Abstract: Nitrobenze is oily colorless liquid with flavor of bitter, which is denser than water. Nitrobenze ,which is poisonous, is important material to manufacture dyestuff. There were less research of nitrbenze on growth of crop. Take rice line Ha04-34 as material, effect of contamination of nitrobenze on rice growth, yield traits and food security were studied. The results were as follows: effect of nitrobenze on rice growth were delaying heading and maturity, and reducing spikes per hill. The paddy, when concentration of nitrobenze was above 3 times of state standard in irrigating water, could not cultivated rice, and it had not detected nitrobenze residue in seed only the rice could to maturity.
