A field experiment was conducted at Quosar Orchard in Qazvin during 1998-2000. Plant mulches rye (Secale cereale L.), wheat (Triticum aestivum L.), and hairy vetch ( Vicia villosa Roth.), glyphosate (SL 41 %), cultivation and control were the expriment treatments. Rye had the highest leaf area index and 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. Milk weed (Cynanchum acutum L.), field bindweed (Convolvulus arvensis L.) and prostate knotweed (Polygonum aviculare L.) were summer weeds in both years. Rye, wheat, and vetch after cutting, and glyphosate controlled 48, 74, 51.5, 50.5% 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 prostate knotweed, respectively. Control had the lowest yield.
