THE BEHAVIOUR OF CERTAIN SUNFLOWER HYBRIDS IN THE PRODUCTION CONDITIONS OF DOBROGEA PUBLISHED

Liliana Panaitescu
During the latest years, farmers have had to deal with a problem in Dobrogea: the presence of broomrape in the sunflower fields. The main causes of this phenomenon are the fact that rotation is not observed and the use of hybrids that do not resist to the attack of this parasite. Every year, specialists warn about the appearance of new broomrape varieties that are more and more resistant. The efficient pest control measures used previously prove to be useless against the most recent varieties. The paper observes the production behaviour of several sunflower hybrids recommended to be cultivated in Dobrogea, considering both the resistance to broom rape attack and a few productivity elements.
