Abstract

A field experiment was conducted to evaluate the response of vegetable sesame to nitrogen and phosphorus fertilisation. The treatments consisted of a factorial combination of three rates each of N ( 0, 50 and 100 kg N ha-1 and P 0, 11, and 22 kg P ha-1). Arranged in a Randomised Complete Block Design with three replicates. The crop showed a positive response to N, and in applications with higher values, growth, vegetative parameters, and yield were optimised at the highest rate of 100 kg N ha-1. The application of 22 kg P ha-1 resulted in taller plants, with a higher number of leaves and branches and heavier dry leaf weight. Combined application of 100 kg N + 22 kg P had the highest values of growth and yield parameters, while those that received neither fertiliser recorded the lowest values for both growth and yield components. Therefore, application of 100 kg N ha-1 resulted in rapid vegetative growth and higher vegetative yield, while the application of 22 kg P ha-1 led to rapid vegetative growth of sesame during the early stages.
