The experience was conducted utilizing pots according to the completely random design method (RCBD) during the cultivation period 2022-2023 to study The influence of splatter by arginine and from condensations (0.50.100) Mg. L-1and irrigating with saltine NaCl and in condensations (0.5.10.15) ds.m-1 on some physiological adjectives of cowpea plants The outcoms indicated important increasing in the content untill vitamin C in the plant, Proline, H2O2, Salicylic acid at the treatment with the same concentration from NaCl, especially at the concentration of 15 ds.m-1 While there was important decreases in the activity of the enzyme catalase in this concentration from NaCl, when spraying the plant with the arginine lead to signification increased in the activity of the enzyme catalase and the content of vitamin C in the plant and Salicylic acid while there was a significant decreases in the Proline, H2O2 on especially at the concentration of 100 mg. L-1 of arginine even for over loop have an effect on the physiological characteristics.
