The plant growth and nitrogen uptake pattern of a crop with a short production period (iceberg lettuce) grown at two different periods in the growing season and a crop with a long growth period (gherkins) are analyzed in order to formulate an improve

Applying nitrogen (and/or other nutrients) through the irrigation system during cultivation is called fertigation. The system offers a means to adjust the supply of N to the nutritional need of the crop, thus limiting NO3 leaching and luxury consumpt

Three [unnamed] cultivars were grown successively during March to May, June to July, and July to August 1983 on a sandy soil. For each of these field experiments the treatments were: no N application, and fertilization with various amounts of ammoniu

For the last five years, field experiments have been conducted on different soil types, in which the response to nitrogen of different leafy vegetables was tested in terms of nitrate content and yield. Before each culture the total amount of mineral
