Agronomic Practices and Performances of Quinoa under Field Conditions: A Systematic Review

Abstract

Quinoa (Chenopodium quinoa Willd.) is one of the most popular emerging food crops in the Andean region. It is tolerant to environmental stresses and characterized by interesting nutritional traits. Thus, it has the potential to contribute to food and nutrition security in marginal environments. In this study, we conducted a systematic review integrated with a bibliometric analysis of cropping practices of quinoa under field conditions. The analysis is based on published data from the literature relating to the period 2000–2020. A total of 33 publications were identified, revealing that scientific research on the agronomic practices and performances of quinoa under field conditions is still limited. Africa, Asia, and Europe were the leading research production sites in this field and together provided over 81% of the total scientific production. There were no papers from the Australian continent. The number of papers screened dealing with tillage and weed control management was very limited. The keyword co-occurrence network analyses revealed that the main topics addressed in the scientific literature related to the effect of “variety” and “deficit irrigation”, followed by “water quality”, “fertilization”, and “sowing date” on seed yield. Results from this study will permit us to identify knowledge gaps and limited collaboration among authors and institutions from different countries. Salinity, sowing density, and sowing date were the agronomic interventions affecting productive response the most.

Quinoa Phenotyping Methodologies: An International Consensus

“…More detailed recommendations for specific situations can be found in the book "Quinoa: Improvement and Sustainable Production" [79]. Although there are no clear guidelines for some of the following crop management aspects yet, a research gap that needs to be addressed, it is advisable to follow strategies that are successful for others growing quinoa under similar environmental conditions and soil types [13,80].…”

Phenotypic and Quality Traits of Chickpea Genotypes under Rainfed Conditions in South Italy

“…These ecotypes are characterized by excellent resistance to different environmental conditions but are low-yielding and heterogeneous with regards to morphological traits, such as grain size and, often, very sensitive to disease incidence and parasitic attacks [14]. Today there is a growing interest in grain legumes, representing an important alternative protein source to meat for the future [16][17][18].…”

“…In 2020, more than 5612 hectares were cultivated in Italy for a total production of 4.98 thousand tons, with an average of around 0.89 tons per hectare [5]. The interest in grain legumes, which are a major alternative source of protein to meat for the future, is increasing at present [7][8][9].…”
