Akhmed M. 3. Efficiency of measurements on Lucerne sowings protection from dodder in right-bank Forest-Steppe Zone

The object - dodder, carbamide, potassium chloride, roundup, cerb, almetide.The aim - developing the technically, economically, energetically effective and ecologically safe ways of controlling of dodder in lucerne crops.The methods - laboratory, field tests, statistic.The novelty - The reverse correlation between the period from shoots to flowering of dodder and mean daily temperature has been established. The model for prognosis of time constraints of dodder flowering has been done. Harmful capacity of dodder in lucerne has been established, yeild lossess of soilage are on the basis on 1 dodder shoot on 1 m2 - 1 centner, and on the dodder mass 1 g/m2 - 1?3 centner. New ways of killing of dodder in lucerne crops by means of phytoherbiside almetide and herbicidal composition of artificial manures.The result of research are used in education and in lucerne growing for protecting crops from dodder/Field agriculture.
