Abstract:
Research of methods of soil maintenance in interlinear area of orchards had been performed during 2011 and 2012 on two locations: experimental field of Agricultural Institute of RS in Delibasino Selo and Stranjani, places near Banja Luka. In this research four dedicated grass mixtures and ryegrass for havy trample and utilization had been used in two locations in a pure sowing system. Experiments had been set in four repetitions on a brown valley soil (in Delibasino Selo) and vertisol (in Stranjani). In Delibasino Selo location we had applied a classic soil processing and in Stranjani location reduced soil processing. Also, before sowing on both locations hydrogel had been introduced. During biennial research we determined: floristic content of weed community in orchards, green and dry mass yield from surfaces on which hydrogel had been used and surfaces without usage of hydrogel, number of mulchig during vegetation period, botanical content of green mass of first swath, and covering - density of crops at the end of vegetation period. From the surfaces where hydrogel had been used and those without hydrogel usage, soil samples had been taken for determination of diferences in moisture content between them in soil laboratory. Green biomass and dry mater yield in a first swath of 2011 in Delibasino Selo location had been higher in all researched variants on surfaces where hydrogel had been used. On a location where reduced soil processing had been applied in green biomass of first swath a part of other plant species (weed) had been higher during biennial period of research. Content of moisture in plant roots area on both locations had been higher on variants where hydrogel had been applied before lawn establishment. The highest covering – density of crops on Delibasino Selo location had a mixture Lolium perenne, Phleum pratense, Festuca rubra (81,42%), and on Stranjani location smješa Lolium perenne, Phleum pratense (91,21%).
