From: Farmer’s choice of seeds in four EU countries under different levels of GM crop adoption
Yield development in maize production per hectare from 1995–2011 in USA (red dashed line, filled circles), ‘Europe’ (green dotted line, crosses), and Spain (purple solid line, filled squares, as a GM-adopting country). (Linear regression analysis of yields per year: USA: y = 1430x + 77493; R2 = 0.732; p<0.001; “Europe”: y = 1530x + 82521; R2 = 0.412; p=0.005; Spain: y = 1165x + 85512; R2 = 0.63; p<0.001).
