The advantages they bring include pest and disease control, as well as an increase in plant yield. Intersemillas is committed to organic farming and works tirelessly to provide tools and materials that help farmers achieve the best results in organic watermelon cultivation. As is customary with this fruit, grafting is part of the watermelon cultivation process to help increase plant yield with strong roots, control pests and diseases, and enhance resistance to environmental stress. Thanks to their intensive work and strong commitment to R&D, Intersemillas guarantees 100% organic cultivation with its two most effective rootstock varieties: Robusta Eco and Shintoza Eco.

Robusta Watermelon rootstock. In the nursery, this rootstock performs well with less vigorous plants, without hollow stems, allowing for successful variations in the grafting method. Robusta is resistant to nematodes in highly contaminated soils and helps increase the sugar content of the watermelon while reducing skin thickness.

Shintoza It is a C. maxima by C. moschata rootstock resistant to Fusarium oxysporum, with a powerful root system that minimally interferes with the characteristics of the grafted variety. This allows for good results in the field, both in fruit quality and productivity. Shintoza achieves high, uniform germination in the nursery, increasing the yield of the grafted plant. For grafting, Intersemillas relies on two watermelon varieties, Menina and S-10979. The former is a productive variety with very few microseeds, weighing 2-2.5 kilograms, finely and darkly striped with a white background. On the other hand, S-10979 is a crimson watermelon with microseeds and very few seeds, recommended for monoculture, providing fruits weighing 2-3 kilograms with good internal color, high brix degrees, and high production.
