The effect of Azofert® on bean plants on the relative water content and the pigments concentration under two irrigation regimes was evaluated. The experiment was carried out in the light room of the Department of Plant Physiology and Biochemistry of the National Institute of Agricultural Sciences, San José de las Lajas, Mayabeque. The varieties CC-25-9R and Tomeguín-93 were used. In each case, Azofert® was applied, with a dose of 200 mL per 50 kg of seed at the time of sowing and as controls were used treatments without the application of this product. The irrigation treatments consisted of applying 100 and 50 % of the maximum moisture retention capacity. A completely randomized design was used. Ten plants were selected at random for each treatment to evaluate fresh leaf mass, saturated mass, fresh leaf mass, relative water content and concentration of photosynthetic pigments. The results showed that the bean plants are affected when subjected to a soil moisture deficit and also that the inoculation with Azofert® was able to attenuate the effects of water deficiency. The relative water content decreased significantly in both varieties when humidity is reduced. The chlorophyll b content was affected in both varieties when subjected to water stress conditions. The content of carotenoids in the CC-25-9R variety had a significant increase in water stress conditions..
