Agrobiological and ecological bases of productivity increase and genetic potential implementation of new buckwheat cultivars in the conditions of the Northeastern Forest-Steppe of Ukraine
In the research, agrobiological features of growth, development and productivity of different buckwheat morphotypes cultivars depending on the action and interaction of studied agronomic cultivation factors are studied. The conditions for buckwheat cultivars productivity elements formation are determined. The dynamics of plants photosynthetic surface formation of buckwheat cultivars under influence of mineral nutrition level, biopreparation, growth regulator and microfertilizer are investigated. The comparative estimation of buckwheat production modern methods efficiency is given.
Selyanochka cultivar variant with complex use of seeds treatment with biopreparation, microfertilizer and application of growth regulator in the phase of budding, on the background of mineral fertilizers use (N16P16K16+N15) formed maximum yield -2.20 t/ha, increase from fertilizers use-+0.42 t/ha, from combination ofbiopreparation, microfertilizer and growth regulator-+0.27 t/ha.
The highest yield level of Slobozhanka cultivar (1.92 t/ha) was formed in the variant mineral fertilizers’application (N30P45K45+N15) into the rows, increase was-+0.41 t/ha comparable to control. The use of growth regulator Sodium humate also provided yield increase (+0.19 t/ha).
