Drought and crop yield [PDF]

open access: yesPlant Biology, 2021
AbstractEpisodes of water shortage occur in most agricultural regions of the world. Their durations and intensities increase, and their seasonal timing alters with changing climate. During the ontogenic cycle of crop plants, each development stage, such as seed germination, seedling establishment, vegetative root and shoot growth, flowering ...

High-yield production of graphene by liquid-phase exfoliation of graphite. [PDF]

open access: yesNature Nanotechnology, 2008
Fully exploiting the properties of graphene will require a method for the mass production of this remarkable material. Two main routes are possible: large-scale growth or large-scale exfoliation.

Crop Yield Prediction Using Deep Neural Networks [PDF]

open access: yesFrontiers in Plant Science, 2019
Crop yield is a highly complex trait determined by multiple factors such as genotype, environment, and their interactions. Accurate yield prediction requires fundamental understanding of the functional relationship between yield and these interactive ...

A CNN-RNN Framework for Crop Yield Prediction [PDF]

open access: yesFrontiers in Plant Science, 2019
Crop yield prediction is extremely challenging due to its dependence on multiple factors such as crop genotype, environmental factors, management practices, and their interactions.

Agricultural diversification promotes multiple ecosystem services without compromising yield

open access: yesScience Advances, 2020
Diversification practices benefit biodiversity, pollination, pest control, nutrient cycling, soil fertility, and water regulation. Enhancing biodiversity in cropping systems is suggested to promote ecosystem services, thereby reducing dependency on ...

Drought can favour the growth of small in relation to tall trees in mature stands of Norway spruce and European beech

open access: yesForest Ecosystems, 2018
Background Climate change triggered many studies showing that trends and events of environmental conditions can reduce but also accelerate growth at the stand and individual tree level.

GRAIN YIELD AND YIELD COMPONENTS OF WINTER BARLEY [PDF]

open access: yesThe Journal "Agriculture and Forestry", 2017
The interaction of genotype x environment on yield and 1000 grain weight and test weight at four KG cultivars of barley (Rekord, Jagodinac, Maksa and Grand) was researched in this paper. The experiment was established on the experimental field of the Small Grains Center in Kragujevac (Serbia) during two growing seasons.

Relationships between substrate, surface characteristics, and vegetation in an initial ecosystem [PDF]

open access: yesBiogeosciences, 2013
We investigated surface and vegetation dynamics in the artificial initial ecosystem "Chicken Creek" (Lusatia, Germany) in the years 2006–2011 across a wide spectrum of empirical data.
