The growth status of winter wheat in irrigated field and rainfed field are obviously different and the field types may have an effect on the predictive accuracy of hyperspectral model. The objectives of the present study were to understand the difference of spectral sensitive wavelengths for leaf area index (LAI) in two field types and realize its hyperspectral prediction. In study, a total of ...

Abstract Heat and water stress can drastically reduce crop yields, particularly when they co-occur, but their combined effects the mitigating potential of irrigation have not been simultaneously assessed at regional scale. We quantified temperature precipitation on county-level maize soybean yields from irrigated rainfed cropping in USA 1970–2010, estimated yield changes due to expected future ...

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 ...
