STUDIES REGARDING THE BEHAVIOR OF COMMON FLAX IN SOUTH DOBRUDJA PUBLISHEDLiliana PANAITESCU, M. LUNGU, Simona NIŢĂ, Irina MOISE
The dynamic and complex processes (exchanges of substance and energy) which occur differently for each species of cultivated plant and for each type of ecosystem are conditioned by biological requirements and by the action of vegetation factors and territorial ecological factors (climate and soil). Knowledge regarding the way in which the existing natural conditions satisfy the biological requirements of agricultural plants is of great importance for the national economy because a rational location of crops can be accomplished only starting from this scientific basis.Common flax (flaxseed or linseed) is a crop with special importance, as the seeds are used in the food and pharmaceutical industry, for the production of inks, in the soap and linoleum industry, in tannery, for the impregnation of electrical insulators etc. In the present article, the authors have tried to demonstrate that the littoral zone is suitable for the cultivation of common flax. In this regard, a flax crop was established in the didactical and experimental field of the Laboratory of Phytotechny, within “Ovidius” University of Constanta, and another crop was cultivated in the vicinity of the locality Enisala (Tulcea county).Considering that, over the recent years, common flax was cultivated in Romania on small farms (65 ha in 2005), compared to the 1980s-1990s (70-80 thousand ha), and that the average yield for our country is between 500 and 700 kg/ha (800 kg/ha at international level), but also that, in the above mentioned region, due to the fact that the surfaces cultivated with wheat, barley and sunflower increased to the detriment of other plants, a rational crop rotation can no longer be observed. Thus, this article intends to represent a starting point for the expansion of this economically valuable crop in the studied area.
