Abstract

In order to evaluate the effect of different nutritional treatments on forage yield and some qualitative traits of artichoke (Cynara scolymus L.), an experiment was conducted as factorial experiment on the basis of RCBD design with three replications in Isfahan Agriculture and Natural Resources Research Station, Iran during 2014. The first factor consisted of chemical fertilizers at levels of 100% chemical fertilizer (200-100 kgha-1 NP), 50% chemical fertilizer (100-50 kg ha-1 NP), and control. The second factor comprised biofertilizer at levels of 1 liter ha-1 Nitroxin (include Azotobacter, Azospirillium and Pseudomonas), 100 gha-1 Barvar 2 (include Pseudomonas potida and Bacillus lenthus), 1 liter ha-1 Nitroxin +100 gha-1 Barvar 2 and control. The results showed that soil fertilization treatments significantly affected forage quantity and qualitative traits of artichoke. The effects of chemical fertilizers on the majority of traits in artichoke were statically significant, however, t

Conclusion

In this research soil fertilization had a significant effect on forage yield and quality of artichoke. Obtained findings indicated that the soil on the experimental site was poor and all the fertilization treatments significantly increased forage quality parameters compared to control. The effect of biofertilizers on the majority of traits in artichoke were significant.

The highest amount of dry forage yield (12.1 t ha-1), crude protein (19.53%), p content (622.2 mg/kg) and organic matter digestibility (86.56%) obtained in integrated application of biofertilizers and chemical fertilizers, particularly, inoculation with Nitroxin + Barvar 2+100 % chemical fertilizers. This study showed synergistic effects of combined inoculation of PGPRs. Totally
