EFFECT OF SEEDLINGS AND FERTILIZER AMOUNT ON PHOTOSYNTHETIC PRODUCTIVITY OF WHEAT

Abstract

The method of presuming and foliar treatment of spring wheat crops with
various grow the regulating preparations should be referred to a number of
promising techniques that provide increased productivity and quality of crop
production. The conducted studies have shown that the highest values of
germination energy and laboratory germination during presuming treatment of
seeds with experimental preparations were found in the option Megamix-zinc. The
use of various modifications of the Megamix preparation for presowing seed
inoculation contributes to an increase in the field germination of the experimental
crop according to all options, depending on the year of the study. On average, over
the years of the research, the used modifications of the Megamix preparation and
their combination with mineral fertilizers contribute to an increase in productivity
by 0.51–3.23 kg/ha, the best result over control is ensured by the use of the
Megamix-zinc modification compared to complex sulfur-containing mineral
fertilizers, which is 11.83 %. Thus, the use of experimental preparations and their
combinations with complex mineral fertilizers has a positive effect on production
processes which ultimately contributes to an increase in the productivity of spring
wheat.
