Nevertheless, few findings are presently available on fully-irrigated quinoa growth and productivity grown in arid Mediterranean area. Field experiments conducted in Syria for two growing seasons (2017/18 and 2018/19) determined the response of quinoa crop (ICBA-Q5 cultivar) to five different transplanting dates (TD) (December, January, February, March, and April) and four nitrogen fertilizer levels (0, 90, 180 and 270 kg N ha<sup>-1</sup>). Main findings showed that quinoa had a good adaptation (up to 5.30 and 15.9 t ha<sup>-1</sup> of seed and dry matter yields, respectively) to very low N-inputs, with a high capacity to evapotranspirate (ETc), resulting in high crop coefficient (kc). ETc and kc varied in the range of 590-1136 mm and 0.37-2.05 among the TDs, respectively. Moreover, quinoa growth and productivity were highly affected by TDs, and varied from year to year, influenced mainly by temperature. Emphasis in future experiments should probably be given to TD in December, which exhibited a high degree of consistency over years with high crop performance, and to TDs in January and February, which performed extremely well in the first year.</p>}, number={2}, journal={Italian Journal of Agrometeorology}, author={Mubarak, Ibrahim and Janat, Mussaddak}, year={2021}, month={Jan.}, pages={77–89} }
