Over fertilization limits lettuce productivity because of osmotic stress
2015
Chilean Journal of Agricultural Research
It is customary that growers apply high doses of nutrients to the soil in order to achieve high yields, with detrimental consequences for the environment; but no information exists with regards to the crop response to high fertilization levels. To evaluate the physiological response of lettuce (Lactuca sativa L.) to various root zone nutrient concentrations (expressed as electrical conductivity, from 0.6 to 10 dS m -1 ), a replicated experiment was conducted using increasing concentrations of
