Decrease in plant spacing from 20 to 15 and 10 cm increased stems/unit area, plant height, haulm weight, total as well as number of different size tubers/unit area, yield of tolal as well as of >25–50, >50–75 and >75 g size tubers. Fertilizer dose used in the present experiment could not influence any of these parameters. With increase in crop duration from 75 to 85 days there was significant increase in haulm weight and yield of >75 g and tolal tubers, while other parameters were not influenced.
