RESPONSE OF DIPLOID BUCKWHEAT OF DIFFERENT MORPHOTYPES TO HERBICIDE APPLICATION

Abstract

It was established that buckwheat competitiveness towards weeds did not depended on plant morphotype but on the special characteristics of a given cultivated variety. Herbicides used for the destruction of dicotyledonous weeds increased grain yield in diploid buckwheat indeterminate varieties in a greater extent than in determinate varieties. When on buckwheat crops graminicide Fusilade Forte was used after the preceding herbicide application for the destruction of dicotyledonous weeds, the range of the used pre-emergence products was taken into account, and on diploid buckwheat crops, the plant morphotype of the cultivated variety as well.
