Abstract

Moringa leaf extract (MLE) as a biostimulant has demonstrated success in boosting the productivity of several agronomic crops, but its impact on Buckwheat crops remains unexplored. Buckwheat, recognized as an essential nutritional and functional food crop, often exhibits lower yields compared to major cereal crops grown in similar environments. Therefore, this research aimed to investigate the impact of different concentrations (1%, 2%, and 3%) of MLE on the agricultural performance of common buckwheat (CB) and tartary buckwheat (TB). A pot experiment was carried out according to completely randomized design with factorial arrangements having three replications. Results demonstrated significant improvements in growth parameters (branches, leaves, nodes, and internodes) for MLE-treated plants compared to the control group. Foliar treatment MLE 2% also increased chlorophyll content, improved membrane stability index (MSI) and relative water content (RWC), and enhanced biochemical composition (phenolic compounds, free amino acids, leaf proline, and soluble sugars) in both buckwheat genotypes followed by MLE 3% and MLE 1%. TB produced significantly higher grain yield (0.74 g) as compared to CB (0.43 g). The findings showed that a foliar treatment of MLE 2% led to increased grain yield in both TB (0.97 g) and CB (0.55 g) as compared to control group plants (0.37g TB and 0.22 g CB) respectively. This increase was associated with elevated activities of photosynthetic pigments, phenolic content, RWC, free amino acids, soluble sugars, and catalase in both buckwheat genotypes. In conclusion, MLE application at 2% significantly boosted the agriculture performance of buckwheat, and this study unlocked new insights into optimizing the productivity of the vital food crop.
