Spatiotemporal Estimation of the Olive and Vine Cultivations’ Growing Degree Days in the Balkans Region [PDF]
Atmosphere, 2021 Olive and vine cultivations are two of the most important crops in Europe, yielding high quality and value food products. The climate change over the Balkans may elevate the agroecological pressure for the established crops and shift their cultivations areas. One of the widely-used agroclimatic indices is the growing degree days (GDD) which accumulates

GROWING DEGREE DAYS AS A METHOD FOR DETERMINING CARROT SEED HARVEST [PDF]
HortScience, 1990 Carrot (Daucus carota) L.) seed quality is affected by the environment in which it matures. Substantial differences in germination from year to year and from field to field have been recognized for many years for umbelliferae seed. Part of the explanation for low germination appears to be the harvest of immature seed.

Hedging irrigated maize crop yields using temperature derivatives in Malawi
HeliyonAgriculture production yield varies with weather changes. This causes farmers incur loses. For instance, extreme temperature leads to low maize yield. This study describes incomplete temperature weather derivatives in agriculture markets and applies risk

No Evidence of Excessive Leaf Production by Strawberries Grown in the Subtropics
Agriculture, 2019 Fruit growth in most plants is strongly dependent on photosynthates produced in the leaves. However, if there are too many leaves, the lower part of the canopy becomes heavily shaded and yields are reduced.

Comparison of phenology models for predicting the onset of growing season over the Northern Hemisphere. [PDF]
PLoS ONE, 2014 Vegetation phenology models are important for examining the impact of climate change on the length of the growing season and carbon cycles in terrestrial ecosystems. However, large uncertainties in present phenology models make accurate assessment of the

Projecting Future Change in Growing Degree Days for Winter Wheat [PDF]
Agriculture, 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 archive, two of the best performing Global Climate Models (GCMs) for the region (MIROC5 and CCSM4) to

VEGETATIVE DEVELOPMENT AND GROWING DEGREE-DAYS OF TROPICAL AND WINTER FORAGES [PDF]
Engenharia Agrícola, 2019 ABSTRACT One of the limitations to producing irrigated forages is setting suitable biometric parameters to establish the entrance of animals to grazing areas. Such parameters can be measured or even estimated. Estimates are advantageous for being practical and able to be used for grazing optimization.

Procrastination in the Workplace: Evidence from the U.S. Patent Office [PDF]
, 2016 Despite much theoretical attention to the concept of procrastination and much exploration of this phenomenon in laboratory settings, there remain few empirical investigations into the practice of procrastination in real world contexts, especially in the ...
