An axparimant was conducted under irrigated conditions to evaluate the effect of three herbicides viz.. alachlor. nitrofen and penoxalin en weed growth and growth and yield components and pod yield of POL 2, a bunch groundnut cultivar, None of the herbicides proved superior to hand weeding in suppressing weed growth. While growth components like number of branches, rest weight, and nudulation were unaffected. dry mattar production registered an increase following herbicide application, Kernel weight or shelling percentego was not yuverned by herbicide but pod number increased under alechtor and nitrofen and decreased under penoxalin. Ped yield under the herbicides was comparable with that under hand-weeding. But from the standpoint of monetary returns. elechlor had a clear edge over either of the other two herbicides. or hand weeding and may therefore be safely recommended.
