Effect of Plant Population Density on Growth and Development of Maize (Zea mays L.) in Ibadan, Southwestern Nigeria
Abstract
The effect of plant population density on growth experiment was carried out in 1992 during the first maize growing season (June - Sept.) inIbadan,Nigeria(7o24' 3o48'E). The row spacing was 60cm for all the three treatments and the interrow spacing was 75, 90 and 120 to give three different plant population densities of 88,888 pl/ha, 74,074 pl/ha and 55,555 pl/ha with one plant per stand with 20% and 33.3% incremental rate between plant population densities.
All the three growth parameters measured recorded no significant differences aming the three plants population densities (88,000, 72,000 and 55,000 plants/ha) throughout the period of the experiment. Although the highest and medium plant population densities (88,000 and 74,000 plants/ha) had higher values than the lowest plant population density (55,000 plants/ha).
