Crop water use efficiency
Crop water use efficiency (WUE), or yield per unit of water used, can be improved through irrigation management and methods, including deficit irrigation (irrigating less than is required for maximum yields) and supplemental irrigation (irrigating to supplement precipitation so as to avoid crop failure or severe yield decline). Thus, WUE is key for agricultural production with limited water ...

Where is your soil water? Crop yield has the answer
Crop yield is highly dependent on soil plant-available water, the portion of soil water that can be taken up by plant roots. Quantitative determination of the maximum amount of plant-available water in soil using traditional methods on soil samples remains challenging, especially at the scale of an entire field. However, a map of plant-available water capacity for a field would be instrumental in ...

Despite weather extremes EU-27 cereal production in 2013 expected to be higher than last year
This year total cereal production in the EU-271 is forecast to be well above 2012 levels and above the average of the past five years. This agricultural year has so far been marked by an unusually prolonged winter for western and central Europe and heavy rainfall in May and June. However, the impact of poor weather on crops in some areas of the EU has been offset in other areas; for example, the ...

Fertiliser can offset heat for African farmers
[NAIROBI] African smallholders in dry areas can overcome climate change and even double crop yields if they invest in fertiliser use and harvest rainwater, researchers have found. Farmers in arid and semi-arid areas usually protect themselves from climate-related losses by investing as little as possible in farm inputs such as fertilisers. But in doing so they fail to grab opportunities for ...
