A field experiment was conducted on medium black soil to study the screening of bunch groundnut varieties for physiological growth parameters and yield attributes under rainfed condition at Main Dry Farming Research Station, Junagadh Agricultural University, Targhadia, Gujarat, during kharif- 2017-18 to 2020-21. The experiment comprising of fourteen bunch groundnut varietal screening., viz. T1 JL-501, T2 TG-26, T3 TLG-45, T4 TPG-41, T5.TAG-24 T6TG-37 A, T7 GJG-31, T8 GJG-9, T9, GG-2, T10 GG-4, T11 GG-5, T12GG-6,T13GG-7 and T14 GG-8with three replications laid out in randomized block design. In pooled results of these research study indicated that significantly higher pod yield was obtained in variety JL-501 (3304 kg ha-1) which was remained at par with TG-26, TPG-41, TAG-24 and TG-37 A, while significantly higher haulm yield (4375 kg ha-1) was obtained in GG-5 and which was remained at par with JL-501, TG-37 A, GJG-31, GJG-9, GG-2, GG-4, GG-6, GG-7, GG-8. In this study showed that JL-501 was gave higher pod yield as compare to other bunch groundnut varietal screening due to pod dry weight (15.6 g. plant-1), total dry weight (43.9 g. plant-1), leaf growth rate (2.85 gm-2 day-1) and crop growth rate (13.3 gm-2 day-1) is higher as compare to other bunch groundnut varieties. Similarly, maximum net return (138448 Rs. ha-1) and B: C ratio (3.14) were obtained in variety JL-501 as compared to other bunch groundnut varieties
