What can we learn from Barley Waterlogging damage?
Barley Waterlogging Damage: What can we learn?
ï‚· Water logging during late stem elongation (the critical period) reduced grain number significantly in early sown Planet barley and severe stress resulted in complete crop failure.
ï‚· 6 row slower developing winter barley had more viable stems and more grains per spike making recovery better from waterlogging.
ï‚· 6 row winter barley achieved 9.9t/ha in the absence of significant water logging and 3.1t/ha under severe water logging stress.
ï‚· RGT Planet yielded 7.8t/ha in the absence of significant water logging and 0.3t/ha under severe water logging stress.
ï‚· Apart from sowing earlier and using slower developing genetics, there was little evidence of genetic differences in field waterlogging tolerance.
ï‚· Water logging was more detrimental to barley than wheat on site.
ï‚· Little evidence to suggest more N recovered yield from water logging and/or later sowing, the lowest N treatment (10 units of N) yielded 5.65, 50 Units of N yielded 7.11 and the highest N treatment (290 units of N) yielded 6.32t/ha.
