Abstract

The experimental field was placed in Amzacea, Constanta County at S.C. SPORT AGRA S.R.L., Center of Development, on the highway 38, 20 km. far from Bulgarian border. Constanta County had the largest weight regarding the surface cultivated in Romania with sunflower crop between 10-12%. The most drought area in Romania is Dobrogea (average 1961-1990: 464 mm rainfall). Climatic change in recent years has accentuated this tendency. The number of hybrids taken into account in our experiment were fifteen in 2018 and twenty in 2020. Genesis has been planted in two periods of the time in 2020. When the planting was delayed the yield was decreased by 303 kg/ha. The aim of this study was: (i) the behaviour of the hybrids in the unbeliveble dry conditions, (ii) to see the yield and the behaviour of sunflower hybrids to the attack of main pathogens - Sclerotinia sclerotiorum, Phomposis helianthi, Orobanche cumana, (iii) how the planting date influenced the yield, (iv) the importance of the pesticides used and (v)economical data.
