The field experiment was carried out at Post Graduate Institute Research Farm, Mahatma Phule Krishi Vidyapeeth, Rahuri during summer 2002-03 and 2003-04 to assess the effect of pre-emergence weedicide on yield attributes and yield of groundnut in Inceptisol soil. The soil of experimental area is grouped under inceptisol soil order belonging to Sawargaon (Pather) soil series. There are fourteen treatment comprised of pre emergence weedicide application viz., oxyfluorfen, alachlor, fluchloralin and pendimethalin in graded dose, weedy check and weed control. The highest number of pegs were recorded by alachlor @ 2.0 kg a.i. ha-1 during 2002-03, 2003-04 and pooled mean. The application of pendimethalin @ 0.75, 1.50 and 3.00 kg a.i. ha-1 were recorded the less number of pods during 2002-03 and pooled mean. The higher pod yield was recorded by fluchloralin @ 0.75, 1.5 and 3.0 kg a.i. ha-1 during 2002. The application of alachlor @ 1.0, 2.0 and 4.0 kg a.i. ha-1 recorded the higher haulm yield during 2003-04, 2003-04 and pooled mean. The protein and oil content of groundnut were found the highest in weedy check treatment during 2002-03, 2003-04 and pooled mean. The higher pod yield was recorded by fluchloralin @ 0.75, 1.5 and 3.0 kg a.i. ha-1 during 2002. The application of alachlor @ 1.0, 2.0 and 4.0 kg a.i. ha-1 recorded the higher haulm yield during 2003-04, 2003-04 and pooled mean. The application of Fluchloralin as pre-emergence weedicides reported higher B:C ratio than other treatments.
