“…Protein content did not differ significantly among amaranth species and ranged from 20.75 % to 21.56 % in dry mass. The same pattern is established with other indicators of nutritional value comparing species of amaranth (Andini et al, 2013)It can be stated that the soil and climatic conditions of the experiment were quite favorable for the accumulation of nutrients in the fresh green biomass of all amaranth species (Amaranthus spp. ).…”

Comparative study of amaranth species (Amaranthus spp.) in the temperate continental climate of Russian FederationAbstract: Field experiments were carried out in the Chuvash Republic, which is located in the center of the European part of Russia on the banks of the Volga River and has a moderately continental climate with warm summers, cold winters, well-defined transitional seasons and average annual rainfall of 500 mm. There are many cultural and wild species of amaranth in nature, differing in morphological and biological features. The objects of research were four common species of amaranth (Amaranthus spp.): A. cruentus L., A. caudatus L., A. hybridus L., A. spinosus L.. Particular attention in the experiment was paid to the morphological and biological characteristics of plants according to the growth stages during growing season and the formation of the yield of green mass and grain during 3 years of research. As a result of the experiment, the possibility of cultivating a heat-loving amaranth culture in the climatic conditions of the Chuvash Republic was proved and adaptive species for growing green mass (A.cruentus and A.caudatus) and for grain (A.cruentus) were identified. Primerjalna raziskava vrst ščira (Amaranthus spp.) v zmernem kontinentalnem podnebju Ruske FederacijeIzvleček: Poljski poskus je bil izveden v Čuvaški republiki, v osrednem delu evropskega dela Rusije, na bregovih Volge, ki ima zmerno kontinentalno podnebje s toplimi poletji, mrzlimi zimami, z dobro izraženimi prehodnimi obdobji in s povprečno letno količino padavin 500 mm. Na območju uspeva več gojenih in podivjanih vrst ščira z različnimi morfološkimi in biološkimi lastnostmi. Predmet raziskave so bile štiri pogoste vrste ščira: A. cruentus L., A. caudatus L., A. hybridus L., A. spinosus L.. Posebna pozornost je bila posvečena morfološkim in biološkim lastnostim rastlin glede na fazo v rastni sezoni, tvorbi biomase in zrnja v 3 letih raziskav. Kot rezultat poskusa je bila dokazana možnost gojitve toploljubnih ščirov v klimatski razmerah Čuvaške republike, za zeleno biomaso vrsti A.cruentus and A.caudatus in za zrnje vrsto A.cruentus.

“…The low availability of Met is in accordance with the previous studies (Montagnac et al., ; Van Hal, ). To compensate this limitation in Anchote, additional consumption of animal or plant proteins such as milk, egg, lentils, and pulses are highly recommended (Andini, Yoshida, & Ohsawa, ).…”

The protein content and amino acid profile of Anchote (Coccinia abyssinica) leaves and tubers were determined from ten different accessions taken from Debre Zeit Agricultural Research Center, Ethiopia. Crude protein content was determined by Kjeldahl method and amino acid profile was analyzed using performic acid oxidation and acid hydrolysis by ninhydrin‐derivatized analysis with amino acid analyzer. Crude protein content of Anchote tuber ranged from 10.70% ± 0.26% to 13.72% ± 0.10%, whereas the crude protein content in leaves were ranged between 30.38 ± 0.01% (“240407‐1”) and 35.42 ± 0.05% (“223109‐1”). Total amino acid content ranged from 45.12 to 62.89 and 67.31 to 75.69 g/100 g protein for tuber and leaf samples, respectively. The mean values of essential, conditionally essential and nonessential amino acids were 37.22 & 36.79%; 28.62 & 24.10%; and 34.16 & 39.11% for tubers and leaves, respectively. Arginine in tubers and glutamic acid in leaves ranked the highest of all amino acids; while the least dominant essential amino acid was methionine in both parts. Among the essential amino acids, leucine was dominant in all accessions tested with values ranged from 3.12 to 5.32 g/100 g protein in tubers and from 5.15 to 5.65 g/100 g protein in leaves. In general, the average amino acid content was higher in the leaves (71.08 g/100 g protein) compared to the tubers (51.11 g/100 g protein). The nutritional quality of Coccinia abyssinica leaves and tubers range as follows: total essential amino acids (TEAA)/ total amino acids (TAA) (37.57 & 36.82%), TEAA/total non‐essential amino acids (TNEAA) ratio (0.60 & 0.58), The predicted protein efficiency ratio (P‐PER) (1.22 & 1.80), Essential amino acid index (EAAI) (35.28 & 53.93%), Predicted biological value (P‐BV) (26.76 & 47.09%), Nutritional index (4.11 & 17.71%), and Amino acid score (73 & 108) for tuber and leaf sample, respectively. A significant variability was observed in protein and amino acid profile among accessions and plant parts, and the leaf part were found to be richer in protein content and associated nutritional quality.

