Crop simulation models are valuable tools for prediction of crop performance under various weather conditions and allow designing methods to limit the negative impacts of adverse environmental constraints. Agricultural Production Systems sIMulator (APSIM) is a comprehensive model that simulates the performance of a wide range of crops in response to climatic, soil and management factors. In thi...

The sustainable development of efficient water-saving agricultural irrigation in Loess Plateau requires reasonable and quantitative planning, design, management, and strategies based on crop-water-salt response relationship. In the present paper, data were measured by using the soil-water-salt sensor CS655 to modify the simulation of root uptake in the original Soil Water Atmosphere Plant (SWAP...

Modelling crop evapotranspiration (ET) response to different planting scenarios in an irrigation district plays a significant role in optimizing crop planting patterns, resolving agricultural water scarcity and facilitating the sustainable use of water resources. In this study, the SWAT model was improved by transforming the evapotranspiration module. Then, the improved model was applied in Qin...

Regional climate models (RCMs) are considered to be more useful than general circulation models for assessing impacts of climate change scenarios in agriculture. In this communication, the climatic outputs of an RCM–PRECIS (providing regional climates for impact studies) model were analysed by comparing its baseline simulation daily weather data on temperature and precipitation patterns with th...

In this paper, an intelligent control of the greenhouse in the Greenhouse Management Framework (GMF) has been designed for the purpose of increasing the farmer’s profit and promoting the ease of agricultural production. The GMF is divided into Greenhouse Control Engine and Crop Growth Engine. The Greenhouse Control Engine consists of Data Aggregator, Greenhouse Information Storage, and Greenhou...

Climate change can have significant impacts on agriculture, both in terms of crop production and livestock management. Rising temperatures, changing rainfall patterns, extreme weather events such as droughts floods reduce yields. GCMs been used to predict climate scenarios many cases using the downscaling approach. Crop simulation models are crucial gaining valuable insights into intricate inte...
