Experiment on effects of vanadium on the rice growth in hydroponic culture with the Mckeehen's nutrient solution formulae had been conducted from September 5 to January 3, 2005 at Department of Agricultural Technology, Thammasat University, Rangsit Campus, Thailand. Vanadium at 80 mg/L caused the lowest stem height, stem diameter, fresh and dried stem weights, and fresh and dried root weights of 84.21 cm., 1.98 cm., 24.44 and 9.61 g, and 20.59 and 1.47 g, respectively. Vanadium concentration at 0 mg/L had a tendency to give the highest root length of 48.85 cm, the highest number of panicles per hill of 11.00, the highest number of seeds per panicle of 222.18, the highest weight of seeds per hill of 58.55 g, and the highest 100-seed weight of 2.40 g. The two vanadium concentrations at 40 and 80 mg/L, however, caused death to the rice plant before the flowering stage. The orderly concentrations of vanadium from high to low were found in the rice root, leafy stem and seed, respectively.
