Assessment Effect of Nitroxin and Phosphorus Biofertilizer on Faba Bean (Vicia faba L.) Crop Production, Seed Protein Content and Correlation between Traits

BACKGROUND: Nutrient management plays an great role for obtaining satisfactory yields and to increase crop productivity. It may be achieved by the involvement of organic sources, biologic fertilizers, and micro-nutrients. OBJECTIVES: The current study was done to investigate the effect of application of biofertilizers containing nitrogen and phosphorus biologic fertilizer on some quantitative and qualitative parameters of Faba bean and relation between measured traits. METHODS: This research was carried out via factorial experiment based on randomized complete blocks design with four replications along 2013 year. The treatments included Nitroxin biologic fertilizer (N1: nonuse of Nitroxin or control, N2: 250 cc.1000m2, N3: 500 cc.1000m2) and phosphorus biofertilizer (P1: nonuse of Phosphorus biofertilizer or control, P2: 100 gr.ha-1, P3: 150 gr.ha-1). RESULT: According result of analysis of variance effect of different level of Nitroxin and phosphorus biofertilizer on all studied traits was significant. Also interaction effect of treatments on number of seed per pod, number of pod per plant and plant height was not significant. Evaluation mean comparison result of interaction effect of treatments on all measured traits revealed the highest amount of seed yield (5096 kg.ha-1), biologic yield (9230 kg.ha-1), 1000-seed weight (1450 gr.ha-1) Seed protein percentage (24%), leaf area index (4.5) and harvest index (53.2%) were noted for N3P3 treatment and lowest amount of mentioned traits belonged to control. The most significant correlation between seed yield and Biologic yield (r=0.95**), number of pod per plant (r=0.81**), 1000-seed weight (r=- 0.73**), number of seed per pod (r=0.68**) and Harvest index (r=0.67**), respectively was observed. CONCLUSION: Finally according result of current research application 500 cc.1000m2 Nitroxin and 150 gr.ha-1 Phosphorus biofertilizer had the highest amount of studied traits and it can be advice to producers in studied region.
