In 2003–2005 in Lithuanian Institute of Horticulture in trial field for ecologically grown vegetables there were investigated and evaluated plant availability for green manure and estimated it’s influence on ecologically grown onions yield. Investigated plants: barely, barely with undesown clover, summer wheat, peas and outs, rape. Control treatment – black fallow. Was estimated that biomass of plants for green manure leaves in the soil different amount of organic matter. The highest amount of green matter – 43.2 t/ha was get from peas and outs, summer wheat -32.5 t/ha, barely with undesown clover – 30.2 t/ha, lowest – barely and rape (24.5 and 27.0 t/ha). There were not found any significant differences of amount of Thrips tabaci between treatments. Green manure from peas and outs increase onions yield by 3.1%; green manure from summer wheat – 5.7%, green manure from barely with undersown clover – 7.3%. The lowest impact for onion yield has had green manure from barely and rape. The highest number of weeds (191 unit/m²) was found in onions grown after barely with undersown clover, lowest number – 29 unit/m² in onions grown after peas and outs.
