Abstract
Food security can be ensured by using nanotechnology to enhance crop productivity. Nanoparticles have the potential to promote the development and productivity of green vegetable plants such as fenugreek. The current study intends to examine the impact of zinc oxide nanoparticles (ZnO-NPs) on the fenugreek plant's growth and productivity, both quantitatively and qualitatively. Zinc nitrate hexahydrate [Zn (NO3). 6H2O] was chemically reduced to create ZnO-NPs. ZnO-NPs foliar application at different ratios (1:5 and 1:10 v/v) improved the fenugreek plant's growth characteristics, such as shoot length, number of leaves per plant, and dry weight of shoot and shoot dry mass. Additionally, it enhanced some biochemical characteristics, like photosynthesis pigments (chl a, chl b, and carotenoid,), that improved the produced seeds' quantity and quality, including their antioxidant activity and the proportion of protein, phenolics, and carbohydrates. The most effective treatment was 1: 10 v/v which resulted in the maximum increase within the examined parameters.
