Production and Quality of Melons Under Different Arrangements of the Irrigation System and Ground Cover

Authorship SCIMAGO INSTITUTIONS RANKINGS

Abstract

The aim of this work was to evaluate productive and quality aspects of melons (Cucumis Melo L.) under different forms of cultivation in Petrolina/PE during two cycles of production. A randomized block design was adopted with sub-divided plots in a 2 x 2 x 3 factorial scheme, with two yellow melon hybrids (Gladial and SF 10/00 F1) in the plots, two irrigation system arrangements (one and two rows drippers per row of plants) in the subplots, and three types of soil cover (black and gray mulching and without cover) in the subplots, with six replications. Were evaluated length, width, total and commercial number of fruits, productivity, efficient use of water, total soluble solids, firmness and acidity of the pulp were evaluated. The highest rates of productivity, efficient use of water and number of commercial fruits were obtained with the use of mulching (regardless of color) with a row of drippers per row of plants. For post-harvest rates, the treatments did not differ.
