Frost Damage Index: The Antipode of Growing Degree Days [PDF]

open access: yesPlant Phenomics, 2023
Abiotic stresses such as heat and frost limit plant growth and productivity. Image-based field phenotyping methods allow quantifying not only plant growth but also plant senescence.

Projecting Future Change in Growing Degree Days for Winter Wheat [PDF]

open access: yesAgriculture, 2016
Southwest Oklahoma is one of the most productive regions in the Great Plains (USA) where winter wheat is produced. To assess the effect of climate change on the growing degree days (GDD) available for winter wheat production, we selected from the CMIP5 ...

Degree Days: Heating, Cooling, and Growing

open access: yesEDIS, 2007
ABE-381, a 7-page illustrated fact sheet by Clyde W. Fraisse, John Bellow, and Charles Brown, discusses how growers can use the AgClimate Web site to find out how to predict Growing Degree Day accumulation for the current season, and to review GDD for ...

Degree-Days: Growing, Heating, and Cooling

open access: yesEDIS, 2018
How much and when it rains, freezes, and thaws can make the difference between boom and bust for a year's crop. However, temperature can predict more than boom or bust. Atmospheric temperature can predict the growth rates of many plants. For this reason,

Growing Degree Day Targets for Fruit Development of Australian Mango Cultivars

open access: yesHorticulturae, 2023
A forward estimate of mango (Mangifera indica L.) harvest timing is required for farm management (e.g., for organization of harvest labour and marketing).

Quinoa Phenological Development Modeling Based on Field Data [PDF]

open access: yesپژوهشهای زراعی ایران, 2023
IntroductionClimate change is rapidly degrading the conditions of crop production. For instance, increasing salinization and aridity is forecasted to increase in most parts of the world. As a consequence, new stress-tolerant species and genotypes must be

Increasing maize yields in Northeast China are more closely associated with changes in crop timing than with climate warming

open access: yesEnvironmental Research Letters, 2021
An understanding of mechanisms that underlie the steady increase in crop yields over recent decades is important for promotion of future sustainable yield gains and maintenance of future food security.

Model Development of the Phenological Cycle from Flower to Fruit of Strawberries (Fragaria × ananassa)

open access: yesAgronomy, 2023
Strawberries are a very important economic crop; thus, a lot of research has been conducted on several production areas. However, phenological performance is still lacking information, especially when it comes to modeling.

Estimating stocking weights for Atlantic salmon to grow to market size at novel aquaculture sites with extreme temperatures

open access: yesFrontiers in Marine Science, 2023
Land-based hatcheries are now capable of growing large Atlantic salmon (Salmo salar) post-smolts (approximately 150 – 1000 g), which means that marine net-pens can be stocked with substantially larger fish compared to traditional stocking sizes (< 150

Thermal Time as a Parameter to Determine Optimal Defoliation Frequency of Perennial Ryegrass (Lolium perenne L.) and Pasture Brome (Bromus valdivianus Phil.)

open access: yesAgronomy, 2020
The herbage mass and nutritional value of harvested forage are fundamental determinants of the production potential of pastoral systems. The objective of this study was to evaluate the growth dynamics and accumulated herbage mass expressed in dry matter (
