Abstract: A field experiment was conducted during monsoon seasons 2012 to 2014 at Junagadh (Gujarat) to study the integrated weed management in pre-monsoon groundnut. Pendimethalin and oxyfluorfen as pre-emergence, while quizalofop-ethyl, imazethapyr and oxadiargyl as post-emergence were tested alone and in integration with hand weeding and interculturing. The results revealed that pre-plant incorporation of pendimethalin 38.7 per cent CS 0.75 kg ha-1 or pre-emergence application of pendimethalin 30 per cent EC 0.9 kg ha-1 supplemented with IC and HW at 40 DAS were found equally effective to the weed free check in controlling weeds and improving growth and yield attributes and ultimately pod yield (1580 and 1538 kg ha-1) and haulm yield (2533 and 2472 kg ha-1) of groundnut. These treatments also recorded higher WCE (92.40 and 87.93%) and B:C ratio (1.87 and 1.81), therefore, these integrated weed management practices could become effective and economical under south Saurashtra agro-climatic conditions of Gujarat.
