Response of Hydroponic Lettuce Cultivars to Different Treatments of Nitrogen : Growth and Foliar Nitrate Content

The nitrogen requirements of lettuce (Lactuca sativa L.) cultivars for obtaining plants of a high phenotypical quality and low nitrate foliar content were studied in this research. Butterhead (Divina and Prima cvs.) and loose-leaf (Grand Rapids and Brisa cvs.) lettuces were grown in a modified hydroponic floating system. Plants were subjected to four… CONTINUE READING
