Ongoing climate change is already affecting crop production patterns worldwide. Our aim was to investigate how increasing temperature and CO 2 as well changes in precipitation could affect potential yields for different historical pedoclimatic conditions at high latitudes (i.e., >55°). The APSIM model used simulate the productivity of four annual crops (barley, forage maize, oats, spring...
سابقه هدف: تغییر اقلیم به طور مستقیم می‌تواند بر امنیت غذایی در نقاط مختلف جهان تأثیرگذار باشد، زیرا فرآیندهای تغییر اقلیم که شامل افزایش غلظت دی اکسید کربن اتمسفری، دما و متغیر بودن بارش است، به‌طور مستقیم محصولات کشاورزی را تحت تأثیر قرار می-دهد. ذرت از جمله گیاهان C4 است که نسبت به تغییرات اقلیمی حساس می‌باشد. بنابراین برای مقابله و کاهش حساسیت ذرت در مواجه با تغییرات اقلیمی نیازمند به کار ب...
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...
Agriculture of the inland arid region in Xinjiang depends on irrigation, which forms oasis of Northwest China. The production and water use of wheat, a dominant crop there, is significantly affected by undergoing climate variability and change. The objective of this study is to quantify interannual variability of wheat yield and water use from 1955 to 2006. The farming systems model APSIM (Agri...
در این مطالعه کارآیی دو مدل گیاهی aquacrop و apsim در شبیه سازی کم آبیاری گیاهان گندم و یونجه مورد بررسی قرار گرفت. داده های مورد لزوم از داده های آزمایش مزرعه ای جمع آوری شد. آزمایش گندم به صورت طرح آماری کرت های خرد شده در قالب بلوک های کامل تصادفی با 3 تیمار آبیاری (100، 80 و 60 درصد نیاز آبی گیاه) و در سه تکرار در منطقه کبوترآباد اصفهان انجام شده بود. آزمایش یونجه در قالب طرح کرت های خرد شد...
Agroforestry is a promising adaptation measure for climate change, especially low external inputs smallholder maize farming systems. However, due to its long-term nature and heterogeneity across farms landscapes, it difficult quantitatively evaluate contribution in building the resilience of systems change over large areas. In this study, we developed an approach simulate emulate shading, micro...
In both Australia and Swaziland large areas of sugarcane rely on irrigation to produce a viable crop or to improve rainfed productivity. Matching water supply to crop demand is essential for productivity and sustainability in any irrigation scheme. Historically Class-A pan evaporation was used as a basis for determining sugarcane water demand or evapotranspiration (ETc). ETc is now frequently o...
Climate change and variability threaten the sustainability of future food production, especially in semi-arid regions where water resources are limited irrigated agriculture is widespread. Increasing temperatures will exacerbate evaporative losses increase plant needs. In this regard, higher irrigation intensities have been posited as a solution to mitigate climate impacts these regions. Here, ...
Maize (Zea mays L.) is a host to numerous pathogenic species that impose serious diseases to its ear and foliage, negatively affecting the yield and the quality of the maize crop. A considerable amount of research has been carried out to elucidate mechanisms of maize-pathogen interactions with a major goal to identify defense-associated proteins. In this review, we summarize interactions of mai...
