Cultivation classification and dissemination

Melon (Cucumis Melo L.) is a vegetable species belonging to the family cucurbitaceae and the genus cucumis. The three main varieties cultivated include the cantaloupe melon, the honeydew melon and the winter melon, which differ in the shape and size of the fruit, the colour and roughness of the rind, and the colour and aroma of the flesh. The melon is now widely cultivated worldwide, especially in China, Turkey and Iran.

Water requirements

The seasonal water needs of melon are very high: the total water intake, in fact, varies from 4000 to 6000 m3/ha (source FAO-56). These water intake figures must be interpreted according to seasonal climate trends (based on rain estimates and data received from weather stations) and in accordance with the company’s production goals.

Irrigation system for melon

The irrigation system that is most suitable for melon cultivation is undoubtedly the drop-by-drop system, which makes it possible to pursue the goal of delivering the strictly necessary volume of water to the plant while limiting waste both in terms of water (through low flow rates and extreme localisation of the drop) and energy (through low operating pressures).

In addition, short and frequent irrigation shifts improve the efficiency of irrigation, ensuring that the plant remains in an optimal water status.

Driplines and tubing

With reference to the more classic melon cultivation systems (in the open field or in forced cultivation under greenhouse tunnels), the irrigation system provides for the installation of a single light dripline (6-8-10-12 mm thick) along the row of seedlings, under the mulching cloth; typically, drop point spacing of 20-40 cm is used, with flow rates ranging from 2 to 4 l/h.

With this in mind, Irritec recommends the use of Irritec Tape or Irritec P1, Irritec’s historic lightweight dripline with a flat drip head which, thanks to its wide range of flow rates, spacings, thicknesses and diameters, is synonymous with reliability, excellent performance, durability and versatility.

For the main and header tubing and the classic polyethylene tubes, Irritec recommends the LayFlat tube, which, being light, flexible and easily rewindable at the end of the season, is well suited to cultivating melons, which are usually rotated in different plots.

Filtration system

The filtration system is the main element of a drip system. It safeguards the irrigation system from occlusion and ensures that each drip head delivers the design rated amount, ensuring uniformity to each sector.

Irritec offers a wide range of filters, suitable for different sources of water supply. Generally, after primary filtration by de-sander (hydrocyclone), with quartzite filters or, again, with disc filter coils (in manual or automatic versions), Irritec recommends the use of mesh or disc sector filters, which provide additional security for the driplines.

Fertigation for melon

In order to achieve a good level of production, it is important to equip the irrigation system with a fertigation system capable of injecting fertilisers into the pipeline as precisely as possible. In fact, despite the short duration of the cultivation cycle, the melon, due to its morphological and physiological characteristics (creeping bearing, covering leaves, intense growth rate), benefits greatly from fertilisers suitably integrated with the irrigation practice; insufficient availability of nutrients can lead, for example, to a reduction in vegetative growth and the production of small fruits.

For fertigation of melons, Irritec recommends simple and extremely versatile systems for both open field and greenhouse-tunnel applications: one can opt for classic Venturi systems or for the Ferticlick bypass, a device that allows a single nutrient solution to be injected into the pipeline in a volumetric (50 to 500 l/h) or proportional manner (a meter with a pulse emitter – 100 or 1000 l/impulse, is required to be installed on the main line).

The proportional administration of fertiliser diluted in water clearly increases the efficiency of fertigation practice because, unlike the volumetric method, it improves the absorption processes by the plant.
