Effect of different types of mulch on bulb yield of shallot

Abstract

The possibility of using different types of mulch to improve the bulb yield of shallot (Allium cepa var aggregatum) is observed in this paper. The field experiment compared five different types of mulches, including silver, black, straw, screen nylon, and clear plastic mulches, with a non-mulch as a control treatment. Straw mulch and screen nylon mulch reduced shallot biomass but did not significantly affect bulb yield than the control treatment. At the same time, clear plastic mulch increased fresh bulb yield significantly by 30% from 10.26 t ha-1 to 13.29 t ha-1
