Abstract

In the paper are presented results of seed treatment investigation of sunflower, regarding a time from seed harvesting to cleaning and drying, and chemical seed treatments. Each treatment is examined in laboratory (seed vigor and germination) and field (field emergence and grain yield). Statistically significant (P=0,05), the highest seed vigor (91,4%) and laboratory germination (94,2%) had sample U1 (in shortest time cleaned and dried). From chemical treatments, statistically significant (P=0,05), the highest seed vigor (91,3%) as well as laboratory germination (93,5%) had combination Apron XL 350 ES, KSj (metalaxyl 35%) + Vitavax 200 FF, SC (carboxin 20% + thiram 20%), in dose 300+250 ml/100 kg of seed (chemical treatment - T2). For field emergence and grain yield have not found statistically significant differences neither between samples nor between chemical treatments.
