بررسی اثر تراکم گیاهی و گونه های مختلف بر عملکرد و اجزای عملکرد ماشک علوفه ای

 To study the effects of plant density and species on forage and grain yield of Vicia sp., anexperiment was conducted in College of Agriculture, University of Lorestan, under dry farming conditions during 2007-2008 growing season. Three levels of plant density at 100, 150 and 200 seed per square meter along with three species of Vicia including Vicia narbonensis, Vicia sativa and Vicia dasycarpa were arranged factorially. The experiment was performed on the basis of a complete block design with three replications. The maximum dry forage yield of 3263 kg/ha belonging to broad leaf vetch at 150 seed/m2 was obtained. The highest stem dry weight of 1788 kg/ha was obtained from common vetch at 100 seed/m2. However, the maximum leaf dry weight of 1801 kg/ha was obtained from broad leaf vetch at 150 seed/m2. In some treatments the maximum seed yield, pod/plant, seed/pod and biological yield were obtained.
