Field experiments to identify suitable planting method under potato + maize system in the  high hill (2200 m) of eastern Nepal Sindhuwa, Dhankuta, was conducted during 2000 and  2001 seasons for the potato variety Hale and maize variety Ganesh 1. Of the different  planting methods tested, significantly the highest yield of potato (15.5 t/ha) was recorded  from the alternate row planting followed by recommended practice and flat row planting.  Early emergence (by 7-12 days) was in farmers' practice, whereas uniform plants (1-5  scale) observed in flat row and double row planting. Maize did not follow this trend.  Double row and farmer's practice favored good ground coverage (80-95%) by potato  plants, which attained height from 49.8cm (farmer's practice) to 56.8 cm (flat row).  Number of main stems/plant was higher in all treatments, except farmer's practice. Similar  trend was followed in tuber numbers. Maturity of crops did not depend on planting  methods. Final stand of potato ranged between 46.9 (alternate row) and 68.6 thousand/ha  (farmer's practice). Late blight and bacterial wilt infection was higher in the farmers'  practice. The height of maize plants was significantly differed between sole cropping (220  cm), which yielded higher followed by alternate row (183 cm) and flat row plantings.  Gross income from maize and potato was higher in flat row planting. The data revealed that  alternate row and flat row planting methods were superior over the common farmers'  practice and the recommended practice, so the identified planting methods were  recommended.
