Assessment of the changes in seed yield and nutritional quality of quinoa grown under rainfed Mediterranean environments

Climate change is considered a serious threat to agriculture and food security. It is linked to rising temperatures and water shortages, conditions that are expected to worsen in the coming decades. Consequently, the introduction of more drought-tolerant crops is required. Quinoa (Chenopodium quinoa...

It is linked to rising temperatures and water shortages, conditions that are expected to worsen in the coming decades. Consequently, the introduction of more drought-tolerant crops is required. Quinoa (Chenopodium quinoa Willd.) has received great attention worldwide due to the nutritional properties of its seeds and its tolerance to abiotic stress. In this work, the agronomic performance and seed nutritional quality of three quinoa varieties were studied during two consecutive years (2019-2020) under three water environmental conditions of Southwestern Europe (irrigated conditions, fresh rainfed, and hard rainfed) with the goal of determining the impact of rainfed conditions on this crop performance. High precipitations were recorded during the 2020 growing season resulting in similar grain yield under irrigation and fresh rainfed conditions. However, in 2019, significant yield differences with penalties under water-limiting conditions were found among the evaluated environmental conditions. Furthermore, nutritional and metabolomic differences were observed among seeds harvested from different water environments including the progressive accumulation of glycine betaine accompanied by an increase in saponin and a decrease in iron with water limitation. Generally, water-limiting environments were associated with increased protein contents and decreased yields preserving a high nutritional quality despite particular changes. Overall, this work contributes to gaining further knowledge about how water availability affects quinoa field performance, as it might impact both seed yield and quality. It also can help reevaluate rainfed agriculture, as water deficit can positively impact the nutritional quality of seeds.The authors gratefully acknowledge the financial support received from Junta de Extremadura, the European FEDER Funds (GREENHOPE), and from the Ministerio de Ciencia e Innovación (MICINN, Spain) and the Agencia Estatal de Investigación (PID2019–105748RA-I00 AEI/10.13039/501100011033 and the NutriCrop Spanish Network RED2022-134382-T), the FPI UAM Fellowship Programme 2019 (to SG-R), and the Ramón y Cajal Programme 2019 (to MR)Peer reviewedFrontiers MediaJunta de ExtremaduraEuropean CommissionMinisterio de Ciencia e Innovación (España)Agencia Estatal de Investigación (España)NutriCropMinisterio de Ciencia, Innovación y Universidades (España)Fernández, Nieves [0000-0002-5860-2173]Consejo Superior de Investigaciones Científicas [https://ror.org/02gfc7t72]202420242023info:eu-repo/semantics/articlehttp://purl.org/coar/resource_type/c_6501Publisher's versioninfo:eu-repo/semantics/publishedVersionhttp://hdl.handle.net/10261/356551reponame:DIGITAL.CSIC.
