RESEARCH ON THE BEHAVIOR OF SOME SUNFLOWER GENOTYPES IN THE CONDITIONS OF SANDY SOILS IN THE SOUTH-WEST OF OLTENIA

Abstract

The sunflower is a plant well adapted to the pedo-climatic conditions from Romania, having a high productive potential. There are several varieties and hybrids of sunflowers, each of which has its own requirements for cultivation and also, maximum production potential utterance. Till now, the climatic conditions recorded in the area of sandy soils in the South of Oltenia were favorable for the growth and development of sunflower plants. In 2022 year, the studies on the behaviour of 24 sunflower genotypes in the conditions of sandy soils in Southern Oltenia was carried out at the Research Station Development for Plant Culture on Sands Dăbuleni. Here, the yield recorded for the 24 genotypes of sunflower evaluated, showed productions between 2743-3188 kg/ha, with an average of 2989 kg/ha, compared to which they were highlighted by production differences of 156-199 kg/ha, statistically assured as significant and distinctly significant, genotypes: T 19 - 9A1, T 19 - SU- 6A and ANT -IMI- CL+/2066A.
