The experiment was conducted at Joydebpur to find out the effect of seed size and spacing on yield of exportable quality potato. Reports showed that larger seed (110-120g) and wider spacing of 70 X 40 and 70 X 30 cm gave significantly higher yield as well as higher proportion of larger sized (>55m) tubers compared to smaller seed tubers and closer spacing.

To produce higher proportion of exportable tubers with improved qualities through agronomic manipulation..

The experiment was conducted at Joydebpur with the standard variety BARAKA, Whole seed tubers of three sizes viz, 30-40, 70-80, and 110-120g were planted at three spacings viz. 70x20, 70x30 and 70x40 cm. The unit plot size was 5.4x3m. The tubers were sown on 6 December 2005 and the crop was fertilized with 350-250-270-120-60kg/ha of urea, TSP, MP, gypsum and Boric acid, respectively, Before final preparation of the land, cowdung @ 10 t/ha was applied. The experiment was laid out in RCB (factorial) design with three replications. The crop was grown following usual cultural practices and harvested after 90 days of planting. After harvest the tubers were kept under natural storage condition to study their post harvest behavior.
