Abstract
Background and Objective: This research was designed to investigate the effect of biofertilizers, humic acid (HA) and chemical fertilizers on some growth characteristics, physiological and qualitative traits of rocket leafy vegetables.
Materials and Methods: At the University of Kurdistan, a completely randomized design was designed. Treatments included control (no use of fertilizer), AzotoBarvar-1, PotaBarvar-2, PhosphoBarvar-2, AzotoBarvar-1 + PotaBarvar-2, AzotoBarvar-1+ PhosphoBarvar-2, PotaBarvar-2 + PhosphoBarvar-2, AzotoBarvar-1+ PotaBarvar-2 + PhosphoBarvar-2, HA and chemical fertilizer. The traits that were evaluated included yield, biomass, leaf area, photosynthetic pigments, phenol, flavonoid, vitamin C, carbohydrate, nitrate, phosphorus, and potassium content.
Results: The results of ANOVA showed that the effect of all fertilizer sources on the characteristics investigated was significant. Using HA resulted in the highest yield, biomass, carotenoid, phenol, vitamin C, nitrate, and potassium content. The maximum chlorophyll a and total chlorophyll were observed using the biofertilizer AzotoBarvar-1. Maximum content of carbohydrate, chlorophyll b, flavonoid, phosphorus, and leaf area was recorded in PhosphoBarvar-2, AzotoBarvar-1 + PotaBarvar-2, AzotoBarvar-1 + PhosphoBarvar-2, PotaBarvar-2 + PhosphoBarvar-2, and chemical treatments, respectively.
Conclusion: The positive effect of biofertilizers and HA on the improvement of rocket plants growth, physiological, and qualitative traits was observed in this research. As a result, this type of fertilizers can be used as one of the most desirable methods to substitute or reduce the use of chemical inputs with the aim of improving soil fertility, producing a healthy crop and also maintaining environmental sustainability for the production of this beneficial leafy vegetable.
