This investigation was carried out to identify appropriate combination or plant population of maize and cauliflower for intercropping in potato + maize cropping system. The experiment was carried out at Sinduwa Sub-station, Dhankuta during 1998 to 2000. Three spacings for both of the crops were tested and cauliflower was transplanted after the harvest of potato. Maize grain yield was significantly (P < 0.001) higher (2.66 t/ha) in closer (100- x 25-cm) spacing. Similarly, closer spacing (45- x 30-cm) of cauliflower also yielded significantly (P < 0.01) higher (5.08 t/ha) curd yield than that of 60 x 45-cm (3.87 t/ha). A bivariate analysis of both crops showed that increasing plants population either of cauliflower or maize gave the higher yield. Falling apart of the non-confidence region of 26,666 maize with 74,074 cauliflower plants/ha with 40,000 maize with 74074 cauliflower plants/ha (higher maize yield) and 20,000 maize with 74,074 cauliflower plants/hn (higher cauliflower yield) demonstrate that 26,666 maize population with 74,074 cauliflower population/ha was the more appropriate  mix to get balance yield of cauliflower and maize.
