Bioengineered ZnO nanoparticles as a nano priming agent in Cyamopsis tetragonoloba (L).Taub. to improve yield and disease resistance

Today aggressive agricultural efforts to increase crop productivity have sparked new research formulations for innovative fertilizers and natural insecticides, particularly those incorporating nanomaterials. For the first time, bioengineered ZnO NPs (nanoparticles) were done employing peel waste of vegetable extruent as a major mediator to boost the value of cluster beans (Cyamopsis tetragonoloba) seeds as well as the higher yield of cluster beans pods. The findings of several phytochemical property investigations show the creation of ZnO NPs. The agar well method was used to explore the antagonistic efficiency of plant pathogens like Staphylococcus aureus, Bacillus cereus, Pseudomonas aeruginosa, Salmonella typhimurium, Candida albicans, and Candida glabrata. For, cluster beans foliar sprays of bioengineering based ZnO nano-fertilizer at varied doses were applied. Among the various concentrations tested, the plant obtained 20 mg/L had the utmost bioactive contents in comparison to the control. Growth characters such as germination of seeds (95%), total plant length (37 cm), shoot length (20 cm), root length(8.2 cm), gross wet weight (25 gm), shoot wet weight (18 gm), root wet weight (1.92 gm), gross dry weight (6.68 gm), shoot dry weight (5.81 gm), root dry weight (0.49 gm), branch numbers (11), leaf expanse (8.9 cm), pod numbers (15), length of the pod (19.6 cm) and weight of the pod (0.126 gm) this sort of seed was recognized as being superior to hydro-primed seeds. From this investigation,we resolved that the bioengineered ZnO NPs has been effectively realized and is a biocompatible,less-toxic, ecologically friendly substance. ZnO NPs thereby synthesized proved to have exceptional antimicrobial potential against pathogens in plants as well as remarkable results in improving the growth and yield of cluster beans. Therefore, a bioengineering-based ZnO nano fertilizer can be recommended for agricultural applications.
