Bičių įtaka ekologinio ir intensyvaus auginimo vasarinių rapsų pasėlyje

Abstract

Researches done in year 2013 in Aleksandras Stulginskis University experimental station on ecological and conventional spring oilseed rape crops. In order to determine the differences between ecological crops and conventional crops oilseed rape and the attraction of bees towards certain plants, in each field six 2 m² sites of whom three of them where caged. The cages where setup from the 17th of June till the 1st of August. In order to determine the fertility from the 12 sites 30 plants from each site where taken, randomly 10 of them where selected, and determined the average seeds number per pod and 1000 seed weight. It is determined that the essential influence to the crop structure parameters has been made by factor B (bees pollination), and factor A (conventional farming) essential influence was to weight of 1000 seeds
