The study was carried out to determine the effect of different levels of iron (0, 5, 10 and 20 kg ha(-1)) and molybdenum (0, 2, 4 and 6 g kg(-1) seed) on the yield and yield components in lentil (Lens culinaris Medic. cv. Sazak-91). The experiments were conducted in a factorial design with three replications during 2006-07 and 2008-09 in Van, Turkey. The highest seed yield was obtained from 20 kg ha(-1) iron with 956 kg ha(-1) and 6 g kg(-1) seed molybdenum levels with 963 kg he in the first year, while it was obtained from 20 kg ha(-1) iron with 1031 kg ha(-1) and 6 g kg(-1) seed molybdenum with 1010 kg ha(-1) in the second year. Seed nutrient contents such as protein rate, phosphorus, manganese, copper and molybdenum significantly increased under the influence of iron and molybdenum treatments over control.
