Silicon (Si) has beneficial effects on the growth, yield, and tolerance of some crops against biotic and abiotic stresses. Considering the absence of Si in the nutrient solutions used in hydroponically-grown cucumber, the present study was conducted to investigate the influence of Si on the growth and yield of two cucumber genotypes (Cucumis sativus L. cvs. Dominus GRC and Super Dominus). In a hydroponic experiment, two cucumber cultivars were exposed to three Si levels (0, 100, and 200 mg L-1 Si in the form of sodium silicate). The results showed that supplement of Si in the nutrient solution increased Si concentration in cucumber root and shoot. The root and shoot dry weight, crop height, and root length of cucumber plants were significantly (P< 0.05) greater in the presence of Si in comparison with the free- Si treatments. Most of the growth parameters, did not have significant difference at the 100 and 200 mg L-1 silicate levels. According to the results of the present study, it seems that the application of 100 mg/L Si in the nutrient solution could improve the growth and yield of cucumber.
