Abstract :

In or order to determine optimum seed density and sowing time of lentil (lens culinaris medic.) in khoramabad city, this study was conducted in 2008-2009 growing seasons. There were five seed density levels 200, 250, 300, 350 and 400 seed/m 2 , and two sowing seasons: Autumn and spring seasons traits such as grain yield, biological yield, pod and grain numbers per square meter, single seed per square meter; double seed per square meter were recorded. After harvesting, 100 grain-weight, grain yield and biological yield were measured and recorded. Analysis of variance showed that the effect of sowing dates on grain yield, biological yield, pod and grain numbers per square meter, single seed per square meter; double seed per square meter, were significant. Autumn sowing date significantly increased grain and biological yield, harvest index, pod and grain numbers per square meter. Different plant density effects were also significant on grain yield The highest grain yield belonged to 350 seed per m2 (1600 kg/ha-1) and autumn sowing time. (1575 kg/ha-1). These results recommend that in dry land conditions of lorestan lentil are to be grown as autumn crop with 300 seed per m2.
