Barley

High barley yields come from achieving the correct ear numbers, maintaining a healthy, green leaf canopy, increasing grain numbers per ear and grain size.

To achieve high barley yields, having established the correct canopy structure, it is important to maintain the green leaf area right through to the final grain filling period, capturing as much of the incident light as possible and converting it to yield

The number of tillers, leaves and shoots determines the size of the canopy and the final ear density at harvest.

Barley grain size is strongly influenced by plant nutrition particularly during the important grain filling period.

The number of grains in each ear of barley depends on the number of fertile spikelets on the central stem of the ear.

Crop nutrition can have a great impact on the quality of the harvested barley and fertiliser applications should be planned to help achieve the highest value for the barley often through a combination of specifications.

Plant nutrients predominantly increase barley yield and quality through ensuring no mineral deficiency is restricting growth and development.

The fundamental agronomic principles behind barley production are to first build an efficient leaf canopy and then keep this photosynthetically active for as long as possible through to harvest.

Correct rate and timing of the application of fertilisers to barley is important to achieve the highest level of nutrient use efficiency which maximises crop productivity whilst minimising any environmental impact

Barley nutrient requirements vary depending on the crop growth stage. Find out which nutrients are most important and the roles of nutrients at different barley growth stages.

The barley crop goes through three distinct phases as it grows from planting to harvest. These phases can be described as foundation, construction and production.

Barley varieties are very diverse and can therefore be classified in several ways. The most used classifications are by ear type, grain use and awn characteristics.
