Claim · model-written summary
The O3-induced yield loss of HUW-234 was significantly lower under rainfed conditions (0.6 %) than under irrigated conditions (10.6 %).

e7“threaten the ability of wheat yields to meet the growing demand for food production in India”
e0“Under rainfed conditions for the years 1996–2005, the mean water-stress-induced and O3-induced yield losses for HUW-234 were 13.3 % and 0.6 %, respectively”
e1“The latter was a significant decrease from the mean O3-induced yield loss of 10.6 % modelled under irrigated conditions (i.e. no water stress)”
