RESEARCHES ON THE MAIN FIELD CROPS YIELDS VARIATION IN THE BURNAS PLAIN BETWEEN THE DRY YEARS 2000 AND 2012

In this paper an objective synthesis is made on the productions obtained from wheat, barley, maize, sunflower and rapeseed crops in a quite long period of time, during which at least 4 years may be considered as being dry and extremely dry (2000, 2003, 2007 and 2012). To achieve the established objective we chose Burnas Plain as case study, part of the Romanian Plain, well known for its agricultural importance in Romania. Also, within this subdivision we will make a brief analysis of the meteorological phenomena produced on the territory of Teleorman County, the place where we conducted our field researches and for which we collected information regarding the evolution of temperatures and precipitations. Based on all these results we have calculated the impact of thermo-hydric stress on the agriculture in the territory. The data used for maps, tables and graphs creation were taken from the Statistical Yearbooks of the National Institute of Statistics and from the National Institute of Meteorology and Hydrology database, while those for 2012, which weren’t centralized and disclosed yet, are obtained from our own experimental fields and from others big agricultural producers in the area. In this way we will be able to emphasize the important role of climatic conditions for agricultural yield in the south part of Romania, currently with poor irrigation possibilities, and the necessity of finding solutions to this problem through research.
