Abstract

An experiment was conducted in order to evaluate the density and dry weight of weeds and seed and oil yield of castor bean (Ricinus communis L.) as a medicinal plant that affected by cover crops, at the Agricultural Research Station, Faculty of Agriculture, Ferdowsi University of Mashhad, during growing season of 2008-2009. Treatments were included four cover crops white clover (Trifolium repens L.), fenugreek (Trigonella foenum-graecum L.), hairy vetch (Vicia villosa Roth.) and chickling pea (Lathyrus sativus L.) and control (without cover crop). Traits of study were included relative density, density and dry weight of weeds at five sampling stages and seed and oil yield of castor bean. The results showed that the lowest relative densities were observed in common knotgrass (0-1.75%), purslane and pigweed (5.88-23.80%), purslane (1.43-23.80%), redroot amaranth (5.88-27.77%) and field bind weed (5.55-26.66%) at the first to fifth sampling stages, respectively. The effect of cover crops was significant (p£0.05) on density and dry weight of weeds at the different sampling stages and seed and oil yield of castor bean. The minimum and maximum total densities of weeds were achieved in hairy vetch and control with 378.67 and 1021.39 plants. m-2, respectively. The highest seed and oil yield of castor bean were recorded in hairy vetch with 475.94 and 182.75 kg. ha-1, respectively. In overall, results showed that cover crops can be planted as an ecological approach to considered weed management and improvement quantitative and qualitative yield of medicinal plants such as castor bean.
