Determination of chlorophyll content, carbonic anhydrase activity, bio-productivity and composition of groundnuts under five Zinc Oxide (ZnO) applications

The low level of carbonic anhydrase activity in groundnut grown on soil with limited zinc (Zn) content is one the factors responsible for yield groundnuts Nigeria. Hence, this study was carried out to further strengthen significance Zn enhancing photosynthetic processes through activity. It also determines how application affects biochemical components, growth, and composition Arachis hypogaea cv SAMNUT 22. In study, a potexperiment performed investigate effects five concentrations applied form oxide (0.00, 1.00, 2.00, 3.00 4.00 gL-1ZnO) chlorophyll, activity, bio-productivity proximate seeds. Data aforementioned parameters were subjected One-way Analysis Variance means separated using Duncan Multiple Range Test at p<0.05. results showed that total chlorophyll leaves increased increasing concentration ZnO hence lowest highest recorded 1.00 gL-1 respectively. Carbonic anhydrase, after flowering marked improvement increases compared control. terms growth components attributes respectively enhanced when increased. Carbohydrate, protein ash harvested seeds significantly higher (p<0.05) treated plants indicated considered optimum enhancement biochemical, studied groundnut. Also, reported positive influences only carbohydrate, contents
