Towards promoting sustainable agriculture and economic growth, the development of the agricultural workforce and set up of innovative agricultural systems are required. Agricultural educational repositories are systems used for storing, reusing and sharing agricultural learning resources. They contribute to agricultural education at different educational levels and target groups. Thus, this pap...
Shrinking arable land due to soil salinization and, depleting fresh water resources pose serious worldwide constraints to crop productivity. A vision of using plant feedstock for biofuel production can only be realized if we can identify alternate species that can be grown on saline soils and therefore, would not compete for the resources required for conventional agriculture. Halophytes have r...

Intergovernmental Panel on Climate Change (IPCC) reported that the global mean temperature had risen for the 20th century at the rate of 0.74oC per 100 years due to increasing green house gas. Climate change such as temperature, precipitation and tropical cyclone activity has been strongly related to agricultural production, water resource, and species diversity. Recent climate change has alrea...
Available water resources for agricultural irrigation have decreased worldwide in recent decades, prompting advances in water saving methods. In this study, soil water regime and water balance in a transplanted rice field with reduced irrigation (multiple shallow depth irrigations) in the Taihu Lake Basin of East China were observed and then evaluated using Hydrus-1D model during two consecutiv...
