Abstract:

Abstract Different sowing rates, row spacing, optimal and reasonable mixtures of herbicides were investigated for the seed production of the Estonian fodder galega Gale (Galega orientalis Lam.). The control of dicotyledonous weeds with herbicides is well justified in the year of sowing because the control remains insufficient in the years of seed production. However, the control of weeds in the years of seed production diminishes the expenditures for seed gathering, drying and cleaning. The control of couch grass is necessary to avoid ergot sclerotia in seed production and gives good results in the years of seed harvesting. The average seed yield of fodder galega was 259 kg ha-1 Desicant Basta 150 SL (glyfosinate-ammonium 158 g l-1) with rate of 1.0 l ha-1 was used before seed harvesting in order to dry the green parts of plants, to favour uniform ripening and to diminish the losses in seed harvesting, which gave an extra yield of 35%. Due to a higher competative ability of weeds, it is expedient to use a bigger sowing rate in the ecological farming, i.e. 10 kg ha-1.
