An experiment was carried out to evaluate the effects of irrigation levels, based on fractions of the class A pan evaporation, on yield and the chemical and physical characteristics of muskmelon cultivar Bonus nº 2 grown under plastic house conditions and drip irrigation in Roraima State, Brazil. The experimental design was randomized blocks with six treatments (0.20; 0.40; 0.60; 0.80; 1.00 and 1.20% of ECA) and four replications. The results of yield showed a linear response of the applied irrigation levels, with values of 4 kg m-2. All others physical characteristics, except for pulp firmness, showed a linear response to irrigation treatments. Total soluble solids showed a linear decreasing response with respect to the irrigation levels with values between 10.4 and 11.7º Brix, while fruit pH was not affected by treatments, averaging 6.74.
