- Abstract
The pumpkin crop is becoming outstanding in the world scenario due to growing concern with the issue of food challenge and its production characteristic associated with small properties. There is little information in the literature about pumpkin responses to irrigation management associated with nitrogen fertilization. The objective of this work was to evaluate productive performance (number, fresh weight, dry weight and productivity) and quality parameters (diameter, length, pulp thickness and ° Brix of the fruits) of pumpkin culture under irrigation levels associated with doses of nitrogen fertilizer. A randomized complete block design was used in subdivided plots, where the nitrogen dose factor (50; 70; 100; 125% kg of N ha-1) was inserted in the plots and in the subplots, irrigation depths (50; 75; 100; 125% of evaporation measured in tank class A - 'ECA') with four replicates. The research was conducted in the experimental area of the Meteorological Station belonging to the Federal University of Ceará. The maximum productivity reached was 4269.6 kg ha-1 obtained with the combination of water blade of 444.10 mm (122.5% of ECA) and nitrogen level of 33.65 kg ha-1 of N (112.16% of the recommended N).
