The study was conducted in Nilgaon and Chamurakandi of Sylhet Sadar Upazila under Sylhet district during the 2018-2019 crop seasons. Three orange fleshed sweet potato varieties (BARI SP-04, BARI SP-11 andBARI SP-12)and a local genotype were used in this study. The ultimate purpose of the experiment was to investigate the yield potentiality, suitability and acceptability of those varieties and genotype. The experiment was performed using 10ft x 10ft plot size with 3 replicas following the RCB design. The study showed hat BARI SP-12 performed better and local genotype performed least at both places. In Nilgaon BARI SP-12 gave the highest yield (35.27 t ha-1) followed by BARI SP-04 (34.14 t ha-1),BARI SP-11 (32.26 t ha-1) and the lowest yield was documented in local genotype (24.10 t ha-1). BARI SP-12 also produced the highest yield (32.01 t ha-1) at Chamurakandi followed by BARI SP-04 (28.43 t ha-1),BARI SP-11 (28.00 t ha-1) and the lowest was documented in local genotype (19.46 t ha-1).However, the mean yield of two places appeared the highest in BARI SP-12 (33.64 t ha-1) followed by BARI SP-04 (31.28 t ha-1) and BARI SP-11 (30.13 t ha-1) and the lowest was found in local genotype (21.78 t ha-1). The average foliage yield of two places ranged from 4.82 to 5.38 t ha-1. And no significant variations were found in foliage yield and foliage coverage (%) at both places.In the case of organoleptic assessment of storage roots and leaves, BARI SP-04 was the best choice by the respondents due to its appearances, color, taste, texture and fiber content; BARI SP-12 also got merely similar ranked by the respondents. Considering the yield potential and community acceptability, both BARI SP-04 and BARI SP-12 are suitable and potential for homestead food production system in north eastern region of Bangladesh.
