How to increase wheat water use efficiency
A healthy, fast-growing crop of wheat, fully supported by fertiliser, makes more efficient use of water to maximize yields.
Fertiliser increases water use efficiency
Yara’s crop nutrient recommendations for wheat help the crop make more productive use of water through encouraging strong growth and high yields leading to more transpiration and less drainage and direct evaporation.
Regular fertiliser use will encourage rooting, ensuring better extraction of water from the soil.
Well-balanced nutrition also maximizes leaf efficiency, providing a strong canopy that reduces soil evaporating by creating shade across the grove for a longer period.
Potassium (via its osmotic function) and nitrogen (as a result of the internal regulation of hormones and xylem pH) are important for efficient and optimal regulation and control of CO2 uptake and water loss through the stomata.
Finally, by using comprehensive, tailored, fertiliser programmes that ensures no nutrient is lacking, yield is increased, thereby producing more fruit for every mm of rainfall or irrigation water that is applied.
Yara recognizes that this improved ‘water use efficiency’ is increasingly important given scarcity of water supply. Indeed, with 2.8 billion people living in regions with insufficient water, the importance of making best use of this limited resource is fundamental to sustainable crop production.

How to maintain wheat green leaf canopy
The key to achieving high wheat yields, having established the correct canopy structure, is to maintain the green area right through to the final grain filling period, capturing as much of the incident light as possible and converting it to yield.
How to increase wheat grain size and weight
Wheat grain size is strongly influenced by plant nutrition particularly during the important grain filling period. Nitrogen, phosphate, potassium, magnesium and zinc are particularly important.
How to increase wheat protein content and quality
Nitrogen and sulphur both influence grain protein content and quality. Nitrogen should be applied when the plant can still incorporate the nitrogen into its grain, and sulphur levels need to be adequate to ensure this does not limit nitrogen use.
How to increase wheat grain specific weight
Grain specific weight is a measure of the density of the grain. Specific weight is predominantly a genetic trait of varieties, but poor crop nutrition and application can reduce specific weight.
