“…Buckwheat grains and hulls consist of a number of components with pro-health properties and biological activity, i.e. flavonoids and flavones, phenolic acids, condensed tannins, phytosterols and fagopyrins (Vojtíšková et al, 2012;Dziedzic et al, 2015;Klepacka, 2015;Žvikas et al, 2016). Buckwheat groats contain free phenolics (4.5-17.1 mg of gallic acid (GA) equivalent g -1 ).…”

The accumulation of valuable nutrients in grains is dependent on a number of factors, including biotic and abiotic stress, and the effects of herbicides. The aim of this study was to determine the effect of a metazachlor and clomazone mixture and 2-methyl-4-chlorophenoxyacetic acid (MCPA) on the chemical composition of the neutral detergent fibre, lipids, protein and ash content of common buckwheat (Fagopyrum esculentum Moench) seeds. A field experiment was conducted in 2013-2015. The mixture containing metazachlor (750 g ha -1 ) and clomazone (96 g ha -1 ) applied one day after buckwheat sowing proved to be phytotoxic and caused leaf chlorosis. These symptoms persisted until the end of the flowering stage and gradually disappeared during the seed formation stage. MCPA applied at the stage of two true leaves at a dose of 750 g ha -1 showed a higher phytotoxic effect, manifested by deformation and discoloration of the buckwheat stems. MCPA as well as mixture containing metazachlor and clomazone significantly increased the content of neutral detergent fibre (NDF), its fractions (hemicellulose, cellulose and lignin) and proteins compared with the control treatment. However, they caused a significant decrease in the ash content. Compared to the untreated control buckwheat seeds, application of MCPA caused an increase in the content of the following compounds: neutral detergent fibre (1.2%), hemicellulose (0.8%), cellulose (11.1%), lignin (0.6%) and protein (2.03%); mixture metazachlor and clomazone increase: neutral detergent fibre (0.8%), hemicellulose (0.5%), cellulose (11.3%), lignin (0.43%) and protein (0.60%). Each of the surveyed phytotoxic substances caused stress to buckwheat plants, with MCPA applied in the stage of two true leaves at a dose of 750 g ha -1 being the most aggressive stressor that caused deformation of the buckwheat plants, decreased yield (0.68 t ha -1 ) and increased protein content (2.03%) in the buckwheat grains.

Buckwheat (Fagopyrum esculentum Moench) is grown primarily to produce grains for human consumption because of its nutritive and health promoting value. Buckwheat is the sixth staple food after rice, wheat, maize, finger millet and barley in Nepal. This study principally focuses on the mineral nutrient content of buckwheat and their role in human health and nutrition. Buckwheat is used as basic food, animal feed, vegetable, soup, beverage and medicine. It is rich source of proteins, starch, antioxidants, dietary fibre and trace elements. It is rich in minerals like Zn, Cu, Fe, Mn, Se, K, Na, Ca and Mg. It is rich in fats, flavonoid and vitamin especially B groups. Buckwheat proteins contain amino acid which is well balanced and is of a high biological value. Buckwheat is rich source of rutin. The high level of rutin is extracted from the leaves for medicine to treat high blood pressure. This review serves as a useful tool to researchers and nutritionist who are working in food and nutritional security in Nepal.
