Upland Rice and Allelopathy

Upland rice (Oryza sativa L.) is mainly grown in Asia, Africa and Latin America. Yield potential of upland rice is quite low and invariably this crop is subjected to many environmental stresses. Further, when upland rice is grown in monoculture for more than two to three years on the same land, allelopathy or autotoxicity is frequently reported. Allelopathy involves complex plant and plant chem...

Analyzing Ecohydrology of Subirrigated Meadow, Dry Valley and Upland Dune Ecosystems Using Remote Sensing and In-situ Estimations in the Semiarid Sand Hills Region of Nebraska, Usa

Water consumed through evapotranspiration (ET) impacts local and regional hydrologic regimes on various spatial and temporal scales. Estimating ET in the Great Plains is a prerequisite for effective regional water resource management of the Ogallala (High Plains) Aquifer, which supplies vital water resources in the form of irrigation for extensive agricultural production. The Sand Hills region ...

Upland Erosion Modeling

Significant advances in upland erosion modeling have been achieved in the past decade. The TREX (Two-dimensional Runoff, Erosion, and Export) watershed model has been developed at Colorado State University for the simulation of surface runoff from spatially and temporally distributed rainstorms on watersheds. The model has been applied in several countries with different climatic conditions. TR...

Darwin’s meadow revisited

One hundred and fifty years since Charles Darwin first collected and surveyed the wildflowers and meadows of his family home, Down House — just 25 kilometres south of London — scientists from the Natural History Museum and conservationists from English Heritage have begun to retrace Darwin's footsteps by replicating his meticulous observations. In 1855 Darwin recorded 142 different plants in Gr...
