Dissecting the genetic basis of fruiting efficiency for genetic enhancement of harvest index, grain number, and yield in wheat

BMC Plant Biology
Background Grain number (GN) is one of the key yield contributing factors in modern wheat (Triticum aestivum) varieties. Fruiting efficiency (FE) is a key trait for increasing GN by making more spike assimilates available to reproductive structures ...

News Sentiment and Commodity Futures Investing

Journal of Futures Markets, EarlyView.
ABSTRACT We investigate the role of media news sentiment in commodity futures investing. The weekly rebalanced long‐short portfolio sorted by news sentiment generates a significant average annualized return of around 8.3% after transaction costs. The time‐series spanning test reveals that the abnormal return of the long‐short portfolio sorted by news ...

Deficit Irrigation and Soil Amendment as Drought Adaptation Strategies: Water Use Efficiency in Pot Experiments With Wheat

Irrigation and Drainage, EarlyView.
ABSTRACT Amidst climate change and recurring droughts, increasing irrigation water amount and frequency alone is not a definitive solution to address water scarcity in agricultural crop production, particularly in soils with poor water retention capacity. This study evaluated the effects of two drought adaptation strategies (deficit irrigation and soil

Evaluation of fall‐seeded cover crops for grassland nesting waterfowl in eastern South Dakota

Wildlife Society Bulletin, EarlyView., 2023
Cover crops are experiencing a revival among Midwestern farmers, and we assessed their attractiveness and safety for nesting ducks in South Dakota. Nest success was markedly lower in cover crops than in perennial cover during both years of our study, including 2019 which was a best‐case scenario for cover crops, with extremely wet conditions delaying ...

Modelling the Impact of Drained and Undrained Conditions on GHG Emissions in Croplands: A Case Study in Lincolnshire, UK

Irrigation and Drainage, EarlyView.
ABSTRACT Agricultural drainage plays a crucial role in land management and crop productivity but significantly impacts greenhouse gas (GHG) emissions. This study examines the effects of drained and undrained soil conditions on GHG emissions in croplands via a case study in Lincolnshire, United Kingdom.
