Pumpkin (Cucurbita moschata) is a plant commodity that has the opportunity as an alternative food crop. Various efforts have been made to increase pumpkin production, such as by developing plant cultivation techniques. The use of mulch and organic fertilizers can be a solution to increase production while implementing sustainable agriculture. This study aimed to determine the response to the use of various types of mulch and the application of various types of organic fertilizers on the growth and yield of pumpkin plants. This study used a Factorial Completely Randomized Design (CRD), with the first factor being the type of mulch (plastic mulch, organic mulch, and without mulch) and the second factor being the type of organic fertilizer (compost, cow manure, and no organic fertilizer). The results showed that the interaction of treatment using mulch and applying organic fertilizer was significantly different on vegetative growth, especially at the age of 6 and 8 Weeks after Planting (WAP), but not significant for pumpkin fruit yields. Separately, organic fertilizers have more effect on the growth and yield of pumpkin plants than the use of various types of mulch. In addition, plastic mulch treatment with compost had the highest stem diameter growth, number of leaves, and number of branches. Then the treatment of organic mulch with compost has the highest productivity estimation results. Separately, compost was also able to produce the highest number of fruits (113 pieces/plot) and the highest estimated productivity (13.19 tons/ha).
