TRITICALE PRODUCTIVITY UNDER EXTREME FROST DEPENDING ON VARIETY AND NITROGEN NORM PUBLISHEDH. Kirchev, T. K. Tonev, Zhivko Terziev, Nadezhda Semkova None
The following evidence are based on field experiment carried out in a sample area of Dobroudja Agricultural Institute. In this experiment took place 5 triticale varieties which have been made in different selection research stations. It has been established that triticale is high sensitive plant to low temperature in the winter time in this region. It could be placed between wheat and barley in a scale of such sensitivity. As a most resistant to low temperature among the explored species were established Sadovec and Rakita. Nitrogen fertilization cannot compensate the thinning out of the crops. It even can result in secondary infestation and some additional problems for harvest.
