Summary

The results are recorded of three field experiments, designed to investigate the effects of plant population and nitrogen fertilizer on growth and yield of maize. High yields of grain can be obtained in Trinidad provided plant populations are at least 20 000 plants per acre, nitrogenous fertilizer is added at the rate of 5–6 cwt per acre, weed and insect pests are controlled, and water is not a limiting factor at any stage of crop growth. Growth analysis has shown the importance of high leaf area indices in the production of high grain yields.
