Agronomy 180 - Assignment 11 - part 1 and 2 | Questions And Answers Latest {2024- 2025}
A+ Graded | 100% Verified
Warmer temperatures can ____ the rate of ____ which could ____ the length of ____ and consequently
____. - Increase, phenological development, decrease, grain fill, reduce yield potential.
Thermal time and chronological time are always the same each day and growing season. - False
In general, which surface energy budget component is greater over a vegetated surface (corn field)
compared to a paved surface (parking lot). - Latent heat flux
The latent heat flux represents the "hidden" energy that goes into evapotranspiration from crop
canopies. - True
Which figure most accurately depicts the surface energy budget over an unstressed, vegetated surface?
- B.
Calculate the growing degree days accumulated for a day and crop with the following characteristics.
Tmax = 15 deg C
Tmin = 0 deg C
Tase = 10 deg C - 0 deg C day
What does the numb rain the names of RCP scenarios represent? - The change in global average
radiative forcing in 2100 relative to the pre-industrial average in [W m^-2]
The term phenology refers tot he development of vegetation. Phenology is typically linked to thermal
time. Different crops have different phenological stages, but can typically be broken down into
vegetative and reproductive stages. Under a warming climate, there will be less time from crops to fill
grains unless we select varieties that have a longer maturity. - True
Fill in the blanks after estimating the number of grain-fill days for each scenario: there are ____ grain-fill
days in scenario one and ____ grain-fill days in scenario two. - 80,60
