| Sumario: | Background and Objective: This study was conducted to investigate the effect of biofertilizer application and drought stress on yield and yield components of pea (Pisum sativum L.) seeds. Materials and Methods: The experiment was carried out in the lands of Gomand village of Khajeh section of Harris city of East Azerbaijan province, located 15 km east of Tabriz, in a factorial manner in the main design of random complete blocks.Experimental factors were included irrigation in four levels (normal irrigation as control, water shortage at grain filling stage, water shortage at flowering stage and without irrigation) and biofertilizer at eight levels (no inoculation as control, inoculation with Azotobacter, Azosprilium, Mycorrhiza, both application of Azotobacter and Azosprilium, Azotobacter and Mycorrhiza, Azosprilium and Mycorrhiza, Azotobacter and Azosprilium and Mycorrhiza). Results: The 100 grain weight, plant height seed per pod, pods per plant, protein percent, harvest index, pod length were significantly affected by different irrigations and biofertilizers treatments. The water stress caused to reduce of yield and yield components. The water stress caused to reduce of plant height seed per pod, pods plant, protein percent, harvest index, pod length and increased 100 grain weight. The application individually and combination of biofertilizer caused to increase of 100 grain weight, plant height seed per pod, pods plant, protein percent, harvest index, pod length. Conclusion: The results of this study showed that the highest level yield was achieved by applications of Azotobacter, Azosprilium and Mycorrhiza at planting in the complete irrigation conditions. |
