Abstract :

The present study deals with the impact of Zinc oxide nanoparticles on growth, biochemical characteristics and yield of Lady’s finger (Abelmoschus esculentus). Zinc oxide nanoparticles was synthesized using chemical precipitation method and characterized by using SEM, EDEX, FTIR and XRD. Pot culture studies of Lady’s Finger was carried out by using different quantities of Zinc oxide nanoparticles such as 0,100, 200, 300, 400 and 500 mg for treatment such as T₀(control) T_1,T_2,T_3,T₄and T₅respectively for a period of 60 days. Growth characteristics such as seed germination efficiency, shoot length, root length, total fresh weight, dry weight, leaf area and vigor index, biochemical characteristics such as chlorophyll a, b and total chlorophyll, carotenoids, anthocynin, protein, L–proline, free amino acids and leaf nitrate and yield parameter such as length, weight and number of Lady’s Finger per plant were estimated after 60 days. Among the treatments the shoot length, root length, dry weight were higher in T₃.The leaf area is higher in T₁and vigor index of Lady’s Finger is higher T_2.The chlorophyll a, b and total chlorophyll were higher in T3.Carotenoids,anthocyanin and free amino acids are higher in T₂ The protein content and leaf nitrate are higher is higher in T₄and L–proline is higher in T_{5 .}The length, weight and total number of Lady’s Finger are higher in T_1, T₄(22.7)and T₃respectively.
