AMMONIUM NITRATE AND DIALEN EFFECT ON THE LEAF SURFACE SQUARE AND BIOMASS OF WHEAT PLANTS

Abstract

To cause herbicide toxic effects on grain crops to go down combined preparations are applied, such as Dialen, Chistalan, Super Dialen, Dimax, Super Biolan and others. However, these herbicides produce toxic effects on plants. Agroecological factors do not have the same effects on leaf square in the crops and biomass accumulation. Leaf surface accumulation in wheat plants in all the variants corresponded to the classical curve of accumulation dynamics. Maximal expanded wheat leaf surface in the control, in the variant with ammonium nitrate treatment, in that with Dialen as well as with Dialen in the background of ammonium nitrate were in the phase of wheat plants shooting. Minimal value of wheat leaf surface in all the variants was in the phase of plants anthesis. Wheat plants accumulated biomass minimally in the control variant throughout the entire vegetation. The variant with Dialen ranks second for the biomass accumulation, the one with ammonium nitrate ranks third. The maximal wheat plants biomass accumulation was observed in the variant with Dialen applied in the background of ammonium nitrate throughout the entire vegetation.
