Preharvest furrow and drip irrigation schedule effects on postharvest muskmelon quality.

ABSTRACT

A 2-year study was conducted on the effects of furrow or drip irrigation applied 1, 2 or 4 days prior to harvest (following all plots having been watered 8 days prior to harvest) on the postharvest quality of muskmelon fruits (cv. Magnum 45) growing in Arizona. Fruit firmness was not affected by irrigation method or application time. Regardless of irrigation method, water applied 4 days prior to harvest produced fruits with significantly lower soluble solids concentrations (10.8% vs. 12.2% SSC), greater volume (1684 vs. 1508 cm3) and greater moisture content (88.5% vs. 87.4%) compared with no watering after 8 days prior to harvest. No consistent differences were found in SSC, volume, moisture content or taste of fruits from plots where water was applied 1 or 2 days prior to harvest compared with fruits receiving no water after 8 days. Significantly lower sweetness and overall preference ratings were found for fruits from plots drip-irrigated 4 days prior to harvest compared with those that recei

ved no water after 8 days. In contrast, only sensory ratings of fruits from furrow-irrigated plots might indicate that watering 1 and 2 days prior to harvest may be as detrimental to quality as water applied 4 days prior to harvest.
