yield potential of grain maize in humid tropical Malaysia

C. K. Lee

Abstract

Grain yields of maize were estimated from replicated cultivar and 0.4 -hectare plot bulk yield trials. Depending on locations. replicated cultivar and 0..1 -hectare plot yield estimates ranged from 3-6 and 3-4 t/ha respectively. With good management and supplementary irrigation. the yield recorded in the bulk yield assessment could be duplicated at farm level while the yield achieved in the replicated yield trials may be taken as the ceiling yield potential.
