UllahEhsan 9200039A 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 ha1) 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 ha1) with net income of Rs. 20385/ha in case of no intertillage + no earthing up treatment.]]>Adil, M., M.
