Abstract:
Complex investigation on the
effect of Thiourea, Galmet and Thiogalmet
compositions on water status, intensity of
photosynthesis, water use efficiency, growth
and yield of ‘P458’ maize plants under
conditions of natural humidity in field trials
was performed. The beneficial effect of seed
and foliage pre-treatment with Thiourea,
Galmet and, in particular, the new chemical
composition Thiogalmet on plants’
biological processes conditioning a better
realisation of the physiological processes
associated with plant growth and
productivity was established. A significantly
greater positive impact of Thiogalmet on the
optimisation of hydration degree, water
retention capacity, stomatal conductance for
CO2/H2O, assimilation, water use efficiency,
plant growth and productivity was recorded.
There was an additive action of Thiourea and
Galmet in the composition of the Tiogalmet
preparation. Thiogalmet increased the yield
per unit area and improved the commercial
quality of the grain. Treating plants with
Thiourea, Galmet and Thiogalmet ensured a
27.20, 52.08 and 68.20% yield increase,
respectively, compared to the plants in the
control variant. Therefore, a major effect
was registered in the plants treated with the
new composition. The obtained information
demonstrates the possibility of mitigating the
adverse effects of drought on the
physiological response and production by
applying antioxidants.
