Changes in Kernel Quality of a Long-Seasoned Groundnut Arachis Hypogaea L. Variety during Maturation
TL;DRAbstract
In a comparison of 4 techniques for estimating groundnut seed maturity, a method based on testa colour and thickness appeared the best, although one based on light absorbance of the expressed oil appeared to have potential in certain circumstances. In trials at Salisbury and Chiredzi, rapid deterioration in seed quality as well as a decrease in pod number and shelled nut yield occurred at the end of the growing season before seed maturation and mean seed size and weight reached a maximum. Optimum harvesting date, if seed quality was not to be unduly affected, was when seeds were 40-70% mature
