1000-grain weight of sorghum

Sorghum bicolor (L.) Moench

An important indicator of grain size and biological quality of sorghum seeds, which is normally about 21 g. It is used to calculate the precise seeding rate and to evaluate the potential productivity of the crops.

In the reference 35 varieties crop Sorghum, where this is mentioned in the description.

For grain sorghum, the established standard minimum 1000-grain weight is 15 g, although typical values are around 21 g. Depending on varietal characteristics and growing conditions, this indicator most often ranges from 16 to 30 g.

This parameter is key for converting the weight-based seeding rate into a quantitative one, which is critically important for controlling plant population density, given the high tillering capacity of the crop. Heavier seeds contain an increased reserve of nutrients, ensuring high growth energy, better competitiveness against weeds, and survival under stressful conditions at the start of the growing season.

The 1000-grain weight is one of the elements of sorghum productivity structure and shows a positive correlation with final yield. A decrease in this indicator is usually caused by unfavorable meteorological factors during the grain-filling period, such as drought or high temperatures, as well as the impact of pests and diseases.
