The study was conducted to determine selectivity of some herbicides to cocksfoot (Dactylis glomerata L.), and their influence on the seed production, during the years 2008- 2010. The trial was set on the experimental field of the Institute of Forage Crops - Pleven, on slightly leached chernozem. As a result of the research the following was found: herbicides Arat (500 g/l dicamba + 250 g/l tritosulfuron) at the dose of 100 ml/ha, Korida 75 VDG (750 g/kg tribenuron-methyl) - 15 g/ha and Cambio SL (320 g/l bentazon + 90 g/l dicamba) - 1250 ml/ha and Grasp 25SK (250 g/l tralkoxyidim) + Atplus at rate of 1000 + 1000 ml/ha had high selectivity to cocksfoot, applied at 2-4 leaf stage during establishing year of the stand, and until the stage of the beginning of shooting up in seed production year. Herbicide Topik 080EK (80 g/l clodinofop - propargyl + antidote) at rate of 300 ml/ha, showed phytotoxic effect to D. glomerata and caused the reduction of seed and dry biomass productivity.

During the period 2008-2010, on the experimental field of the Institute of Forage Crops - Pleven, on slightly leached chernozem a study was conducted with the purpose to determine the selectivity of some herbicides to perennial ryegrass (Lolium perenne L.), and their influence on the seed productivity. As a result of the study the following was found: herbicides for broadleaf weeds control - Arat (500 g/l dicamba + 250 g/l tritosulfuron) at rate of 100 ml/ha, Korida 75 VDG (750 g/kg tribenuron-methyl) - 15 g/ha and Cambio SL (320 g/l bentazone + 90 g/l dicamba) - 1250 ml/ha had high selectivity to perennial ryegrass, applied at 2-4 leaf stage during establishing year of the stand and until the stage of the beginning of shooting up in seed production year. Herbicide for grass weeds control: Topik 080EK (80 g/l clodinafop-prop-argyl + antidote) at rate of 300 ml/ha, applied at the same stage can be applied in seed production stands of perennial ryegrass. Herbicide for grass weeds control - Grasp 25SK (250 g/l tralkoxydim) + Atplus 463 at rate of 1000 + 1000 ml/ ha showed phytotoxic effect on L. perenne and caused the reduction of seed and dry biomass productivity. Realization of the biological potential concerning seed and dry mass yield of perennial ryegrass demands application of selective herbicides Arat, Korida 75 VDG and Cambio SL in control of broadleaf weeds and Topik 080EK in control of grass weeds.

A study was conducted in the experimental field of the Institute of Forage Crops - Pleven on a slightly leached chernozem soil in 2011-2012 to determine the selectivity of some herbicides to standard wheatgrass (Agropyron desertorum (Fisch.) Schultes) during stand establishment and its seed production. The study had the following results: the herbicides Kambio SL (320 g/l bentazone + 90 g/l dicamba) - 1250 ml/ha; Kalam (125 g/l tritosulfuron + 600 g/kg dicamba) - 200 g/ha; Lintur 70 WG (4.1% triasulfuron + 65.9% dicamba) - 150 g/ha, and Axial 050?K (50 g/l pinoxaden) - 600 ml/ha showed high selectivity to standard wheatgrass when applied at the stage of 3-4 leaves during the year of stand establishment; the herbicides Imaspro (69 g/l fenoxaprop-P-ethyl+antidote) and Stelar (50 g/l topramezone + 160 g/l dicamba), each applied at the rate of 1000 ml/ha, caused phytotoxicity (scores from 4 to 6), while Termidor (40 g/l nicosulfuron) - 1250 ml/ha completely destroyed the crop (score 9); the herbicides Kambio SL; Kalam; Lintur 70WG and Axial 050?K applied at the same doses at the stage from spring growth to the beginning of shooting up in the seed production year had a high selectivity to standard wheatgrass and could be applied in seed production stands without negative influence on seed productivity. The herbicide Termidor was very phytotoxic (scores from 3 to 7) and prevented the formation of generative stems.

Each of the species birdsfoot trefoil (Lotus corniculatus L.), timothy (Phleum pratense L.), bromegrass (Bromus inermis Leyss.), orchardgrass (Dactylis glomerata L.), reed canarygrass (Phalaris arundinacea L.) and creeping red fescue (Festuca rubra L.) was grown in the field on 10 plots sampled at weekly intervals in rotation from June 13. Each plot was resampled after 6 weeks and all samples were analyzed for copper, molybdenum and sulfur. In most species, levels of Cu and Mo were highest in the early samplings and decreased with advancing maturity. Second-cut samples tended to be higher in Cu, Mo and S than first-cut samples. The S content was more uniform in the first cycle but increased considerably in the second cycle, especially in reed canarygrass. The ranges in Cu content were 7.4 to 14.1 ppm for birdsfoot trefoil and 3.7 to 11.4 ppm for the grasses. Mo ranged from 1.9 to 8.1 ppm in birdsfoot trefoil and from 1.0 to 6.5 ppm in the grasses. The overall range in S content was from 0.14 to 0.95%. The mineral composition of the crops is discussed in relation to the requirement of ruminants for these three elements.
