The effect of growth regulator Atonic: sodium 5-nitroguaiacolate and ortho- and paranitrophenolates mixture in two concentrations - 0.1 percent and 0.2 percent, on the growth, gas exchange (CO2, H2O) and the chlorophyll content in leaves of basket willow Salix viminalis JORR form, cultivated on sandy soil substratum supplied with sewage sludge, has been examined in this experiment. Obtained results showed that applied growth stimulator, significantly increased the height, number, diameter and biomass yield of basket willow shoots. However, a significant effect on transpiration and assimilation intensity, as well as chlorophyll a + b content in leaves was observed in better condition of substratum wetting. More efficient effect was observed in application of 0.2 percent concentration of growth regulator than 0.1 percent
