Pumpkin Cobalt

Cobalt pumpkin is a hybrid rootstock developed by Rijk Zwaan, designed for cultivation in open ground. This hybrid is characterized by its early maturity and green-colored fruit, making it versatile and suitable for various climatic conditions and regions. The product meets high quality standards and ensures a stable yield.

The main advantage of the Cobalt pumpkin is its resistance to diseases such as fusarium, verticillium, and phytophthora, significantly reducing the risk of crop losses. Additionally, using this rootstock promotes stronger plant growth and increases the yield potential of grafted plants, positively affecting both the quantity and quality of the harvested fruits.

The Cobalt hybrid is widely used for grafting cucumber, melon, and watermelon plants, especially in challenging climatic and soil conditions such as heavy soils, salinity, and disease presence. Grafting onto this rootstock allows plants to develop a robust root system and extend the vegetative period, which contributes to improved overall plant health and increased productivity.
