Knol-khol varieties with different plant spacing were evaluated for growth and yield. Highest plant height (26.33 cm), plant spread East-West and North-South (36.89 cm and 36.48 cm, respectively) and leaf area (261.45 cm2 ) was observed with the plant spacing of 30 cm × 30 cm. Whereas, maximum stem thickness (11.90 cm) was recorded with variety Purple Vienna. Minimum days taken (52.08) for harvesting, maximum yield per plot (10.33 kg) and per hectare (36.15 t) were recorded with the plant spacing of 20 cm × 20 cm. Though, plant spacing of 30 cm × 30 cm showed best for fresh weight of knob (308.25 g). Among varieties, maximum fresh weight of knob (277.36 g), yield per plot (9.51 kg) and per hectare (33.28 t) were found with variety Purple Vienna. From the findings of the study conducted, it is inferred that 20 cm x 20 cm plant spacing and variety of Purple Vienna is most suitable for knolkhol cultivation under North Gujarat condition.
