Productivity and efficiency are key performance indicators of improved seeds. Efficiency differences explain part of … the variation in productivity. Improved seeds may affect efficiency because farmers often do not apply inputs at optimum …. Improved seeds therefore not only directly affect productivity but also indirectly through efficiency. If productivity and …
