This comparative experiment was undertaken to study the effect of action and interaction of three variants of nitrogen levels and three seeding densities on three Bulgarian cultivars: Viktoria, Beloslava, Deana and the French Pescadou under the agroecological conditions of South Bulgaria. It was established that the grain yield mainly depended on the nitrogen fertilization.
This study confirmed that the events of the Bulgarian varieties were more related to the structural elements of the grain yield: number and weight of grains in the spike, while the French variety Pescadou produced a high yield as a result of determining more productive spikes per m2.
