Simazine applied at three rates 2.5, 5, and10 lb. active ingredient per acre showed a decrease in yield of maize plant compared with control irrespective of maize variety. Result indicated that some varieties might be more affected than others. It is suggested that these varietal differences might be due to planting depths or to various degrees of root mass development of the varieties. Root development of maize was restricted in the simazine-soil layer, and the ratio of top to roots increased with increasing rate of simazine application. Percentage of nitrogen in simazine-treated plant material increased with increasing rate of herbicide application but total nitrogen uptake decreased as result of decrease in plant yield. Percentage of phosphorus as well as total phosphorus absorbed increased with increasing rate of simazine application, while per cent K was largely unaffected.
