Soil phosphorous enrichment by buckwheat along with its ability to suppress weeds by allelopathic effect

Abstract

Human diet needs to be revolutionized and should start exploring new food habits which are beneficial in multiple ways for both human mankind and ecosystem, starting with the problems faced by human for depending on only specific crops like rice, wheat, maize, are the nutritional deficiencies in the crop and also some health implications like diabetes caused by prolonged consumption of rice, buckwheat has lower Glycemic index compared to rice, we can adapt for cultivation and consumption of buckwheat as an alternative of this crops, for its unique ability of its roots to solubulize soil phosphorous which will not only enhance P content in soil but also help succeeding crop to utilize the solubulized P, for this it’s called as P “ scavenger” crop, which cannot be performed better by other crops as buckwheat does and also for its unique medicinal values with the absence of gluten and the presence of rutin which is obtained from the leaves, plays a key role in preventing rupture of arteries and also the tender shoots are used as leafy vegetables and the flowers also produce good quality honey which will prevent the effect of free radicals which causes cancer, buckwheat is rich in protein lysine, which is deficit in cereal crops, it has dense fibrous root system with deep tap roots which helps in improving soil aeration and to check soil erosion, buckwheat also helps in suppressing the weed growth during its vegetative and flowering stage as its leaves and stem release certain allelochemicals which results in decrease of nitrogen uptake of weeds thus reducing the entire biomass.
