The Venezuela areas with soils classified as Inceptisols, Vertisols and Alfisols, present in Barinas and Portuguesa States, are most suitable for sunflower crop. Soil pH is more than 5.8, with moderate to high moisture retention, and textures varying from loam, sandy loam to clay loam. The climate is tropical with a 12-12.5 h day/dark photoperiod. The average experimental yield is 1,500 kg ha"1. Sunflower is sown after a main crop (corn, rice) usually in October-November in high areas, and November and December in low areas. Harvest occurs at the beginning of year, in the absence of rainfall. The main problems are: selection and soil preparation, planting dates, hybrids not adapted to tropical conditions, and the high price of seed, which is imported.
