Physical characterization of morphologically diverse colour maize (Zea mays) seeds

The manual seeding, harvesting and processing operations are the most labour intensive and the current practices have many drawbacks. The physical properties of seeds play an important role for designing or fabricating toolsor devices which are meant for various crop management operations. Therefore, the physical properties of the maize seeds such as mass, geometric mean of diameter, arithmetic mean of diameter, sphericity and projected areas of length, width and thickness were studied at Central Institute for Research on Cotton Technology, Mumbai, Maharashtra and ICAR-Indian Institute of Maize Research, Ludhiana, Punjab during 2021–22 for the futuristic development of many tools for promising lines of colour maize germplasm.
