    An experiment was established at the Isabela Experiment Station to determine the effects of sustainable agricultural practices on plant-parasitic nematodes associated to pumpkin (Cucurbita moschata Dutch.). The experimental design was a randomize complete block with six treatments and four replicates. The treatments evaluated were: 1. Rotation of Corn (Zea Mays var. ‘Mayorbela’) + one cycle of pumpkin; 2. Rotation of velvetbean (Mucuna deeringiana) + one cycle of pumpkin; 3. Soil incorporation of poultry litter (7.3 Kg/plant) + two cycles of pumpkin; 4. Soil solarization (period 120 days) + one cycle of pumpkin; 5. Chemical Control (Nemacur 15 G®, 3.0 g a.i / plant) + two cycles of pumpkin; and 6. Absolute Control (two cycles of pumpkin). Significant differences (LSD P<0.05) were observed with phytonematode populations throughout the different treatments. Sustainable agricultural practices showed to be effective reducing populations of plant-parasitic nematodes associated to roots and soil, when compared with the chemical control. The use of poultry litter improved nematode control, plant growth and increased crop yield when compared with the chemical and the absolute treatments. Soil solarization was the most effective treatment reducing phytonematode populations in soil.
