Abstract

In order to study the effects of BIOFERTILIZERS on SEED YIELD and yield components of three sunflower cultivars a two-year research was carried out at Agricultural Research Station of Khoy during 2007-2008. A factorial experiment based on randomized complete block design with four replications was used. The cultivars of sunflower, as the first factor, were Hisun33, Alstar and Euroflor; and the second factor consisted of different combinations of biofertilizer inoculants and chemical fertilizers (50% K2SO4+biosulfur, 100% K2SO4+biosulfur, 100% K2SO4, 50% urea+azotobacter, 50% urea+nitroxin, 50% urea+azotobacter+nitroxin, 100% urea, 100% urea+100% K2SO4 ) in 8 levels. The results of the experiment showed that effects of cultivar and fertilizer on number of seed per head, 1000 seed weight, seed and oil yields were significant. The interaction effect also was significant on harvest index and oil yield. Mean comparison among cultivars showed that Hisun 33, produced higher yield and yield components (707 seed per head and 1000 seed weight of 56.7 grams, SEED YIELD of 3832 and oil yield of 1705 kg per hectare respectively) than the other two cultivars. Among the different levels of fertilizers biosulfur+100% K2SO4 and 50 % urea+azotobacter+nitroxin had the highest positive effect on seed and oil yields increase. It can be concluded that use of biofertilizer reduces chemical fertilizer applications and improves both quantity and quality of oil in these cultivars.
