INTRODUCTION<\/strong><\/h3>\n

\"\"<\/a>Melon (Cucumis melo<\/em>) is a warm-season crop that is sensitive to temperature\u00a0and thrives well in a hot, dry climate with mean daily temperature of 22-30\u2103. In 2019 we tested 10 different melon cultivars including 5 cantaloupe (Athena, Divergent, Goddess, Sugar Cube, and Sugar Rush), 4 honeydew (HD93, Orange Sugar, Pongo, and Snow Mass), and 1 ananas (San Juan), and we compared yield in a high tunnel and the adjacent open field. Seed was donated by Osborne Seed Company and Harris Seeds. The experimental design was a randomized complete block with 2 replications and 5 plants per plot, planted in a single row. In the high tunnel, rows were flat with no mulch and were spaced 1.8 m (6 feet) apart. In the open field, raised beds were formed and covered with black plastic mulch (1 mil thickness; Filmtech, Allentown, PA), and spacing was 3 m (10 ft.) center-to-center. We recorded number of days from transplanting to first harvest, and measured fruit yield and quality.<\/p>\n

RESULTS<\/strong><\/h3>\n

Days to first harvest were 92\u2013105 in the field and 90\u201398 in the high tunnel, and the average was 98 days in the field and 94 days in the high tunnel. Total fruit weight and number per plant were generally two times greater for all varieties in the high tunnel than in the open field. Pongo had the greatest cumulative fruit weight in both the high tunnel and open field while Sugar Cube, a mini fruit variety, had the lowest cumulative fruit weight in the high tunnel and moderate fruit weight in the open field (Fig. 1). Orange Sugar and HD93 had moderate cumulative fruit weight in the high tunnel but were low in the open field. Weight per fruit ranged from 0.5\u20131.3 kg (1.1\u20132.9 lb) in the high tunnel and 0.2\u20131 kg (0.4\u20132.2 lb) in the open field. Fruit tended to be slightly larger both in weight and size in the high tunnel and overall average was 1 kg (2.1 lb) per fruit compared to 0.7 kg (1.7 lb) per fruit in the open field. The average fruit length was 12.5 cm (range 9.1\u201314.7 cm) in the high tunnel and 11.3 cm (range 9.2\u201313.4 cm) in the open field, while the average fruit width was 11.9 cm (range 9.6\u201313.7 cm) in the high tunnel and 8.1 cm (range 9.9\u201312.7 cm) in the open field. Athena had the largest fruit in the high tunnel. Sugar Cube and Orange Sugar had the smallest fruit in both the high tunnel and the open field. Fruit tended to be sweeter in the high tunnel and overall average was 12.4% soluble sugar compared to 10.6% in the open field. Sugar Rush (14.1% on average) had the highest soluble sugars while Athena (9.1% on average) had the lowest in both the high tunnel and the open field.<\/p>\n
