1000-kernel weight of barley

Hordeum vulgare L.

An integral indicator of barley grain plumpness and density, expressed in grams at a standard moisture content of 14%. It is a key factor for calculating seeding rates and estimating the crop's yield potential.

In the reference 323 varieties crop Barley, where this is mentioned in the description.

To determine this indicator, two parallel 500-kernel samples are taken from an average sample of cleaned barley seeds and weighed with an accuracy of 0.01 g. The final 1000-kernel weight value is calculated as the sum of the weights of these two samples.

Barley 1000-kernel weight values are subject to significant varietal and environmental variability. Values below 35 g usually correspond to unfavorable conditions or drought, while 40–45 g are considered a good level. Varieties with a 1000-kernel weight of over 50 g, capable of reaching 59 g, are considered large-seeded.

A high grain weight indicates the accumulation of a large reserve of nutrients, which promotes the formation of vigorous seedlings and increases productivity. The use of this parameter is necessary to transition from a weight-based seeding rate to a quantitative calculation of viable seeds per hectare to ensure optimal plant density.
