Abstract

Application of 112 to 336 kg/ha N as ammonium nitrate [NH4(NO−3)] failed to affect population numbers of common lambsquarters (Chenopodium album L.), giant foxtail (Setaria faberi Herrm.), velvetleaf (Abutilon theophrasti Medic.), jimsonweed (Datura stramonium L.), or redroot pigweed (Amaranthus retroflexus L.). Common lambsquarters seeds harvested from NO−3-treated plots were less dormant than control seeds. Seed germination in the laboratory increased from 3.0% for control seeds to 34.0% for seeds harvested from plots treated with 280 kg/ha N as NH4(NO−3). Nitrate concentration in common lambsquarters seeds increased as nitrogen fertilization increased. Seeds from nonfertilized plots contained 18.7 μg/g NO−3, while seeds from plots fertilized with 280 kg/ha N contained 126.3 μg/g. Adding exogenous NO−3 to the germination medium brought the germination of most seed lots to a similar level, except for control seeds which germinated at a lower rate. In contrast to common lambsquarters, nitrogen fertilization did not greatly affect dormancy or NO−3 accumulation in velvetleaf seeds. Exogenous NO−3 failed to stimulate velvetleaf germination because dormant velvetleaf seeds did not imbibe.
