Post-harvest siderates impact on the weed littering of Maize

The problem of post-harvest winter rapeseed crops usage influencing siderate and green fodder, oil radish impacting siderate and forage, root and post-harvest remains of winter wheat, and also cattle manure (40 t/ha) influencing the weed littering of maize and grain under conditions of grain-cultivated crop rotation has been revealed by PS of NUBiP of Ukraine - Agronomic research station. It has been proved that the cleanest crops of maize on the typical low-humus and light-loamy black soils remained in the variants where its predecessors were oil radish and winter rape on green fertilizer. Compared to control (root and post-harvest remains of winter wheat), weed amount decreased by 54 and 37% accordingly. Oil radish had a sufficient toxic effect on weeds as it was evidenced by their weight which in this variant decreased under shelf cultivation by 72% and under chisel cultivation - by 61%. Higher yield of maize for both chisel and shelf cultivation was forming in variants with oil radish for siderate and green fodder. The yield increase was 0.3-1.0 under shelf cultivation and 0.7-1.2 t/ha under chisel cultivation.
