To evauluate oat varieties which grew well under sodicity and salinity in the previous SAGIT oat project (UA416), and are hence potentially tolerant to saline/sodic soil.
To recommend to farmers saline/sodic-tolerant oat varieties.
Key messages
Once again, we have demonstrated the versatility of oats, this time under salinity/sodicity and moisture stress in the field
Large differences in grain yield (5-fold under salinity/sodicity and 35-fold under moisture stress) and biomass yield at heading at both trial sites indicate strong genotypic variation between oat varieties/lines for tolerance to these stressors
The oat grain yields at Redhill, a strongly saline-sodic site with high subsoil boron (see data in Appendix 1), were impressive, especially in view of the low growing season rainfall (170mm, 6.8”) in 2019. For example, Bannister, Eurabbie and SARDI 06204-16 yielded 3.6 t/ha, compared with Compass barley 2.7 and Aurora durum wheat 1.2 t/ha. In addition, phosphorus, magnesium and zinc were deficient at both sites.
