| Abstract: | Seventeen accessions of winged bean germplasm Psophocarpus tetragonolobus (Linnaeus) de Candolle] used as green manure were detected in terms of content of nutrient elements N, P, K, Ca, Mg, S, Fe, B, Mn, Cu, Zn, Mo, Cd, Cr, Hg, Pb and As. The result showed that the winged bean was a high quality green manure containing high N, P and K and fairly high meso-and micro-elements but low heavy metals. According to comprehensive evaluation, these 17 accessions of winged bean germplasm were evaluated comprehensively and categorized into the second or third class of organic manures. |
