Two Unnati and Surkhet Local three Oct 4, 24 Nov 14 were tested two factorial RCBD design year 2018 A.D. Data consisted growth attributes like plant height, branch per plant, no. siliqua aborted abortion percentage such as biological yield, biomass seed harvest index test weight. Statistically no difference found between whereas differences dates. Result showed that among varieties, highest (8.59 q/ha) obtained than (8.54 q/ha). In case dates, higher 4 sown (15.93 followed by (7.47 (2.29 q/ha).The early due shorter vegetative longer reproductive phase. The comparison mean values for interaction variety date had (16.33 same (15.54 Based result obtained, Local*Oct performed better Dang condition.
