Abstract

In order to evaluate the effect of SULPHUR fertilizer and split nitrogen application on SEED YIELD and its components of SUNFLOWER (Helianthus annuus L.), an experiment was carried out as factorial in complete randomized block design with three replicates at the research field of Birjand faculty of agriculture in 2008. The treatments were SULPHUR fertilizer in four levels (0, 200, 400 and 800 kg/ha granular organic SULPHUR) and split nitrogen application in three levels (T1:40 % at planting, 60 % at 6-8 leaves stage, T2: 40% at planting, 30% at 6-8 leaves stage, 30% at budding stage, T3: 30 % at planting, 30% 6-8 leaves stage, 20% at budding stage, 20% at flowering). Results of analysis variance showed that SULPHUR had significant effect on all traits except harvest index. Increasing levels of granular organic SULPHUR up to 400 kg/ha caused an increase in head diamater, biological yield, SEED YIELD and seed thousand weight. Hollowness percent declined with 400 kg/ha SULPHUR treatment. Split application of nitrogen had significant effect on all traits except oil percent. The highest head diamater, seed number per head, seed thousand weight, harvest index and SEED YIELD was obtained with the third treatment and the highest biological yield was obtained with the second treatment of split nitrogen application but there were no significant difference between these two treatments.
