Abstract

Oat has much privileged sodium ion levels than wheat, soybean, cotton, and other seasonal crops. Oat cultivation is still well thought-out to stand for a supportive biological assess to recover saline lands due to its high capability to accrue salt ions in its straw, which is widely used as forage for livestock. Seeds of Oat (Avena sativa) were sown in a pot study to different combinations of salinity and sodicity [S0=4.70dSm-1+ 19.12 (mmol L-1)1/2, S1= 9.02dSm-1 +30.65 (mmol L-1)1/2 and S2= 11.35 dSm-1 +34.69 (mmol L-1)1/2]. Seven oat varieties namely Bulbin, S-2000, Dilawar, PD2LV65, No.667, Bob and Cyprus were used for screening against salt tolerance. The leaset % decrease in grain yield (35.24) was attained in S-2000 oat variety than other varieties. Therefore, this oat variety showed minimum loss due to toxic effects of salinity cum sodicity. Dilawar oat variety attained the highest grain yield (1.38 tha-1) under S2 [11.35dSm-1 +34.69 (mmol L-1)1/2]. Bulbin oat variety received the least position (1.21tha-1) in this salinity level. % decrease at S2 over S0 was indicated salt tolerance of oat varieties. Bob oat variety attained the lowest % decrease at S2 over S0 (42.27). Therefore, this variety had the maximum salt tolerance other than six oat varieties under this experiment
