Effect of magnetically treated water and foliar nano-fertilizer on some physiological indicators in pepper (capsicum annuum L)

Abstract

This study was done on one nurseries affiliated to the center of Najaf governorate during the growing season 2021-2022 corresponding to 25/11/2021 to determination the effect of Irrigation with magnetically treated water with three intensity (0, 750, 1500) gauss and uses of Super Micro Nano-fertilizer with three levels, first level (0 g.L-1), second level (1 g.L-1) and third level (2 g.L-1). On some physiological indicators in pepper (Capsicum annuum L.). The indicators was (chlorophyll (a, b), α and β carotenes, Catalase enzyme (CAT) and Superoxide Dismutase (SOD) enzyme) in the leaves of pepper plants. The results show that the plants irrigated with intensity 1500 gauss outperformed in physiological indicators (chlorophyll b, alpha-carotene, beta-carotene, Superoxide Dismutase enzyme (SOD) and Catalase enzyme (CAT)) over the rest treatments, While the effect of interaction between the two experimental factors was shown superiority of magnetically treated water with intensity 1500 gauss and the second level (1g.L) of Nano fertilizer and third level (2g.L-1) in the content of( β-carotene, catalase enzyme, Superoxide Dismutase enzyme). While the control treatment outperformed in (chlorophyll b, α-carotene).
