Abstract:

 In this study, the effects of different doses of organic OF, vermicompost VC, and chemical CF fertilizers on phenological characteristics, polyphenolic compounds, and antioxidant capacity of Amaranthus caudatus L. were evaluated. The study was carried out using a randomized block design with four replications. The findings revealed that the fastest germination occurred in the CF-6 Lda group, with a mean time of 7 days, while the slowest germination was observed in the OF-1200 mLda group, with a mean time of 16 days. Regarding flowering time, the earliest flowering occurred on the 68th day in the CF-3 Lda group, while the latest flowering occurred on the 79th day in the OF-1200 mLda group. The longest vegetative period was observed in the OF-1200 mLda group with 215 days due to the effect of fertilizer applications and the fact that the study was carried out in the summer season. The closest vegetative period to the control group was 187-190 days in the CF-6 Lda group. The treatment groups total phenolic content TPC and total flavonoid content TFC exhibited a range of 0.29-2.46 mg GAEg and 0.50-1.26 mg QEg, respectively. The highest TPC and TFC values among the treatment groups were determined in the OF-300 mLha and VC-2 Lha groups, respectively. The IC50 values of 2,2-Diphenyl-1-picrylhydrazyl DPPH radical scavenging activity of methanol extracts exhibited a range of 3.34 to 6.80 mgmL, with the OF-300 mLda 50 mgmL group demonstrating the highest radical scavenging activity, exhibiting an 89.95 inhibition rate.
