ABSTRACT
This study was conducted during the 2020/2021 dry season at the Crop Science Research Farm in the Faculty of Agriculture, University of Benin, Benin City to determine the effect of cutting height and plant density on the growth and yield of Celosia. The experiment was laid out in a randomized complete block design in three replications consisting of nine treatments; H1D1 (10cm cutting height and plant density 250,000 plants ha-1),H1D2 (10cm cutting height and plant density 160,000 plants ha-1),H1D3 (10cm cutting height and plant density 110,000 plants ha-1),H2D1 15cm (cutting height and plant density 250,000 plants/ha-1),H2D2 (15cm cutting height and plant density 160,000 plants ha-1),H2D3 (15cm cutting height and plant density 110,000 plants ha-1),H3D125cm cutting height and plant density 250,000plants ha-1),H3D2 (25cm cutting height and plant density 160,000 plants ha-1), H3D3 (25cm cutting height and plant density 110,000 plants ha-1).
The parameters measured include plant height (cm), number of leaves, number of branches, stem diameter(cm) and herbage fresh weight (g). The study revealed that cutting height and plant density had significant effect on the vegetative parameters at 3 weeks after transplanting.H2D1 produced the highest number of branches (30.92) which was not significantly different from H3D3 which produced (30.50).The highest herbage yield was produced at 15cm cutting height and plant density 250,000 plants ha-1 (H2D1).
