Abstract
Summary: The effects of differing degrees of leaf removal was studied in maize at different stages of growth and in varying plant densities. In control (untreated) plants significantly lower grain yield/unit area at the higher density (90000 plants/ha) was associated with greater barrenness, percentage of lodging and time taken for silking. Increase in plant density from 60000 to 90000 plants/ha led to a reduction in length and diameter of the ear and in weight of 1000 grains. Delay in the time of leaf removal from the tasselling stage until 10 days later increased yield, number of ears, ear length, diameter and test weight and decreased percentage of barrenness and lodging.Leaf removal adversely affected yield and yield components (number of ears, percentage of lodging, ear size and test weight of 1000 grains). Complete leaf removal at tasselling time delayed silking and reduced lodging.
