Geometric properties of groundnut kernels

Abstract

The length, width, thickness or diameter of kernels of four Bangladeshi groundnut {Arachis hypogaea) varieties viz. Basanti, Maischar, Jhinga and Tridana were evaluated and found to be different. Kernels of each variety were classified small, medium and large on the basis of length and diameter. Kernel shapes of all varieties were prolate spheroids. The surface area and volume of kernels were determined by different formulae and compared with the measured values. Different formulae were found valid for different varieties but not for all the varieties. These findings can provide the information that could be helpful for development of new processing machines or modification and adaptation of the available standard processing machines for the selected groundnut varieties.
