Field experiments were conducted at Agricultural College and Research Institute, Tamil Nadu Agricultural University, Coimbatore to study the efficacy of different methods of weed management systems namely manual, chemical and biological in Pigeonpea during kharif and rabi 1983–84. The treatments consisted of three chemicals (fluchloralin, pendimethalin and oxadiozon alone and supplemented with one hand hoeing, manual (two hoeings at 20 & 40 DAS and two intercropping systems (Pigeonpea + sorghum and pigeonpea + moong and intercropping combined with one initial hoeing) along with unweeded check, accounting twelve treatments replicated four times in randomized block design. The results revealed that application of pendimethalin 0.50 kg ai ha −1 supplemented with hand hoeing 40 DAS is found to be effective in controlling the weeds in sole pigeonpea under irrigated conditions.
