ONION BULB CONSERVATION: CASE OF AN EXPERIMENTAL STUDY

Storage losses of onion bulbs are enormous, hence the need to contribute to the search for solutions. Our experimental work on the conservation of onion bulbs with the "violet de Galmi" variety took place effectively in the thermal conditions of 24.21 ° C - 27.84 ° C, and hygrometry of 42.65% - 84.81%, in the storage room. The storage checking was done every week. This is a natural convection storage that lasted seven (07) months. At the end, 141.068 kg over 666 kg or 21.18% were lost. It highlighted the rate of rotten bulb contagion among the loss. This work has also highlighted the difficulty of determining the mass lost precisely.
