Title	Effect of Water Hyacinth Green Manuring on Biomass Yield of Spinach and Nutrient Availability

Creator	K.K. Barman, Nasreen Ghazi Ansari and Monika Dubey

Subject	Weed Utilization, Eichornia, Green manure

Description	Not Available Decomposition of water hyacinth (Eichhornia crassipes) and its effect on spinach growth was studied in a Vertisol. It was fully decomposed within 30 days under laboratory condition and increased the available N, P and K content of the soil. No allelopathic effect due to water hyacinth decomposition was noticed on spinach in the field. Application of 120 kg N /ha through urea increased spinach yield by 106%. Application of water hyacinth increased the spinach yield by 85 and 42% when incorporated in the soil in fresh (green) and dry conditions, respectively. Initially mineral N content of the field soil was higher (34.3 mg /kg soil) when N was applied through fresh water hyacinth as compared to 24.7 mg /kg soil with farmyard manure incorporation. It was concluded that water hyacinth could be used as an ex-situ green manure and is better than farmyard manure in terms of increasing the available plant nutrients in soil and dry matter yield of spinach.
