Melon (Cucumis melo L.) Fruit Yield under Irrigation and Mycorrhiza Conditions

The size and quality of the melon fruit yield depend on cultivar, climatic agronomic factors. A three-year field experiment investigated effect arbuscular mycorrhizal fungi (AMF) application irrigation (IR) (Cucumis melo L. var. saccharinus Naud.) cultivars. study was conducted a certified organic farm located in south-eastern Poland (51.36° N, 22.83° E). factors were as follows: cultivar (Melba, Emir F1, Seledyn Oliwin) cultivation method (AMF IR; AMF non-IR; non-AMF non-IR control). dry matter (%), soluble solid total sugar reducing (% fresh weight, FM), L-ascorbic acid (mg · 100 g−1 carotenoid FM) contents determined. highest marketable yields obtained using IR. Fruit from series (IR non-IR) had most carotenoids (respectively: 801.5 788.8 µg FM). fruits IR plants contained sugars (5.98%) (2.91%) compared to others. control lowest number fruit, yield, accumulated least acid, sugars. We suggest that can be recommended practical solutions for under temperate climate conditions.
