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

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