The objective of the present study was to investigate some biological peculiarities, productivity of local cv. ꞌMeliferaꞌ Phacelia tanacetifolia, Brassica napus oleifera and Isatis tinctoria, possibility of using harvested biomass as green manures. It has been determined that the green mass yield varied from 2.89 kg/ m 2 (Isatis tinctoria) to 5.84 kg/ m2 (Brassica napus oleifera); the calculated incorporated in sol organic matter from 3.9 (Isatis tinctoria) to 8.1t/ha (Phacelia tanacetifolia), nitrogen 146-280 kg/ha, phosphorus 20- 37 kg/ha, magnesium 10-35 kg/ha, potassium 116-354kg/ha, calcium 50-419kg/ha. Based on our results, we suggest that studied species may be a good nectar source for honeybees and produced biomass- valuable green manures.
