Influence of Different Farming Systems on the Changes of Segetal Flora in Heavy Loam Soil

Darbe nagrinėjama ekologinės ir tausojamosios žemdirbystės sistemų įtaka žieminių kviečių pasėlių segetalinei florai bei žieminių kviečių produktyvumui, esant skirtingam dirvožemio humusingumui.Master thesis presents the research data on the influence of different farming systems on the changes of segetal flora in heavy loam soil.Žemės ūkio akademijaVytauto Didžiojo universiteta

Influence of different farming systems to segetal flora changes are diffucult soil

Cropping systems weeds in winter wheat field were carried out in 2016 Lithuania Agriculture and Forestry Science Center (LRCAF) Research Station. Test fields are located in the sub-basin Musa, Musa - Nemunelis plain heavy loam soil. Factor A: farming systems: organic farming and sustainable agricultural system. Factor B: low and medium humus soil. Research has shown that in the spring the biggest winter wheat weedinnes was cropping systems with an medium content of humus, while the harvest studied farming systems in weeds evenly on both humus backgrounds. In the spring of winter wheat fields in the greatest number of weeds (109 number m"2) detected sustainable agricultural system II, the lowest (66 number m"2) - sustainable agricultural system I. In both farming systems humus content was low. Before harvesting the most weed (47 number m"2) of the organic farming system II. Fields with a low content of humus, the least detected weed (35 number m"2) - sustainable agricultural system II, as well as a low content of humus. It was found that the number of weeds in winter wheat, per square meter, the harvest was lower than in the spring, which suggests that the crop of weeds decreased with the increase of winter wheat smothering resolutionVytauto Didžiojo universitetasŽemės ūkio akademij
