Effect of Pythium oligandrum and poly-beta-hydroxy butyric acid application on root growth, forage yield and root diseases of red clover under field conditions
Original language description
Root diseases of red clover (Trifolium pratense L.) contribute to reduced persistence and production of sown red clover stand, however, the potential of biological control of these diseases has not yet been investigated. Our objectives were to determine the effect of application of Pythium oligandrum and poly-beta-hydroxy butyric acid on (i) plant density and root morphology development, (ii) relationships between root branching and plant root disease score and (iii) forage yield and yield components of red clover in a three-year field experiment. Two red clover varieties (Start and Callisto) were established and managed under cutting (3 cuts per year) with four treatments: untreated control, spraying of poly-beta-hydroxy butyric acid (Albit), or application of P. oligandrum (Polyversum) at two intensities. Each autumn, plants were evaluated for root morphology traits and scored for root diseases. Forage dry matter yield, compressed stand height and stem density were evaluated in each cut. Effects on
