Abstract

In field trials during 1977-9, maize was grown under shade conditions at various stages of development. Grain yield was correlated with irradiance received during grain filling and was increased by 10 kg/ha for every MJ/m2 at full light intensity when density was not limiting. In vitro OM digestibility and cell wall content decreased with shading during the latter part of the growing season. Shading also altered ensiling qualities. A hypothesis is formulated to account for the effect of shading on ear size, ear growth and leaf longevity in terms of the prompt effects of shading on root activity.
