چکیده انگلیسی
The sensitivity of silage maize to changing climate in Denmark under varying Nitrogen (N) and undersown catch crop (CC) treatments was investigated using a process-based, soil-plant-atmosphere model; Farm Assesment Tool (FASSET), and the impact response surfaces (IRS). The baseline period consisted of an experiment over a 3-year time period from 2009 to 2011 that was carried out in mid Jutland, Denmark (56°5ʹN, 9°56ʹE 38â¯m asl). The results indicated that an increase from the average annual temperature (â6.5â¯Â°C) of up to 1.5â¯Â°C is beneficial for maize yield. At approximately 8â¯Â°C annual average temperature and above, the yield dropped sharply, and any positive impact of varying N treatments and CC was diminished. The maize yield was not as sensitive to precipitation as it was to temperature. The undersown grass in silage maize was not found to be a viable option in relation to warmer climate for all of its benefits were widely overshadowed by the excessive NO3â leaching risk. This study suggested that the warming of the climate along with the projected increase in precipitation in Denmark in the future will greatly challenge the management of N in maize cropping systems. Under changing climate, increasing crop N uptake efficiency by both maize and CC should be targeted as priority. Root growth in this context is an essential feature for the N uptake efficiency. Further research on potential adaptation of different deep-rooted species in the warmer climate that might be suitable as undersown CC is needed.
