Abstract
Studies were conducted to determine if 2-chloro-4,6-bls-(ethylamlno-s-triazine (simazine) or 3-(3,4-dichlorophenyl)-l,l-dimethylurea (diuron) increased the nitrate or Kjeldahl N content in the shoots or roots of wheat (Triticum aestivum L.) or soghum (Sorghum blcolor (L.) Moench)plants. Wheat and sorghum plants were grown in nutrient solutions containing several concentrations of these two herbicides for various time intervals. Nitrate N and Kjeldahl N were determined in shoots and roots and expressed as totals per plant. Simazine- and diuron-treated wheat plants had a higher nitrate N content and lower dry weight than control 6 days after treatment. The Kjeldahl N per six plants was reduced by diuron and was not affected by simazine. Diuron at 0.25 ppm was phytotoxic to wheat. An increase in nitrate was usually accompanied by a decrease in dry weight
