Abstract :

This study set out to investigate the effect of bio-fertilizers containing nitrogen-fixing bacteria and phosphorus on grain yield and yield components of Faba bean. To this end a factorial experiment on the basis of randomized complete block design with four replications was conducted in Behbahan region at South eastern part of Khuzestan Province of Iran. The experimental treatments included Nitroxin containing nitrogen-fixing bacteria in three levels of 0, 250, and 500 cc per 1000 m2 and phosphorus bio-fertilizer (fertile 2 phosphates) containing phosphorus-fixing bacteria in three levels of 0, 100, and 150 g.ha-1. The results showed that the effect of treatments with phosphorus bio-fertilizer and Nitroxin on grain yield, biological yield, and harvest index, number of pods per plant, number of grain per pod, 1000-grain weight, and leaf area index was significant at 1% level. The highest grain yield, biological yield, harvest index, number of pods per plant, number of grains per pod, 1000-grain weight, and leaf area index belonged to the treatment with consumption of 500 cc Nitroxin per 1000 m2 and 150 g.ha-1 phosphorus bio-fertilizer and the lowest rates belonged to the control treatment.
