An example of productivity, showing the yield output curve in response to the increasing use of fertiliser in rice, potato, and vegetable cultivations. Crop output increases with increasing amounts of right fertiliser mixture, but at a certain point [MC = M × R], it starts to plateau and may even decline. Thus, more is not always better (adapted from Wimalawansa et al., [51, 66])
