Abstract

The effect of cadmium (Cd) of atmospheric origin was investigated on certain terms in the heat balance and on the dry matter production of maize grown in the field at two water supply levels (rainfed and irrigated) in Hungary between 2010 and 2012. In contrast to previous experiments, the plants were exposed to pollution every week throughout the vegetation period. Among the plant parameters, a record was made of plant height, leaf area index and the length of the growing period. Water utilisation was estimated on the basis of water use efficiency, and efficiency from global radiation. Polluted maize used more water for the incorporation of unit dry matter, and was unable to absorb as much solar radiation as the unpolluted control plants. Irrigation moderated the negative effect of Cd on these parameters, suggesting that it could be of primary importance in overcoming the effects of Cd pollution of atmospheric origin.
