The relative performance of individual sprouts, sprouted whole and cut tubers were evaluated for growth and yield of potatoes. By using individual sprouts, the seed weight was reduced to 6.8 q/ha as compared to 40.1, 20.1 and 10.3 q/ha for whole tubers, half tubers and quarter pieces, respectively. The number of shoots, stem girth, height, number of leaves, etc., of plants from individual sprouts were less than from other planting-materials. The yield per hectare was also less for individual sprouts than for plants from whole tubers or half tubers, but it was on a par with quarter pieces. However, the seed: yield ratio was highest (1: 5.6) in plants from half tubers (top end), closely followed by individual sprouts (1: 5.1), whereas it was 1: 3.3, 1: 4.5, and 1: 5.0 in plants from whole tubers, half tubers (base end) and quarter pieces, respectively.
