Abstract

Thrips infestation was significantly less on onion plants in crop mixtures than on pure crop. Tomato, mint and coriander were significant in lowering thrips population densities on onion in crop mixtures. Tomato had greater influence than coriander and mint. However, in contrast to the pest load, the bulb yield of onion was significantly less in plots where onion was intercropped with tomato.

Keywords: Thrips tabaci, Onion, Crop mixtures.
