摘要：
An experiment was conducted during rainy (kharif) season of 1997 and 1998 to study the different weed-management practices on groundnut (Arachis hypogaea L.). Pre-emergent application of Alachlor @ 2 kg ai/ha or Fluchloralin @ 1.0 kg ai/ha or Pendimethalin @ 1.0 kg ai/ha, followed by post-emergent application of Fluchloralin @ 1.0 kg ai/ha I day after interculture at 20 days after sowing increased pod yield 94.1, 89.3 and 88.0% respectively over the unweeded control (810 kg /ha). The respective net monetary returns were Rs 7 916, Rs 8 528 and Rs 8 341 ha compared with Rs 770 with unweeded control and Rs 5 467 with farmers' practice of hoeing and weeding at 20 days after sowing, Integrated weed management involving pre-emergent application of Alachlor @ 2 kg ai/ha at I day after sowing, followed by post-emergent application of Fluchloralin @ I kg ai/ha at I day after interculture recorded higher weed control efficiency (87.9%).
