These modules include a diverse range of crops, pastures and trees, soil processes including water balance, N and P transformations, soil pH, erosion and a full range of management controls.

From its inception twenty years ago, APSIM has evolved into a framework containing many of the key models required to explore changes in agricultural landscapes with capability ranging from simulation of gene expression through to multi-field farms and beyond.ДЄPSIM is structured around plant, soil and management modules. It is also being used to explore options and solutions for the food security, climate change adaptation and mitigation and carbon trading problem domains.

Decision support systems should be promoted within farming communities to better manage risks associated with on-farm decision making.The Agricultural Production Systems sIMulator (APSIM) was developed to simulate biophysical processes in agricultural systems, particularly as it relates to the economic and ecological outcomes of management practices in the face of climate risk. Future studies on intercropping should consider root interactions and possibly different plant populations and planting geometry as factors that might influence resource capture and use. Dynamic agronomic management practices should be adapted to further increase the systemвЂ™s resilience to predicted climatic uncertainties. As such, it that can be used by farmers located in semi-arid and arid regions as an adaptation strategy for increased productivity. It was concluded that intercropping results in improved productivity, especially under waterвЂ“limited conditions. Scenario analyses using APSIM showed that the development of best management practices should be agroвЂ“ecology specific to ensure dynamic climate change adaptation strategies and increase resilience. The APSIM model was simulated growth, yield and WU of an intercrop system under varying water regimes satisfactorily. Improved water capture and use also increased WUE (50.68%) and RUE (8.96%). This was mainly achieved through facilitative interaction within the intercrop systems which allowed for greater eco-physiological adaptation resulting in improved water capture and use. The field trials established that sorghum yields were stable across different water regimes. The review showcased the potential of bottle gourd as a versatile food crop. The review showed that aboveground interactions within intercrop systems have thoroughly been investigated while belowground interactions were mostly limited. The validated model was then used to develop best management practices for intercropping. Growth, yield and water use (ET) of the sorghumвЂ“cowpea intercrop system were simulated using APSIM. Land equivalent ratio (LER) was used to evaluate intercrop productivity. Extinction coefficient, intercepted photosynthetic active radiation (IPAR) and radiation use efficiency (RUE) for biomass and grain were also determined. Yield and yield components, water use (WU) and WUE were calculated at harvest. Data collected included soil water content, plant height/vine length, leaf number, tillering/branching, leaf area index, relative leaf water content, stomatal conductance and chlorophyll content index as well as biomass accumulation and partitioning. Intercrop combinations considered were sole sorghum, cowpea and bottle gourd as well as intercrops of sorghumвЂ“cowpea and sorghumвЂ“bottle gourd. Field trials were conducted at the University of KwaZuluвЂ“NatalвЂ™s, Ukulinga Research Farm over two seasons (2013//15) under varying water regimes.

This was achieved through a series of studies which included conducting critical literature reviews, quantifying water use and water use efficiency of sorghum-cowpea-bottle gourd, and modelling such systems using Agricultural Production Systems Simulator (APSIM). The aim of the study was to assess the feasibility of a sorghum-cowpea-bottle gourd intercrop systems with a view to determine the resource use efficiencies.

Under these conditions, it is necessary to adopt cropping systems that have a potential to improve productivity.
