A field experiment was conducted at Quosar Orchard in Qazvin Iran during 2000-2002. Experimental treatments included three plant mulches (rye (Secale cereale L.), wheat (Triticum aestivum L.), hairy vetch (Vicia villosa Roth), glyphosate (SL 41%) applied twice, cultivation, every 4 weeks and control (weedy check). Rye had the highest dry weight. Tansy mustard (Descurainia sophia L.) in the first year and henbit (Lamium amplexicaula L.) and madwort (Asperugo procumbens L.) in the second year were the winter annual weeds. Winter weeds were controlled by rye, wheat and vetch by 81.2, 77.2, 17.3% in the first year and 96.7, 96.9 and 89.3% in the second year, respectively. Milkweed (Cynanchum acutum L.), field bindweed (Convolvulus arvensis L.) and prostrate knotweed (Polygonum aviculare L.) were the summer weeds in both years. Rye, wheat, and vetch after cutting, and glyphosate treatments controlled 45, 72, 42, and 46% of weeds in the first year and 73, 65, 58 and 81% in the second year compared to control, respectively. In the second year rye, wheat, vetch and glyphosate controlled 67, 55, 45 and 72% of milk weed, 73, 67, 60 and 85% of field bindweed and 100, 100, 100 and 56% of prostrate knotweed, respectively. Average fruit yields in both years were lowest under control treatment.
