BOTANICAL COMPOSITION OF LEGUME–GRASS AGROPHYTOCENOSIS DEPENDING ON ALIENATION AND FERTILIZATION MODES
There is stated the issue of the effect of different modes of alienation and variants of fertilization on dynamics of botanical alfalfa–grass agrophytocenosis
It was established that the average for the research of 2014–2015 years, the part of leguminouse component of the most valuable herbs that was presented in creeping alfalfa and birds–foot trefoil was high and amounted to 29,5–59,0 % depending on the variant of the experiment.
Among the investigated regimes of using and fertilizing of legume–grass agrophytocenosis at the average of two years, the biggest part of legumes was in the variant of treatment of phosphorous–potassium fertilizers Р60K60 – 51,0–59,0 %.
Early alienation of herbage affected the percentage of leguminouse component in herbage. In variants of hayland in phase of legume branching, cereals booting the part of legumes was 29,5–51,0 %, during mowing in phase ofearly bloom of legumes, cereals earing – 39,4–63,3 % depending on the variant of the experiment.
Among the variants,in which nitrogen fertilizers were treated,the biggest part of legumes was in variant with the treatment of N60 in the form of lime and ammonium saltpeter – 45,9 %. The use of ammonium saltpeter, foliar andsurface carbamide treatment caused the percentage reduction of leguminous components herbage in comparison with the lime and ammonium saltpeter treatment.
