Introduction and agro economical value of sorghum almum in the Republic of Moldova

Аннотация

Taking into account the expansion of areas of degraded soils and the frequency of droughts in our country, it is necessary to mobilize and introduce new species that would ensure production in these severe conditions. The objective of this research was to evaluate the yield and fodder value, biomass calorific value of new species Sorghum almum Parodi in the conditions of Moldova. We have established that plants of Sorghum almum productivity after 2 harvests reached 43.6-44.2 t/ha of green mass or 9.2-11.8 t/ha dry matter. The green mass is used as natural forage and the preparation of silage. 100 kg of natural fodder contains 21-29 nutritive units and 216- 290 MJ/kg metabolizable energy for cattle. To produce solid bio fuel, biomass can be harvested with technical means of fodder collection and used to produce briquettes and pellets, with a gross calorific value of about 18.6 MJ/kg dry mass.
