Subject(s): Summary: Maize is the most important food crop in mid hills of mid and far western Nepal. These regions fall under low rainfall zones where maize is grown under rain-fed environment. Most of the farmers in these regions do not apply chemical fertilizer for maize. Lower application of chemical fertilizer and pre- monsoon soil erosion lead to declining soil fertility. One of the potential areas in managing soil fertility decline is to identify appropriate intercropping and their combinations that fit for intercropping with maize under rain-fed bariland condition of mid hills in mid and far western Nepal. An experiment on maize-based inter-cropping was conducted at Agriculture Research Station (ARS), Dailekh during summer 2000 and 2001. Five leguminous crop viz. Soybean, black gram, groundnut, cowpea and bean were intercropped with improved and local maize varieties. Each maize variety was grown as a sole to compare between intercropping and sole-cropping. The experiment was laid out on factorial RGB-design with three replications. Grain yield of maize did not differ significantly while intercropped with different legumes. Maize variety showed a significant difference in yield when intercropped with different legumes (improved maize 4986-kg/ha and local maize 4086-kg/ha). The highest cost-benefit ratio was found with improved maize and soybean intercropping (2.24) followed by improved maize and black gram (2.11). All combinations of intercropping gave more economic return than sole maize.
