RESEARCH ON THE INFLUENCE OF POST-EMERGENT HERBICIDES APPLIED AT DIFFERENT STAGES ON OLT AND GENEROS CORN HYBRIDS UNDER THE CONDITIONS OF MOARA DOMNEASCA

The paper presents the results obtained at the Didactic Farm Moara Domneasca - Ilfov County, on a reddish preluvosoil on Olt and Generos corn hybrids, during the period 2011-2013, following the application of herbicides at several stages. The results obtained bring an important contribution in clarifying the best period for the application of herbicides on corn hybrids, the factor which must be taken into account in establishing the best moment to apply herbicides: the hybrid’s precocity, its development phenophase, the weed development phase, the evolution of the climatic conditions or all these aspects in their integrality.
