The objective of the present study was to investigate some biological peculiarities, productivity of local cv. ꞌMeliferaꞌ, Phacelia tanacetifolia, and possibility of using biomass harvested in buding and full flowering period, as green manures and as feedstock for methane production through anaerobic digestion as a renewable source of energy. It has been determined that the green mass yield varied from 3.07 kg/ m2 (bud period) to 5.04 kg/ m2 (full flowering); the calculated incorporated in sol organic matter 3.1- 8.1t/ha, nitrogen 126-182 kg/ha, phosphorus 34-37 kg/ha, magnesium 11.8-27.4 kg/ha, potassium 140.6-353.0 kg/ha, calcium 144.4-419.0 kg/ha. Bio methane production potential varied from 799 to 2073 m3/ha. Based on our results, we suggest that local cv. ꞌMeliferaꞌ, Phacelia tanacetifolia may be a good nectar source for honeybees, and biomass harvested in full flowering period valuable green manures and feedstock for methane production.