“…In Ethiopia, the use of the species has been reported against skeleton-muscular diseases (Giday et al 2010). Analysis of variation of nutrient content among Amaranthus species showed that A. dubius had a high protein content (Andini et al 2013), vitamin C, calcium, and zinc (Yang and Keding 2009).…”

Diversity and Differential Utilization of Amaranthus spp. along the Urban-Rural Continuum of Southern Benin. Increasing recognition of the importance of traditional vegetables as sources of nutrients, health benefits, and income has raised the need to evaluate and document knowledge of these resources in local communities. Indigenous knowledge is crucial for sustainable utilization of these plant resources, though this might be threatened by urbanization and economic development. We carried out a quantitative ethnobotanical survey to assess the relative importance of amaranth in vegetable production systems of southern Benin and identify the main criteria that determine the choice of this crop by farmers. The diversity, uses, and knowledge of amaranths was investigated to assess how the degree of urbanization affects farmers' knowledge. Our results showed that Amaranthus cruentus is the main cultivated vegetable in the surveyed areas despite its low economic value. Reasons raised by communities were related to the species' popularity, resistance to nematodes, nutritional value, and short cultivation cycle. Wild amaranths include A. dubius, A. blitum, A. spinosus, and A. viridis. Amaranths were mainly used as vegetables and for their nutraceutical properties. Urbanization was found to negatively affect the knowledge and uses of wild species, whereas the knowledge and utilization of cultivated species was quite homogenous along the urban-rural continuum. We discuss strategies to increase knowledge of wild resources in urban settings and therefore reduce loss of genetic resources.Diversité et utilisation des amarantes (Amaranthus spp.) le long du continuum urbain-rural au Sud-Bénin. La reconnaissance croissante de la valeur nutritionnelle des légumes locaux, leurs bienfaits pour la santé et leur contribution au revenu des populations a révélé la nécessité d'évaluer et de documenter les connaissances associées à ces espèces au sein des communautés locales. En effet, les connaissances endogènes considérées comme importantes pour la conservation et l'utilisation des ressources phytogénétiques pourraient être en voie de disparition du fait de l'urbanisation et du développement économique. La présente étude a porté sur une enquête ethnobotanique réalisée le long du continuum urbain-rural au Sud-Bénin afin d'évaluer l'importance relative des amarantes et d'identifier les principaux critères qui déterminent le choix de cette culture par les agriculteurs. En outre, la diversité, les usages et les connaissances des amarantes ont été étudiés afin d'évaluer comment le degré d'urbanisation affecte les connaissances des agriculteurs. Nos résultats ont montré que Amaranthus cruentus est la principale espèce cultivée dans les zones étudiées en dépit de sa faible valeur économique. Les 1 , Bronx, NY 10458-5126 U.S.A. raisons évoquées par les producteurs étaient liées à la popularité de l'espèce, sa résistance aux nématodes, sa valeur nutritionnelle et son cycle de culture court.
