Drozd M. Details of the buckwheat produсtivity formation depending on the technology intensification level in the northern Forest - Steppe of Ukraine

Subject of research - the process of buckwheat productivity and grain quality formation. The aim of investigations consisted in the establishment of details of growth, development and yield and produce quality formation with allowance for biological features of buckwheat plants for the varieties with various stem architectonics. The research methods are field, measuring and weight, chemical, physical, mathematical and statistical, computational and comparative. The regularities of buckwheat variety yield and nectar productivity formation with various stem architectonics depending on seed rates, fertilization and herbicide application are revealed. The buckwheat growing technology is improved what secures 2.74 - 2.83 t/ha grain of high quality and with the honey productivity 100-130 kg/ha. The worked out technologies were introduced in 2005 - 2006 at an farm of the Zhashkiv district, the Cherkasy region, over an area 50 ha. Sphere of application - the agricultural production.
