Invasion and control of water hyacinth (Eichhornia crassipes) in China [PDF]

Journal of Zhejiang University SCIENCE B, 2006
By the time of primary 21st century, water hyacinth had become a serious environmental problem in China. Water hyacinth contributes to the major part of ecological hazards from the invasion of foreign plant species, which is estimated about USD 7 billion a year in values. In the past 10 years, herbicides glyphosate, 2,4-D and paraquat have been used in

Rooted macrophytes reduce sediment CH4 storage and net production: An experimental approach using a novel scanning method

Limnology and Oceanography Letters, Volume 11, Issue 1, January 2026.
Abstract Methane (CH4) emissions from freshwater ecosystems are significant but rarely quantified in vegetated zones. We assessed the influence of five macrophyte species that root in the sediment differing in growth form and root biomass on CH4 emissions and sediment gas storage.

Yield of Short Duration Drought Tolerant Transplant Aman Rice Varieties as Influenced by Integrated Nitrogen and Weed Management Practices

Advances in Agriculture, Volume 2026, Issue 1, 2026.
Rice productivity varies substantially across rice varieties along with judicious nitrogenous fertilizer and weed management (WM) practices. At AFL, Bangladesh Agricultural University, we tested two cultivars of short‐duration drought‐tolerant T. aman (autumn) rice, Bangladesh Rice Research Institute (BRRI) dhan66 and BRRI dhan71, and how different ...

Performance of Concrete Using Water Hyacinth Ash as a Partial Cement Substitute

Advances in Materials Science and Engineering, Volume 2026, Issue 1, 2026.
Concrete is one of the most widely used construction materials, with cement as its primary component. However, cement production significantly contributes to CO2 emissions, posing environmental challenges. This study investigates the use of water hyacinth ash (WHA) as a sustainable partial replacement for cement in C‐30 grade concrete.
