Description

It's no great secret that corn hybrids vary for the length of growi.ng season required to successfully grow, develop, and mature. We talk about 'early' and 'late' corns as well as 'short' and 'full' season corns. We also talk about 'days to maturity', as in '112' day corn or '102' day corn. Why all the interest in wanting to accurately distinguish among hybrid maturities?
