Exploring Innovative Carob Orchards with Rosa Hernandorena

In Valencia, together with Rosa Hernandorena of Viveros Hernandorena, Agronomist Dr. Vito Vitelli visited several modern carob orchards that demonstrate how the carob tree can now be transformed into a highly modern, efficient and profitable crop.

For many years, the carob tree was considered a slow-growing and marginal species, confined to the driest areas of the Mediterranean region. Today however, thanks to innovations in nursery production and modern agronomic management, It is possible to achieve attractive economic returns just a few years after planting.

In the orchards visited in Valencia, three-year-old trees already display excellent structure, strong branching and significant early production levels. These results are the outcome of a combination of proper cultivar selection, rational irrigation, balanced nutrition and modern canopy management.

Many of the elements observed closely reflect the principles of the Zaragoza System, which Dr. Vito Vitelli has already successfully applied to almond, pistachio and hazelnut cultivation. The objective is not to develop excessively large and difficult-to-manage trees, but rather more compact, well-illuminated and balanced structures capable of entering production rapidly while reducing management costs.

Particularly noteworthy is the widespread adoption of new hermaphrodite varieties, which are capable of self-pollination without the need for separate male trees. This represents a major advantage compared to traditional carob orchards, improving both production consistency and overall orchard efficiency.

From an agronomic perspective, the carob tree continues to demonstrate its remarkable adaptability to Mediterranean environments. It performs well in calcareous, poor and stony soils but is sensitive to waterlogging. For this reason, slight raised beds and careful water management are essential. In the orchards visited, two irrigation lines are used with moderate water applications.

Planting layouts have also been completely modernized compared to the past. With spacing of approximately 6 × 5 meters, planting densities can reach nearly 330 trees per hectare, accelerating productive space occupation and improving overall photosynthetic efficiency.

In recent years, the carob tree has also regained significant commercial interest due to growing demand from the food and cosmetics industries. The pulp is used for flour production and alternative food products, while the seeds are processed into natural thickening gums that are highly sought after by the international confectionery industry. Increasing attention to plant-based nutrition, sustainability, and natural ingredients is bringing this ancient Mediterranean species back to the forefront of new production opportunities.

The technical visit to Valencia therefore confirms an increasingly evident reality: the carob tree can represent a concrete opportunity for many Mediterranean areas of Italy, particularly in the driest and most challenging territories, where climate change and water scarcity require more resilient and efficient production models.
