Abstract
In field, soil culture, and nutrient culture experiments, 2-chloro-4-ethylamino-6-isopropylamino-s-triazine (atrazine) increased percent total nitrogen in all species studied, whether resistant, intermediate, or susceptible to 1 lb/A of atrazine. However, nitrogen content per plant was either unaffected or decreased by these atrazine treatments. One lb/A of atrazine increased percent protein and nitrate nitrogen in most species studied. Atrazine susceptibility apparently was related to its effect on percent non-protein and ammonia in the species tested. One lb/A of atrazine had no effect on percent non-protein nitrogen and decreased percent ammonia nitrogen in resistant species but increased both fractions in intermediate and susceptible species. One lb/A of 2-hydroxy-4-ethylamino-6-isopropylamino-s-triazine (hereafter referred to as hydroxyatrazine), a degradation product of atrazine, had no consistent effect on any nitrogen fraction studied.
