A field experiment was conducted to study the feasibility of advancing the sowing of intercrops in rainfed sunflower under different nitrogen levels. Pure crop of sunflower recorded the maximum yield. Yield of sunflower was reduced when cowpes or groundnut was grown as an intercrop and the reduction increased with the period of advancement of intercrops. An extra dose of 10 kg N/ha in addition to the recommended dose of 30 kg N/ha recorded the maximum yield.
