The effects of nitrogen fertilization (range: 0–240 kg N/ha; end of April) and supplemental irrigation (3 applications; May–June) on growth, biomass and seed yield of Cynara cardunculus were investigated in a dry environment of central Greece (Velestino, 2008/2009) during the crop’s second growth cycle. The growth was thththnd rd monitored by destructive sampling on April 28, May 19, June 5, July 2and August 3(final harvest) and it was analyzed using sigmoid curves. Nitrogen input –...
