Abstract: Globally, India occupies fourth position in oilseed production. Despite this, India has a persistent gap between the demand and supply of oilseed. Assam occupy 1.09 per cent of the total oilseed cultivated area in India, whereas its contribution to national production was only 0.60 per cent. Lakhimpur is a major oilseed-producing district of Assam; the yield of oilseed is comparatively low. Currently, it is observed that the Lakhimpur district yield of oilseeds is steadily increasing. Against this background, the present study systematically examines the growth rate of harvested area, production and yield of oilseeds in the Lakhimpur district of Assam. The study primarily covered the period from 1997-99 to 2024-25, and data were collected from the Indiastat database. The exponential function and compound annual growth rate were used to estimate the growth rate of harvested area, production and yield of oilseeds. To detect the structural break, the time series graph and the Bai-Perron test were used for the study. The oilseed yield gap is examined by using the graphical method and the percentage method. The study revealed that the compound annual growth rate (CAGR) of the harvested area, production and yield of oilseeds was 1.84. 5.94 and 4.04 % respectively. Thus, the study also found that a major statistically significant structural break occurred in the production of oilseed. After the structural break, the CAGR steadily increased. The oilseeds yield gap was found to be - 0.83 %, which indicates Lakhimpur district's oilseed cultivation performance is better than the All-Assam level.
