An experiment was carried out to study the effect of planting dates and plant spacing on growth and yield attributes of sweet potato cv.CO-3-4 at Horticulture Farm, Department of Horticulture, Rajasthan College of Agriculture, MPUAT, Udaipur during May, 2016 to November, 2016. The experiment was comprised of four levels of plant spacing on four different dates with Factorial Randomized Block Design. The results revealed that the vegetative growth and yield attributes are significantly influenced by various level of spacing. The minimum time taken for 50 % sprouting (11.58 days), maximum vine length (195.92 cm), leaves per vine (91.74), tuberous per plant (5.21), tuber length (18.86 cm), tuber diameter (9.73 cm) and yield per ha (29.97 t per ha) were recorded in wider spacing 40 x 40 cm (treatment P4).The planting dates also influenced vegetative growth and yield parameter of sweet potato. The minimum time taken for 50 per cent sprouting (11.75), maximum vine length (184.58), leaves per vine (88.50), tuberous per plant (5.08), tuber length (17.39 cm), tuber diameter (8.85 cm) and yield (30.50 t ha-1) were recorded in 10th June of planting (treatment S3).The interaction of planting dates and plant spacing also significantly influenced on sweet potato. The minimum time taken for 50 per cent sprouting, maximum vine length (226.67 cm), leaves per vine (100.33), tubers per vine (6.33), tuber length (23.00 cm), tuber diameter (10.43 cm) and yield (34.37 t ha-1) were recorded in treatment P4S3 (40 x 40 cm and 10th June ).
