The conversion of water hyacinth into biochar offers a sustainable solution to mitigate its proliferation and enhances its potential as a soil amendment for agriculture. This study examined the physicochemical properties of water hyacinth biochar (WHBC) and its impact on soil fertility. Water hyacinth (Eichhornia crassipes) was pyrolyzed at 300 °C for 40 minute with restricted airflow (2-3 m/s), producing biochar with desirable properties and a yield of 44.

Article Synopsis
  • The study investigated the best nitrogen (N) fertilizer rate and planting density for the upland rice variety NERICA_4 in the Fogera Plain to maximize rice yield and agronomic performance.
  • Conducted over two years (2020-2021), it tested nine varying plant densities and two N rates using a crop simulation model to analyze the effects on yield and biomass.
  • Results indicated a 23% increase in grain yield at a fertilizer rate of 138 kg N/ha and a planting density of 87 plants per m, establishing these parameters as optimal for rice production in the region.*

Maize is one of the most important cereal crops in Ethiopia. However, its yield is lower than its potential mainly due to low soil fertility problems. Therefore, this field experiment was conducted during 2021 main rainy season with the objective of improving maize production through application of brewery sludge and blended NPS fertilizers in North Mecha district, Northwestern Ethiopia.
