HIGHLIGHTS:

There is variability concerning the physical properties of cowpea genotypes.

This study describes the main physical properties of grains of 11 commercial cultivars and 17 elite lines of cowpea.

The physical properties of grains can interfere with the drying and storage process.

ABSTRACT

The present study aimed to evaluate the physical properties of cowpea genotypes grains. The study was conducted at the Laboratory for Storage and Processing of Grains and Seeds at the North Federal Institute of Minas Gerais (IFNMG) in Januária, MG, Brazil. The treatments were composed of 17 elite lines and 11 cultivars of cowpea. The experimental design was in randomized blocks with four replicates. The properties evaluated were bulk density, angle of repose, 1000-grain weight, shape (sphericity and circularity), size (projected area) of the grains, water content, and porosity of the grain mass. The genotypes give different sizes to cowpea beans, which influences the variation of bulk density, angle of repose, and 1000-grain weight. There was no statistical difference among the cowpea genotypes evaluated for water content and mass porosity.
