Stresses from heat and drought are expected to increasingly suppress crop yields, but the degree to which current models can represent these effects is uncertain. Here we evaluate the algorithms that determine impacts of heat and drought stress on maize in 16 major maize models by incorporating these algorithms into a standard model, the Agricultural Production Systems sIMulator (APSIM), and ru...

Cultivar and sowing date selection are major factors in determining the yield potential of any crop region. To explore how climate change affects these choices, this study performed a regional scale analysis using well-validated APSIM-maize model for Northeast China Plain (NEC) which is leading maize (Zea mays L.) producing area China. Results indicated that high temperature had significantly n...

For arable stockless farming systems, the integration of catch crops (CC) during fallow period might be a key for closing nitrogen (N) cycle, reducing N leaching and increasing transfer to subsequent crop. However, despite considerable research efforts, fate in such integrated systems remains unclear. To address this, two-year field experiment was carried out northern Germany with different CC,...

Soil salinity is the main environmental limiting factor for current agricultural farming systems in Bangladesh coastal zone. Targeting crop selection to ameliorate its impact food production a priority ensure security, diversifying outputs and reducing smallholders' vulnerabilities. In this context, growth modelling emerges as useful tool exploring different scenarios selection. Studying spatia...

Declining soil fertility and climatic extremes are among major problems for agricultural production in most dryland agro-ecologies of sub-Saharan Africa. In response, the agroforestry technology intercropping Gliricidia (Gliricidia sepium (Jacq.)) Maize (Zea mays L.) was developed to complement conventional management technologies. However, diversified information on profitability Gliricidia-Ma...

Abstract This paper addresses the acoustic and aerodynamic characteristics of small rotor configurations, including influence rotor–rotor interactions. For this purpose, a Rotor/Rotor/Pylon configuration is chosen for both test numerical simulations. The wind tunnel experiments on various were performed in DLR’s Acoustic Wind Tunnel Braunschweig (AWB). involve isolated rotors, rotors tandem coa...

Irrigated cotton (Gossypium hirsutum L.) growers in the Murray-Darling Basin (MDB) of Australia, are challenged by limited water availability. This modelling-study aimed to determine if deficit irrigation (DI) practices can potentially improve use efficiency (WUE) for furrow (FI), overhead sprinkler (OSI) and subsurface drip (SDI) systems. We validated Agricultural Production System sIMulator (...

Timely information on the onset of rain is essential for effectively adapting to climate variability and increasing resilience rain-fed systems. However, defining optimal sowing dates based has been challenging. We compared analyzed West African Monsoon according Raman's, modified Sivakumar's, Yamada's, Liebmann's definitions using station data from 13 locations in Senegal 1981 2020. Subsequent...

Year to year change in weather poses serious threats agriculture globally, especially developing countries. Global climate models simulate an increase global temperature between 2.9 5.5 °C till 2060, and crop production is highly vulnerable warming trends. Extreme causes a significant reduction yields by negatively regulating the phenology. Therefore, evaluate impact on cotton (Gossypium hirsut...

With global food demand predicted to grow by 50–80% 2050, timely strategies are required best adapt the projected changes in agriculture. In this study, we illustrated how adaptation not requiring additional inputs (sowing date and genotype choice) could be used minimise impact of stresses raise wheat productivity Australia. Yield abiotic impacting crops were quantified silico for 1990s (1976–2...
