Abstract

In order to study of defoliation based on leaf position and NITROGEN effect on seed yield, yield components and germinationtraits of produced seeds in maize, a field and a laboratory experiments were conducted in Kermanshah in 2013. At the fieldexperiment, studied factors included defoliation based on leaf position (no leaf removal, removal of leaves at the top of ear, removal of leaves under the ear and all leaves removal) and NITROGEN rates (0 and 100 kg ha-1). Produced seeds from the fieldexperiment were used at the laboratory experiment to determine MATERNAL PLANT environment effect (field treatments) on seedgermination traits. Results showed that complete defoliation at tasseling stage, had no seed number per column, seed numberper row of ear and seed yield. Under no leaf removal, NITROGEN application reduced seed yield. Removal of leaves at the top andunder the ear and NITROGEN had no significant effect on germination percentage, caulicle and radicle length and seedling weightof produced seeds. Under NITROGEN application, removal of LEAVES AT THE TOP OF THE EAR reduced SEED VIGOR based on weight. Itis recommended that if NITROGEN is applied at tasseling stage, it can be possible to harvest leaves under the ear to feed animalswithout maize seed yield reduction
