Zucchini cultivation in Spain: agronomic management and preventive nutrition
Zucchini (Cucurbita pepo) is one of the most cultivated vegetables in SpainIt thrives both outdoors and in greenhouses. Its rapid growth cycle, high productivity, and strong demand in national and European markets make it a strategic crop within Spanish horticulture.
To get continuous production, homogeneous fruit and high commercial qualityIt is therefore essential to apply appropriate agronomic management and a balanced and preventative nutritional strategy.

History and origin of zucchini cultivation
Zucchini belongs to the Cucurbitaceae family and originated in America, where the species of the genus Cucurbita They had been cultivated for over 7.000 years. After the discovery of the New World, these plants were introduced to Europe, quickly adapting to the Mediterranean climate.
Although the consumption of the immature fruit —as zucchini is known today— became popular later, especially in Italy, Spain quickly adopted its cultivation due to its ease of handling, speed of production and culinary versatility.
Currently, zucchini is a key crop in Spanish horticultural calendars, especially in early and export productions.

Importance of zucchini cultivation in Spanish horticulture
According to the latest official data from Ministry of Agriculture, Fisheries and Food (MAPA)The area dedicated to zucchini cultivation in Spain is around 9.000–10.000 hectaresconsidering both open air and greenhouse.
Approximate distribution by Autonomous Communities
| Autonomous community | Estimated area (ha) | predominant system |
| Andalucía | ~4.500 hectares | Greenhouse / Outdoors |
| Murcia | ~2.000 hectares | Outdoors / Greenhouse |
| Valencian Community | ~1.200 hectares | Fresh air |
| Castilla la Mancha | ~600 hectares | Fresh air |
| Catalonia | ~500 hectares | Fresh air |
| Canary Islands | ~200 hectares | Greenhouse |
| Total Spain | ~9.000–10.000 ha |
Andalusia and Murcia account for most of the production, with early crops grown under cover and geared towards export being particularly noteworthy.
Climatic requirements for zucchini cultivation
Zucchini is a fast-growing crop, but very sensitive to environmental and nutritional stress.
Temperature, light and sensitivity to thermal stress
- Optimum temperature: 20–28 ºC
- Very sensitive to low temperatures (<10 ºC)
- High demand for light
- Sensitive to sudden temperature changes
Texture, drainage, pH and organic matter
- Loamy or sandy loam texture
- Good drainage
- optimal pH between 6 and 7,5
- Good organic matter content
A well-structured and microbiologically active soil promotes rapid and uniform crop development.
Stages of zucchini cultivation and agronomic management
Transplanting and rooting
Key phase due to the speed of the cycle.
- Rapid root development
- Reduction of initial stress
- Uniform crop start-up
Vegetative development
Zucchini develops a large mass of leaves in a short time.
- Balance between growth and production
- Avoid excess nitrogen
- Maintain good aeration of the plant
Flowering and fruit set
Very sensitive to adverse conditions.
- Flower drop due to heat stress
- Importance of boron and calcium
- Need for biostimulation to ensure continuous fruit set
Fruit development and harvesting
The fruit grows rapidly and is harvested immature.
- Potassium for size and quality
- Calcium for firmness
- Micronutrients to prevent deformities
Preventive management of zucchini cultivation
Because of his short cycle and high production intensityZucchini requires constant preventative management:
- Avoid production stoppages
- Reduce physiological stress
- Maintaining continuity in flowering
- Improve fruit uniformity
Proper preventative nutrition is key to maximizing crop profitability.
