Abstract
A field experiment was conducted on alfisols at the Main Research Station, Hebbal, University of Agricultural Sciences, Bangalore, India, during the summer season of 1997 to study the effect of irrigation schedules and methods of herbicide application on weed characters and pod yield of groundnut. Alachlor at 2 kg ha-1 applied in irrigation water resulted in a significantly lower weed population in all areas (0.75, 1.50, 2.25 and 3.00 m). The interaction effect was significant. Scheduling irrigation at 85 mm CPE coupled with alachlor at 2 kg ha-1 applied in irrigation water gave a more efficient level of control.
