Abstract
Introduction and objectives: forage production from autumn legumes is proposed as a solution to adapt to drought and climate change. This study was conducted in order to evaluate the quantitative and qualitative performance of forage of low-tannin varieties of Faba bean in autumn cultivation.
Materials and methods: This experiment was carried out as a randomized complete block design with 3 replications during 2023. In this study, 9 low tannin lines of Faba bean and two control cultivars Mehta (low tannin) and Shadan (high tannin) were compared and evaluated in two environments of drought stress and normal irrigation in terms of quantity and quality of forage.
Results: The Comparison of the average interaction effects of drought stress and variety showed that in the normal irrigation environment, the genotypes WRB1-3, FLIP03-07FB, BPL4104 and variety Shadan were the highest with 37.41, 36.67, 36.33, and 35.72 kg per hectare, respectively. More fodder yield and FLIP03-07FB genotype, Shadan variety and WRB1-3 genotype had the highest dry forage at the rate of 5.22, 5.06 and 4.92 kg per hectare, respectively
Conclusion: According to the results, it can be stated that drought stress after the flowering stage caused a decrease in the yield of fresh and dry forage and an increase in ADF, CF, and NDF values in all cultivars. BPL4104 genotype had higher performance than other genotypes in both environments, so after evaluating its performance in compatibility tests and obtaining favorable results, its cultivation can be recommended.
