Sunflower (Helianthus ann~us) is newly emerging oilseed crop in Nepal It is grown either
sole or intercrop with maize/ sugarcane/groundnut etc. A field experiment was conducted at
Oilseed Research Program, Nawalpur Sarlahl during 1998 andl999 son to determine the most
compatible and remunerative inter crop · combination of sunflower with other crops. The
experiment was conducted on sandy loam soiltmder irrigated condition in spring season and
rainfed condition in rainy season In general Ute· sunflower seed yield was higher in sole
cropping system in both seasons. Sole sunflower recorded mean seed yield of 1850 kg/ha .in
spring season and 162 kg/ha in rainy season. Among Ute different intercroppiug system,
swlflower + groundnut (1 :3) row proportion recorded highest mean net returns of
Rs.23219/ba wiU1 highest mean LER (1.36). In rainy season, sole maize recorded the highest
mean net returns of Rs.9929/ha. Sunflower+ sesame (1:3) row proportion recorded highest
mean LER (1.42) in rainy season.
