Sunflower is an introduced crop in India. Difficulty in dehulling the seeds at the household level and lack of awareness about its food value are the main reasons for the kernels not being used in the diets of people who grow them. Different types of treatments to dehull the seeds such as, wet dehulling, manual and mechanical methods were screened. The removability of hull was poor in all wet dehulling pretreatments that were studied. Sunflower seeds that were dehulled by mechanical method was found most acceptable method among other methods used. The calculated cost of the dehulled sunflower seeds was estimated to be Rs. 80/kg ($1.27). Three varieties namely, KBSH 44, KBSH 41 and Confectionery-1 were employed. Physical characteristics of the seed such as, seed size, weight of 100 seeds, volume, bulk density, hulls and kernel recovery by mechanical and manual methods was measured. All the genotypes exhibited significant differences in their physical characteristics.

Key words: Sunflower, dehulling, physical characteristics, sunflower kernels
