An experiment was conducted during 1999-2001 in Oltenia, Romania, to determine the effect of plant density (40 000, 50 000 and 60 000/ha) and moisture conditions (irrigated and unirrigated) on the total chlorophyll content of maize hybrids F322, F376, Olt and Cocor. The irrigated plants, particularly F376, had the highest total chlorophyll content. The best results for drought tolerance and total chlorophyll content combined were given by F322 (unirrigated). The optimal density for the highest values of total chlorophyll in irrigated plants was between 50 000 and 60 000 plants per ha. In unirrigated plants, the maximum total chlorophyll was recorded for a density of 50 000 plants per ha. It was also observed that a density of 60 000 plants per ha caused a more intense shadowing of neighbouring plants, resulting in low photosynthetic absorption.
