Abstract: In order to learn the effect of farmyard manure on Chinese water chestnut (Eleocharis dulcis), we assessed the yield, quality and taste of the elite cultivar“Taiqi 1”on different sources of farmyard manure and the chemical fertilizer. Sources of farmyard manure included rapeseed meal, quail dung compost, sheep dung compost,cow dung compost and swine dung compost. The chemical fertilizer was used as control. Results showed that all the farmyard manures significantly improved yield of water chestnut. However, the effects of different farmyard manure were significantly different on the quality and tastes of water chestnut. Rapeseed meal, quail dung compost and sheep dung compost were effective to improve the quality of water chestnut but cow dung compost were not effective. Negative effects on quality of water chestnut were from swine dung compost, which bring water chestnut light salty taste. Moreover, water chestnuts from the swine dung compost tasted hard and waterless. Terminal buds were longer as well. Seed coat was darker. These negative effects caused bad quality of water chestnut and resulted in 33% of price decrease in market. Farmers should avoid swine dung compost in water chestnut growing.
