Raising the Yield Potential: by Selection or Design?

  • L. T. Evans
Part of the Basic Life Sciences book series (BLSC, volume 26)


The most appropriate measure of yield has changed in the past, and may well continue to do so as agriculture itself evolves. The earlier criterion of number of grains harvested per grain sown has been largely displaced by yield per hectare per crop, which is the basis of the following discussion. But in multiple cropping sys-tems, especially in the tropics, yield per hectare per day is becoming ever more important, while yields per unit of applied energy or water or phosphorus or labor are also important considerations.
