Abstract
A two-year study on the effects of planting pattern, plant population and rate of nitrogen (N) application, on tomato cvs.UC 97–3, indicated that yields can be increased considerably and quality can be improved by appropriate nitrogen application and plant population, but not by planting pattern.
Maximum yields were achieved at 120 kg N/acre associated with a plant population of 36 000 plants/acre.
Lower nitrogen rates and/or low plant population significantly reduced yields, while higher rates did not increase yield significantly.
The efficiency of N rates to increase tomato yield decreased with reducing plant populations.
Fruit quality was significantly affected by N rates but not by either planting patterns or population density.
