Unlike the Central and Eastern U.S. Corn Belt where maize is grown almost entirely under rainfed conditions, maize in the Western Corn Belt is produced under both irrigated (3.2 million ha) and rainfed maize (4.1 million ha) conditions. Simulation modelling, regression, and boundary-function analysis were used to assess constraints to maize productivity in the Western Corn Belt. Aboveground bio...

Daily rainfall and evaporation data of 30 years (1969-1998) are analysed for prediction of hydrological events, such as occurrence of effective monsoon (EM) and withdrawal of monsoon (WM), for planning rainfed rice in Eastern India. Those hydrological events are treated with normal (ND), lognormal (LND), Pearson type 111 (PTD), and log-Pearson type 111 (LPTD) distributions. The historical data ...

introduction climate change generally affect all economic sectors, but the agricultural sector is the most sensitive and vulnerable sector, because crops are highly dependent on climatic resource. according to the scientific evidences, climate change in the future, especially the combined effects of rising temperatures and rising co2 concentrations in the atmosphere and increase the likelihood ...

The evaluation of the role different agronomic strategies in achieving sustainable wheat yields under variable Mediterranean climate conditions may involve use resource-use indicators that combine productivity and environmental impact. A two-seasons field experiment was conducted South Portugal to study effect water regimes nitrogen fertilization on yield, grain quality evaluated with footprint...

Ideotypic characteristics of durum wheat associated with higher yield under different water and temperature regimes were studied Mediterranean conditions. Six semi-dwarf cultivars contrasting agronomic performance grown during two consecutive years winter-planted rainfed support-irrigation conditions a late-planting trial support irrigation, at the INIA station Colmenar de Oreja (Madrid). Diffe...
