To study various forms of tillage and residue management, and the timing of such operations for lentil (Lens culinaris, L) agriculture after wheat (Triticum turgidum sp. durum) harvest in rainfed areas of South-East Anatolia Region of Turkey, ten different treatments were evaluated for three years from 2002 to 2005. According to statically analysis results of data obtained from experiment, the effect of treatments on weed density was significant. Secondary tillage after rainfall reduced both grassy and broad leaf weed density. The residue burning didn't significantly reduce weed density. Late plantings gave significantly higher lentil seed yield than early plantings. The T9 treatment which was residue chopping + summer chisel + cultivator after rainfall + late planting gave the highest grain yield and net benefit. The other treatments were dominated due to less net benefit and higher costs that vary. Therefore, they were considered as uneconomical treatments.
