摘要 : The effects of planting layout (flat bed or raised bed) and weed control treatments (oxyfluorfen at 0.300 kg a.i./ha with or without hand weeding, pendimethalin at 1.00 kg a.i./ha, and 75% of pendimethalin at 1.00 kg a.i./ha + han... 展开 The effects of planting layout (flat bed or raised bed) and weed control treatments (oxyfluorfen at 0.300 kg a.i./ha with or without hand weeding, pendimethalin at 1.00 kg a.i./ha, and 75% of pendimethalin at 1.00 kg a.i./ha + hand weeding) on weed density and on groundnut yield were studied in Maharashtra, India, during 2004. The major weeds were <i>Cyperus rotundus, Cynodon dactylon, Commelina benghalensis, Parthenium hysterophorus, Tridax procumbens</i> and <i>Euphorbia geniculata</i>. Planting in raised beds recorded greater weed control efficiency (95.75%), and dry pod (12.08 quintal/ha), haulm (12.78 quintal/ha) and kernel (7.15 quintal/ha) yields. Among the weed control treatments, 75% of pendimethalin at 1.00 kg a.i./ha + hand weeding registered the greatest weed control efficiency (97.13%), and dry pod (12.95 quintal/ha), haulm (13.19 quintal/ha) and kernel (7.19 quintal/ha) yields.
