A field investigation was carried out at the Agricultural Research Station, Tornala (Professor Jayashankar Telangana State Agricultural University), Telangana, India during kharif season of 2021-22 to evaluate the performance of cotton cultivars under high density planting system (HDPS). It consisted of two cultivars viz., ADB-39 under 60cmx20cm and NCS-2778 under 80cmx20cm spacing and the data was analysed through two sample t-test. The final plant population was higher with ADB 39 (77,579 plants ha-1) than NCS 2778 (58,368 plants ha-1). The hybrid NCS-2778 produced significantly higher boll weight (4.24 g) and kapas yield (2760 kg ha-1) than variety ADB-39 (2485 kg ha-1). Further, ginning % was also found to be significantly higher with NCCS-2778 than ADB-39 (31.7g). Though NCCS-2778 accrued higher cost of cultivation by ₹ 6207 ha-1, it gave higher gross and net returns by ₹19,250 and 13,403 ha-1 than ADB-39. Thus, NCCS-2778 can be preferred hybrid than ADB-39 variety under HDPS in rainfed alfisols.
