Yield Response and Competition Ability of Italian Ryegrass, Red Clover and Their Mixture to Different Technological Conditions�

Abstract

The effect of different technological conditions on forage yield, growth behavior and competition ability of ryegrass, red clover and their mixture was analyzed. The results showed that red clover makes better use of the nutrition space in the case of variants sown in mixture with Italian ryegrass than in the monoculture, independent of the density of the plants or fertilization regime. The highest DM production was obtained at the mixture formed by red clover and Italian ryegrass on the variants sown on 12.5 cm distance between rows, the increase of the nutrition space being directly proportional to the decrease of the DM production in the case of this forage mixture.
