Abstract
Using biofertilizer to reducing chemical fertilizer application and increasing yield of plant is a movement toward sustainable agriculture. Therefore to reviewing Effect of Azotobacter and Azosperillium as biofertilizer on physiological traits, yield and yield components of two safflower cultivars under different nitrogen levels, an experiment was carried out as a randomized complete block design with three replication on a farm located at 15 km of Jolfa. Test cultivars were Goldasht and Arak 2811, which stained by biofertilizer before implant. Results indicated biofertilizer factor has no significant effect on traits singly, except on biological yield and harvest index. This factor has significant effect in contrast with the nitrogen fertilizer on traits such as leaf number, secondary branch number, biological yield, petal yieldandalsoharvest index. Trait of oil percentage is significant in interaction by three factors (Nitrogen fertilizer Biological fertilizer× Cultivar). Most capital number per plant obtained by using biological fertilizer in level of 150 kg N/ha. Also most petal yield (119/2) obtained by biological fertilizer in level of 75 kg N/ha, but according to significant interaction between Nitrogen fertilizer× Biological fertilizers in petal yield, maximum amount belong to not using Biological fertilizer in absence of nitrogen fertilizer. Also, according results, grain yield has significant effect for nitrogen fertilizer and cultivars and most grain yield obtained from using 150 k/g nitrogen fertilizer per hectare. Most percentage of oil obtained by using biological fertilizer in absence of nitrogen fertilizer from Arak 2811 cultivar. On the other hand, according to superiority of Arak 2811 cultivar on trait such as leaf number, plant height, capital number, leaf area index, petal yield, biological yield, grain yield, oil percentage and oil yield seems using this cultivar is more suitable for Jolfa area.
