| Summary: | The article presents the results of the research into photosynthetic activity of soy plantations under the application of various
types of fungicides and inoculant Rhizoactive.
The object of the research is soy plants of cultivar Anushka and microbial preparation Rhizoactive. Concentration of chlorophyll a and b was investigated at the phase of blossom ending and formation of beans using spectrophotometer according to the
methods developed by Z.M. Hrytsaienko and co-authors. Parameters of net productivity of plantings photosynthesis were
calculated according to the methods of A.O. Nechyporenko.
It has been found out thatweather and agronomic conditionsas well as biologically active substances (different types of
fungicides and microbial preparation) influence the productivity of photosynthetic processes in soy plants. It has been
established that under application of fungicides Akanto Plus 28 KC, 1.0 l/ha, Amistar Extra 280 SC, KC, 0.75 l/ha, Bamper
Super 490, KE, 1.5 l/ha, Impact K. 0.8l/ha, Koronet 300 SC, KC 0.8 l/ha against the background of inoculant Rhizoactive
(2.0 kg/per 1 ton of seeds) the concentration of green pigments (chlorophylls a and b) increases considerably, which
promotes the increase in the parameters of net productivity of photosynthesis. This is due to the fact that combined
application of fungicides and inoculant has an optimal effect on soy plants: application of fungicides decreases the incidence
of plants diseases and use of inoculant improves the level of mineral nutrition |
