Abstract
Weed control study on lentil was conducted during winter growing season 2008/2009 at Talkif and Namrood (Ninava Governorate) in northern Iraq to determine the effect of different tillage systems (convention, no till, no till + Gramaxon, no till + Glyphosate), seed rates (100, 120, 140 kg/ha) and irrigation systems (rainfall, supplementary) on weed growth, lentil growth and yield. The results denoted that very less number of weeds had seen at Namrood comparing with Talkif location. On other hand, unsignificant results had appeared between tillage system treatments in number, dry weight of narrow leaf weed and dry weight of broad leaf weeds only. Seed yield in no till was super passed if it compared with conventional tillage which reached up to 43.4% in talkif but that is not in line in Namrood. It is likely that the number, dry weigh of narrow or broad leaf weed were reduced significantly when lentil seed rate increased, which reflected on seed or straw lentil yield in the two locations. In general, there was superiority of supplementary irrigation on dry land farming for all characteristics in lentil. The best results in higher seed and straw yield at Talkif was with interaction of (no till x 140 kg/ha x sup. irrigation) but these trends were not cleared at Namrood especially with tillage system effect.
