Sunflower crop yield prediction by advanced statistical modeling using satellite-derived vegetation indices and crop phenology

Geocarto International, 2023
Timely crop yield information is needed for agricultural land management and food security. We investigated using remote sensing data from the Earth observation mission Sentinel-2 to monitor the crop phenology and predict the crop yield of sunflowers at ...

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Depending on the descriptions of crop yield and social response to crop failure/harvest from Chinese historical documents, we classified the crop yield of North China during 601–900 AD into six categories and quantified each category to be the crop yield

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

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 ...

Calpain small subunit homodimerization is robust and calcium‐independent

FEBS Letters, EarlyView.
Calpains dimerize via penta‐EF‐hand (PEF) domains. Using single‐molecule force spectroscopy, we measured the strength and kinetics of PEF–PEF homodimer binding. The interaction is robust, shows a transient conformational step before dissociation, and remains largely insensitive to Ca2+.
