The present experiment is carried out at Agriculture research Station, Sonapur –Gadchiroli during the year 2019-20 with six different spacing (60 × 30, 60 × 45, 90 × 30, 90 × 45, 120 cm × 30 cm and 120 cm x 45 cm) in Randomized block design with four replication, with the objective to determining the effect of plant spacing on the growth and yield of sweet potato. The results revealed that, maximum growth was recorded viz., vine length (149.10 cm), and number of branches per vine (7.80) was recorded maximum in wider spacing 120 cm x 45cm however, the intermodal length of vine was found to be non significant. The maximum yield per vine was obtained in the wider spacing 120 cm x 45 cm (405.48 g). However, calculating the yield data per plot and per ha got different results. The maximum tuber yield per plot (13.09 kg) and per ha (13.47 t) was recorded with the spacing of 60 cm x 30 cm which was statistically at par with the spacing 90 cm x30 cm and 120 cm x 30 cm. Increasing plant density from 2 plants m-2 (120 cm x 45 cm) to higher level of 6 plants m-2 (60 cm x 30 cm) increased the production of total tuber yield from 13.47 t ha-1. In conclusion, the results of the study revealed that the highest plant density of 6.00 plants m-2 (60 cm x 30 cm) despite decreasing the yield per plant, resulted in the production of the highest tuber yields ha-1
