The article studies promising varieties of spring rape and makes an agrobiological assessment of them in conditions of summer sowing in Novgorod region on the example of the varieties Oredezh 1, Oredezh 2 and Oredezh 4. We indicate the varieties with the biggest yield of green mass and seeds, as well as having an advantage in a number of other economically valuable traits, relevant and significant for agricultural production. Features of rape in compositions with two varieties of vetch sown for green mass were studied for the first time. The most optimal composition for highest green mass yield and the best sowing season are established. The varieties of rape giving the biggest yield are identified.
