The article studied the influence of the micromycete TR. Asperellum and molybdenum on nitrate reductase activity and morphological parameters of the root and aerial part of 3 weeks old cowpea plant of the Galib variety (Vignaunguiculata (L) Walp) under chloride salinity (50,100 ,150 mMNaCL). It is shown that the reason for the decrease in plant weight in a saline environment is partly due to the weakening of nitrate nutrition. Trichoderma and molybdenum protect the enzyme from the toxic effect of chloride salinity, positively affecting the activity of plant nitrate reductase in a salty environment. It is believed that TR Asperellum, like molybdenum can play an important role in plant productivity.
