Abstract

In order to investigate the effects of NITROGEN and weeds interference (Amaranthus retroflexus L. and Chenopodium album) on millet yield and yield components, an experiment was done in a greenhouse in Bavanat region, Fars province, in atumn 2010. The experimental design was completely randomized with a factorial treatment arrangements replicated three times. The first factor, was the rate of NITROGEN from urea source including; 0, 100, 200 kg NITROGEN per ha and the second factor was the COMPETITION of millet and weeds in 3 levels including a pure millet without weeds and 2 levels of millet and weeds intercropping (pigweed and lamsquarter). Measured traits were grain yield, biological yield, harvest index and plant relative yield (PRY). The results showed that the effects of weeds interference on millet yield and yield components were significant. The increase in NITROGEN level from 100 kg/ ha to 200 kg did not noticeably affect millet yield because of the high weeds COMPETITION; the increase of NITROGEN decreased milled yield. The effect of various NITROGEN levels and various weed treatments and their effects on grain yield, biological yield and the harvest index of millet were significant. The PRY index decreased with the increase in weed density. In the mixed culture of millet and LAMBSQUARTER, PRY in LAMBSQUARTER was lower than that of millet and in the mix of millet and PIGWEED the amount of PRY was higher than that of PIGWEED. It may indicate that PIGWEED competed severely with millet.
