Influence of mineral fertilizers on yielding capacity and quality of soft spring wheat grain
Received: March 13th, 2021 ; Accepted: June 6th, 2021 ; Published: June 10th, 2021 ; Correspondence: [email protected] aim of the study is optimization of nutrition system for soft spring wheat plants
through the use of mineral fertilizers in order to obtain high quality grain with simultaneous yield
increase. Different doses of mineral fertilizers were tested in the study. The object of study was
a variety of soft spring wheat ‘Uliublena’. The structure of the crop was determined by the method
of selecting sheaf samples from each accounting area. The leaf surface area was determined by
calculation method. According to the results of research, yield capacity of soft spring wheat on
average ranged from 2.43 to 4.51 t ha-1
. The highest index of gluten amount was obtained in the
variant with fertilizers dose N64P64K64 - 28.19%, which is higher than in the variants with fertilizer
doses N16P16K16 and N32P32K32 by 6.11 and 0.15%. The highest increase in the yield of soft spring
wheat grain (2.08 t ha-1
) was obtained with application of N64P64K64, slightly lower yield increase
was obtained with application of N32P32K32 - 1.64 t ha-1
, and N16P16K16 - 0.99 t ha-1
comparing
with the control. With fertilizer dose of N64P64K64 soft spring wheat provided the maximum
yield - 4.51 t ha-1
, gluten content - 28.19% and protein content - 14.21%
Adaptation of various maize hybrids when grown for biomass
Received: January 10th, 2022 ; Accepted: May 1st, 2022 ; Published: May 10th, 2022 ; Correspondence: [email protected] aim of this research is to optimize growth and development of maize for biomass
by selecting maize hybrids to fulfill their productivity potential. The following maize hybrids
were the subject of research: Forteza, DM Native, DM Skarb. The greatest height of plants was
formed in the interphase period of milk-wax maturity of grain in hybrid Forteza - 286.4 cm. In
hybrid DM Native the height of plants was - 271.2 cm, hybrid DM Skarb - 263.6 cm. Weight of
one plant of hybrids studied during the maize growing season ranged from 442 g to 760 g. Thus,
the largest mass of maize plants was recorded in the milk-wax maturity stage. It was the largest
at the hybrid Forteza and amounted to 760 g, that is more than at the hybrid DM Native for 3.4%
(26 g) and at the hybrid DM Skarb for 6.6% (50 g). The average crop yield of the hybrid Forteza
for the period of research was 55.1 t ha-1
. Hybrids DM Native and DM Skarb provided this
indicator at the level of 50.6 and 45.7 t ha-1
respectively. Hybrid Forteza provided a maximum
crop yield 55.1 t ha-1 with plant height 286.4 cm, assimilation surface of one plant and a crop
0.59 m2
; 42.8 thousand m2 ha-1
and plant weight 760 g
