In a field trial at the Vegetable Research Farm, Haryana Agricultural University, Hissar intrarow spacing of 15 cm gave the higest tuber-yield in potato var. Kufri Chandramukhi. With wider intra-row spacing of 25 cm and 80 g seed-size the production of ‘A’ grade (above 50 mm) tubers were also improved. The closer spacing i.e. 15 cm, higer yields of ‘B’ (25 mm to 50 mm) and ‘C’ grade (below 25 mm) tubers was obtained. The height of plant and number of stems per hill were also higher in 15 cm spacing and 80 g seed-size. It was concluded that an optimum plant spacing (55 cm × 15 cm) with the seed-size of 80 g gave best performance under arid conditions prevailing at Hissar.
