Organic Postharvest Technology for Onions

Abstract

The study was conducted in Pudoc Centro, San Vicente, Ilocos Sur to determine the efficiency of the methods used in preserving dried onions and to compare the treatments used in the post harvest of dried onions. T, dried onions were hung and air dried, T- dried onions were hung above an ear then native stove, and T;  dried onions were applied with ashes covered with rice hay. Australian dried onions were used in the experiment. Treatments were laid out following the Randomized Complete Block Design (RCBD) with three replications. Results of the study showed highly significant differences in the survival rate of the dif erent methods used in preserving dried onions. T or "smoked" onions gave the highest computed mean weight of19.5 kg and a survival rate of 97%. This was followed by T (application ofash with hay) with the computed mean of 18.4 kg. and a survival rate of92%.T, (air drying) gave the least with a computed mean of 16.5 kg and a survival rate of 82%, respectively. Iis only fitting and proper that in preserving onions they should be kept in a place wherein smoke is utilized to remove the remaining moisture content of the bulbs.
