, chemical composition dry matter) largely meet the specific technical requirements of the standard. The nutritive value of 100 kg natural forage was 20-29 nutritive units and 198-290 MJ metabolizable energy. The calculated capacity of biomethane production can reach 272 l/kg organic matter.
