“…Quinoa is one of the main food crops in the Andean mountains, but during recent times there has been increased interest for the product in the United States, Europe, and Asia (Jacobsen, 2003). Quinoa is a good source of protein and can be used as a nutritional ingredient in food products (Gonzalez et al, 2012). The Organization of the United Nations for Food and Agriculture (FAO) has declared the year 2013 as the year of the quinoa.…”

A field experiment was conducted to determine the effects of fertilization and tillage on growth, yield and quality of quinoa crop (Chenopodium quinoa Willd.). The agronomic performance and nutritive value of quinoa was analyzed in order to define alternatives to local forages for dry-season feeding of ruminants in the Mediterranean region. The experiment was laid out in a split-plot design with two replicates, two main plots [conventional tillage (CT) and minimum tillage (MT)] and sub-plots (fertilization treatments: control, cow manure, inorganic fertilization 100 kg ha -1 (N1) and inorganic fertilization 200 kg ha -1 (N2)). The results indicated that quinoa growth was influenced by both tillage and fertilization. The lowest height and dry weight were found under MT. Moreover, the lowest height and dry weight (8205 kg ha-1 and 8020 kg ha -1 for CT and MT, respectively) were found under control treatment (no-fertilization). Concerning the nitrogen content there were no significant differences between CT and MT systems. In addition, the highest quinoa nitrogen content was observed for N2 treatment (200 kg N ha -1 ). Moreover, the highest nitrogen content was measured at 150 DAS. Concerning the crude protein content, there were no significant differences between CT and MT systems. In addition, there were significant differences in crude protein between fertilization treatments. The greatest value was observed for N2 treatment. Moreover, the highest crude protein yield (2481 kg ha -1 and 2356 kg ha -1for CT and MT, respectively) and acid detergent fibre (ADF) were found under N2 treatment. In addition, ash was not influenced by both tillage systems and fertilization treatments. Data indicate that quinoa crop could be used as alternative to legumes for protein production to feed ruminant animals.

“…), is a stress-tolerant plant, cultivated along the Andes, from about 3000 B.C. It is still cultivated in Peru, Bolivia, Chile, Ecuador, Colombia and Argentina (Gonzalez et al, 2012). Its grains have a high-protein content with abundance of essential amino acids, and a wide range of vitamins, minerals and saponin and it is a promising worldwide plant for human consumption and nutrition (Bilalis et The genus Amaranthus includes about 60 species, most of which are cosmopolitan weeds associated with dif iculties in cultivation practices after soil disturbance and seed exposure to light.…”

The effect of organic and inorganic fertilization on yield and biomass quality of two species: quinoa (Chenopodium quinoa Willd.) and green amaranth (Amaranthus retro lexus L.) was studied in this paper. The agronomic performance and nutritional value of quinoa and green amaranth was analyzed in order to establish them as alternatives to local forages for dry-season feeding of ruminants in the Mediterranean region. The experiment was laid out in a split-plot design with two replicates, two main plots (quinoa and amaranth) and four sub-plots (fertilization treatments: control, inorganic fertilization, compost and cow manure). The results indicated a clear superiority of quinoa over the amaranth in height and dry matter, while there were no differences in the nutritional value of biomass between the two species. In general, fertilization had a positive impact on growth and yield of both species. Fertilization with compost showed higher values in most quality traits of biomass in the quinoa crop, while inorganic fertilization had better results in amaranth. The results of this study suggest that quinoa and green amaranth crops could be used as an alternative feed over spring legumes in dry-warm Mediterranean areas.

“…Inca people call it the mother grain. Its grains have a high protein content (14-16%) with excellent amino acid balance (Gonzalez et al, 2012) and a wide range of vitamins and minerals (Valencia-Chamorro, 2003). The Food and Agriculture Organization of the United Nation has declared the year 2013 as the international year of quinoa (FAO, 2013) due to its potential contribution to the fight against hunger and malnutrition.…”

multi environmental trial involving five quinoa genotypes i.e., KVL-SRA2, KVL-SRA3, Regalona, Q-37 and Q-52 was conducted along the North Western Coast of Egypt. The eight tested environments included two sites in the first season of 2014/2015 i.e. irrigated Matrouh and rainfed Matrouh, while in the second season of 2015/2016 there were six sites including three rainfed sites of Ras El Hekma, El Neguilla and Matrouh as well as an irrigated site in Matrouh with three planting dates i.e., 1 Nov.,15 Nov., and 1 Dec. Grain yield was significantly influenced by both genotypes and environments; Regalona genotype produced the highest grain yield in most of the studied environments (6 out of 8 environments) with the highest grain yield of 3.08 t/ha in irrigated Matrouh site in the first season. Moreover, it showed more drought tolerance as compared to the other genotypes. The environment effect was the major source of variation as compared to the genotype and genotype × environment interaction effects, and attributed to 88.5% of the total variation in the grain yield. Two-mode pattern analysis of the environment-standardised matrix of grain yield revealed three genotypic groups of different response pattern across environments. In general, the grain yields of the genotypes were lower under rainfed conditions as compared to irrigated conditions, except for Matrouh in the second season for the late irrigated planting dates i.e., 15 Nov. and 1Dec. The high tolerance of quinoa to drought makes it an excellent choice for the diversification of future agriculture in the North Western Coast of Egypt and other regions with similar harsh conditions.
