Dynamics of chlorophyll and N concentration on e0 and e3 leaves of maize hybrids in winter in subtropical region Red light absorbance through maize

ABSTRACT National maize productivity is very low in Nepal. Increase of the productivity is only possible through growing high grain yielding single cross hybrid maize cultivar. So, development and evaluation of maize hybrids are principal steps to select high grain yielding and superior hybrid for cultivar. For it, fifteen newly bred single cross hybrids of yellow maize were examined from the standpoint of chlorophyll (chl) dynamics and their effects on grain yield. the kernels more efficiently from the e3 leaf. It is not necessary that maize hybrids must constantly maintain soluble proteins and chl conc during most of early to mid-grain filling duration for high grain yield. Instead, diagnostic decline of the soluble protein and chl conc during early to mid-grain filling also accelerate grain filling phenomena
