The green bean is a legume with ample potential for human consumption due to its dual use, both the grain and the pod, and its high protein content. Additionally, part of its production is marketed in frozen and canned forms. However, progress is needed through genetic improvements and cultivation techniques to enhance its development.
The countries that import Spanish green bean harvests include France, Germany, Switzerland, and the United Kingdom.
In the Iberian Peninsula, the cultivated bean varieties are generally sensitive to photoperiod, classified as short-day plants. However, some genotypes modify their sensitivity to day length depending on the temperature (Ehlers & Hall, 1996). The combination of high temperatures and long days can reduce or inhibit the formation of flower buds, while nighttime temperatures above 20°C during the flowering period can lead to a decrease in pod formation and yield loss (Nielsen & Hall, 1985).
Therefore, in bean cultivation in the Iberian Peninsula, it is essential to pay special attention to the flower drop disorder, as it is the most vulnerable organ to deficiencies. Additionally, this drop can be exacerbated by abrupt changes in humidity and temperature or by management geared towards vegetative development due to excessive nitrogen.
Furthermore, it is important to consider the rapid senescence of the crop to achieve adequate profitability in relation to investments made, avoiding the occurrence of physiological aging known as “rusting,” which can also be caused by excessive moisture.
In response to these issues, Cultifort recommends solutions with multi-active compounds to mitigate these crop disorders, such as the product Cultimar plus. Cultimar plus is a stimulant that contains easily assimilable active principles from seaweed, such as cytokinins, essential oils, sugars, proteins, mineral salts, vitamins, amino acids, and carbohydrates. These components contribute to improving the balance between plant development and production by delaying the senescence of active plant parts and overcoming abiotic stress conditions related to temperature, humidity, and osmoregulation.
Cultimar plus is characterized by being formulated as an emulsion, ensuring effective application of phytoregulators. This allows for the promotion of high cell division in non-meristematic tissues and organ formation, thus delaying senescence and providing significant inputs of carbohydrates, amino acids, and osmoregulatory mannitol, which supply energy rapidly to plant cells and participate in respiratory processes, reducing water stress.
In summary, Cultimar plus presents itself as a natural solution with significant benefits for managing the primary crop disorders.
