Abstract

Nanoparticles have become integral in various aspects of agricultural practices, including the development of nano-fertilizers for optimized crop nutrition. This study aimed to explore the effects of foliar application of Allium sativum mediated SeNPs at various doses including (15, 30, 45, and 60 mg/L) on plant growth. The focus is on assessing their impact on germination, morpho-physiological, biochemical, and antioxidant profile of three Capsicum annuum varieties (Megma-F1, Sky-7, and AS-8282). The SeNPs were characterized through ultraviolet-visible spectroscopy, fourier transform infrared, and scanning electron microscopy. Different plant growth physiological, biochemical, and antioxidant traits were analyzed. The results indicate that the highest germination rate was 80% for Megma-F1, with an 84% rise in SVI reported in Sky-7 at 60 mg/L. Megma-F1 and Sky-7 showed one-fold increases in chl a content, while AS-8282 had a three-fold increase in chl b level. The highest TFC and TPC contents were 38.25 mg/g and 26.2 mg/g for Megma-F1 and AS-8282, respectively, while marginal variations were found for SSC and TPC. The highest DPPH radical scavenging activity recorded was 74% and ABTS with 76% for AS-8282 at 60 mg/L. It was concluded that both treatments have a positive impact on plant growth. The research contributes to evolving the field of agri-nanotechnology emphasizing the importance of nanoparticle concentration positively influencing plant performance, paving the way for sustainable agricultural practices.
