Mustard is an important oilseed crop in India, and identification of suitable genotypes and sowing windows is essential for expanding its cultivation in non-traditional regions like Southern Telangana. A field experiment was conducted on introduction of mustard (Brassica juncea L.) to nontraditional area of Southern Telangana Zone and evaluated the performance of different genotypes of mustard under varied sowing dates during Rabi 2020-21, 2021-22 and 2022-23 at Regional Agricultural Research Station, Palem, Southern Telangana Zone. The study was carried on the sandy loam soils. This experiment was taken up in split plot design (SPD) with three genotypes viz., V1- DRMRIJ 31, V2- NRCHD 101 and V3- Black gold as main treatments. Four sowing dates D1- 15^th October, D2- 5^th November, D3- 25^th November and D4- 15^th December as sub treatments replicated three times.  Observations on plant height (cm), number of siliqua plant^-1, length of siliqua (cm), number of seeds siliqua^-1, test weight (g), seed yield (kg ha^-1), straw yield (kg ha^-1), harvest index (per cent) were recorded. The pooled results of these three years experimentation it was revealed that, V1- DRMRIJ 31 and V2- NRCHD 101 recorded significantly on par seed yield 769 and 699 kg ha^-1 respectively over the seed yield obtained by V3- Black gold (596 kg ha^-1). Similarly, Pooled results of four sowing dates revealed D1- 15^th October and D2- 5^th November was found higher and onpar seed yield with 913 and 826 kg ha^-1 respectively over the D3- 25^th November and D4- 15^th December sowing dates ) under irrigated conditions of Alfisols. Inconclusion DRMRIJ 31 and NRCHD 101 may be recommended with sowing date from 2^nd fort night of October to first week of November for Southern Telangana Zone.
