Özet
This study evaluated the suppressive effect of several important summer crops on purple nutsedge (Cyperus rotundus L.) growth and reproduction for two growing seasons under greenhouse conditions. Mungbean [Vigna radiate (L.) Wilczek], cotton (Gossypium hirsutum L.), millet [Pennisetum glaucum (L.) R. Br.], sesame (Sesamum indicum L.), sorghum [Sorghum bicolor (L.) Moench], cowpea (Vigna unguiculata (L.) Walp.) and groundnut (Arachis hypogaea L.) were grown in monocultures and with ten sprouted C. rotundus tubers transplanted at 14 days after sowing of crop. At 75 days, different crops in the study reduced the growth of C. rotundus by 1-88%. However, the weight per tuber increased in the crop-weed mixture treatments relative to C. rotundus grown alone. Sesame was the most effective crop in suppressing C. rotundus in terms of different growth parameters (25-88%), followed by cowpea (14-85%) and millet (26-74%). Cotton and groundnut were found least suppressive to C. rotundus. Reduction in crop growth due to C. rotundus interference ranged from 2-46% and was more pronounced in root growth (4-46%) than the other crop growth and yield parameters. The adverse effect of C. rotundus was greater for millet, green gram and cowpea than for cotton and sesame. Our findings suggest that sesame can effectively suppress C. rotundus, and different cultivars of sesame may be evaluated under field conditions for their weed suppressing ability.
