The present investigation entitled “effect of withholding irrigation and different harvesting times on post-harvest quality of garlic (Allium sativum L.) during 240 days of storage” was carried out at Research Farm of Department of Vegetable Science and in Post-harvest Laboratory of the Department of Horticulture, CCS Haryana Agricultural University, Hisar, Haryana in 2013-2014. Five levels of withholding irrigation, i.e., 35, 28, 21, 14 and 7 days before harvesting and five levels of harvesting time viz., 150, 157, 164, 171 and 178 days after planting were applied. The Randomized Block Design was used for field studies and Completely Randomized Design for laboratory studies with four replications. The influence of these treatments were recorded on quality parameters viz., total soluble solids and sulphur content in garlic at 30 days interval. Results revealed that both quality parameters increased with the decrease in days to withholding irrigation and with delay in harvesting up to 171 days after planting. Both quality parameters were found maximum with treatments where irrigation was withheld 7 days before harvesting and in treatment where harvesting was done 171 days after planting. Regarding storage period, both TSS and sulphur content increased during earlier part of the storage, i.e., from beginning to 150 days of storage, but thereafter, it decreased up to the end of storage (240 days).
