Abstract :
This experiment was conducted based on factorial layout with completely randomized block design with 3 replications. The first factor was humic acid fertilizer in three levels (0, 50 and 100 mg/L) and the second factor was salicylic acid at 3 levels (0, 2 and 4 mM). The results showed difference between the levels of Humic iron fertilizer in terms of number of seeds per pod 1000 seed weight, grain yield, biological yield and harvest index at 1% level of probability. The difference between salicylic acid levels was significant in all traits measured at 1% level. In interaction, number of pods per plant and grain yield were significant at 5% probability level, but no significant difference was observed in the remaining traits. The highest grain yield in the interactions of humic acid and salicylic acid was observed in treatment of 100 mg/l humic acid and 4 mM salicylic acid with 2793 kg/ha and the lowest in control treatment with 1033 kg/ha. The highest number of pods per plant was related to treatment with 100 mg / l humic acid and 4 mM salicylic acid with 25 pods per plant and the lowest in control treatment with 15 pods per plant. According to these results, application of concentration of 100 mg/l of humic acid and 4 mM salicylic acid in comparison to other treatments improves the growth analysis and increases the yield and components and is recommended in the region as well.
