ABSTRACT
A field study pertaining to different intertillage practices on maize was conducted in spring 1998. Different intertillage practices comprised of no intertillage + no earthing-up, no intertillage + earthing-up, intertillage twice with Tarphali + no earthing up, intertillage twice with Tarphali + earthing-up, manual weeding + no earthing up, intertillage twice with spade + earthing-up. The significant maximum grain yield (4.3 t ha-1) of maize and net income (Rs. 27713) was obtained by intertillage twice with spade and earthing-up as against the minimum grain yield (3.02 t ha-1) with net income of Rs. 20385/- ha-1 in case of no intertillage + no earthing up treatment.
