The experiment on potato cv. Kufri Badshah was conducted during autumn season of 1994–95 and 95–96 at CCSHAU, Hisar. Treatments consisted of combinations of six plant densities (47,619–1,66,666 plants/ha) and three plant geometries (50, 60 and 70 cm apart rows). The study reveal that plant height, stems/m2 and tuber number/m2 increased with increase in plant density from 47,619 to 1,66,666 plants/ha, while leaf area index and dry weight of foliage increased up to a plant density of 1,21,212 plants/ha. Plant geometry had no effect at all. Yield of over size tubers decreased, while that of under size increased with increase in plant density up to 1,66,666 plants/ha. The yield of seed size tubers as well as total tuber yield increased with increase in plant density up to 1,21,212 plants/ha, however, plant geometry did not influence the tuber yield significantly (except yield of under size tubers.)
