Sunflower (Helianthus annuus L.) is an important oilseed crop of India. There has been consistent
decline in its production for last one and a half decade. The production has declined from 1.46 million
tonnes (m t) in 2007-08 to 0.23 m t in 2020-21. A mission mode approach is required to increase
the area and productivity of sunflower in the country. Relative Spread Index (RSI) and Relative Yield
Index (RYI) were estimated for 181 districts to identify the potential areas. Based on RSI and RYI
values of 250 and 125, these districts were grouped into four categories viz., most efficient, efficient,
moderately efficient and inefficient. The inefficient districts were ignored. Of these, 11 and 13 districts
were selected for productivity enhancement and area expansion, respectively. For these selected 24
districts, district-wise technologies were mapped. Front line demonstrations (FLDs) were conducted
in six districts. In all the districts, FLDs plots recorded higher seed yield and gross monetary returns
compared to farmers’ practice plots. Further, the strategies for productivity enhancement and area
expansion were discussed.
