The study looked at how different plant populations affect the growth and yield of pearl millet in Nigeria. They found that increasing the number of plants per hill led to higher grain and stalk yields. One variety, Sosat-C88, performed better at lower plant populations, while another variety, GB8765, had optimal yields at a higher plant population. Overall, increasing plant population resulted in higher grain and stalk yields for most varieties tested. This research suggests that the best plant population for maximum yield varies depending on the specific variety of pearl millet being grown.
