Comparing the Relationship of Different Drip Irrigation Uniformity Parameters with Crop Yield [PDF]

Journal of Soil Sciences and Agricultural Engineering, 2020
Drip irrigation system has the ability to apply water over the field uniformly. Uniformity of drip irrigation can be measured through many parameters. Uniformity is one of the procedures which should be considered in drip irrigation design and management

Crop Yield and Temperature Changes in North China during 601–900 AD

Advances in Meteorology, 2014
Depending on the descriptions of crop yield and social response to crop failure/harvest from Chinese historical documents, we classified the crop yield of North China during 601–900 AD into six categories and quantified each category to be the crop yield

An Improved Approach of Winter Wheat Yield Estimation by Jointly Assimilating Remotely Sensed Leaf Area Index and Soil Moisture into the WOFOST Model

Remote Sensing, 2023
The crop model data assimilation approach has been acknowledged as an effective tool for monitoring crop growth and estimating yield. However, the choice of assimilated variables and the mismatch in scale between remotely sensed observations and crop ...

Quantitative trait locus mapping for salt and drought tolerance traits in wheat (Triticum aestivum L.)

BMC Plant Biology
Background Wheat (Triticum aestivum L.) is susceptible to abiotic factors during its growth period, such as salt and drought. The germination stage is the initial growth stage of wheat growth, when wheat is particularly sensitive to salt and drought ...

Observational constraint of process crop models suggests higher risks for global maize yield under climate change

Environmental Research Letters, 2022
Projecting future changes in crop yield usually relies on process-based crop models, but the associated uncertainties (i.e. the range between models) are often high. In this study, a Machine Learning (i.e.

The (Glg)ABCs of cyanobacteria: modelling of glycogen synthesis and functional divergence of glycogen synthases in Synechocystis sp. PCC 6803

FEBS Letters, EarlyView.
We reconstituted Synechocystis glycogen synthesis in vitro from purified enzymes and showed that two GlgA isoenzymes produce glycogen with different architectures: GlgA1 yields denser, highly branched glycogen, whereas GlgA2 synthesizes longer, less‐branched chains.
