DRIP IRRIGATION FOR MANGO TREES

Classification and dissemination

Mango (Mangifera indica L.) is an arboreal species belonging to the family Anacardiaceae. Originating in India, it has gradually spread to several tropical and subtropical areas of the globe. The main Mediterranean countries where mango is grown are Spain and Israel, with niche production in Sicily as well.

Water requirements of mango tree

Its tropical origins imply complex and intricate water requirements, strongly correlated to the cultivation area, the nature of the soil, the annual rainfall trend, the planting quarters, the cultivated varieties and the rootstocks used.

The mango plant is definitely well suited to localised irrigation (drop by drop), which, in addition to making light use of the water supply, also allows fertilisers dissolved directly in the irrigation water to be delivered in a precise and fractional way.

The flexibility offered by drip systems means that irrigation volumes and irrigation recipes can best be modified according to the age of the plant and, in particular, its current phenological stage.

Filtration system

A good irrigation system must be equipped with a properly sized filtration system: Irritec offers a wide range of filters, suitable for different sources of water supply. Generally, after primary filtration by de-sander (hydrocyclone), quartzite filters or even 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.

Irrigation system for mango tree

The ideal irrigation system for a mango plantation consists of a system of drip lines, 1 or 2 per row, laid on the ground (in some cases even under the mulching cloth), a very accurate filtration system that protects the dispensers from possible occlusion problems, from a professional fertigation system suitable for the open field to a programmer that allows simple and professional management of shifts and irrigation volumes.

For companies made up of plots of land with regular topography and short rows, Irritec recommends the normal Tandem or Junior type driplines, while for plots with large differences in height and/or with rather long rows, the self-compensating Multibar F (flat drip head) or Multibar C (cylindrical drip head) version should be chosen; the spacing between the drop points and the hourly rate depend on plant spacing and the textural characteristics of the soil.

A rainfall rate per hectare of 1.0 mm per hour is planned for, making it easier to set up the volumes and shifts dictated by the evapo-transpirative demands of the environment throughout the cultivation cycle.

Fertigation and automation

Depending on the physical and chemical analysis of the soil and the water for irrigation, carried out in the preliminary phase of planting, it is necessary to provide the correct amount of nutrients as soon as the plants are planted in order to promote the best vegetative-productive development.

For field crops such as mango Irritec recommends fertigation benches that are easy to use but capable of accurately injecting fertilisers into the pipeline, taking into account fundamental parameters such as pH and electroconductivity.

Dosabox Junior Automatic, for example, is a device that can handle 3 fertilisers in proportion to the pipeline flow rate, continuously monitoring the above parameters. The advanced version of the Dosabox, thanks to the integrated Commander NPK, allows 3 fertilisers + acid to be managed in a proportional, volumetric way or targeted to EC and pH; the unit also manages the fertiliser
stirring system and up to 4 digital meters (1 for water and 3 for fertilisers).

Finally, the programmers in the Commander EVO line guarantee reliability in setting irrigation shifts and watering volumes, also allowing you to minimise management costs mainly related to opening and closing the solenoid valves, cleaning the filters and the fertigation settings.

The option of installing volumetric meters, weather stations and agri-environmental monitoring sensors makes it possible to assess the real water stress of the crop and deliver what the plant actually needs.

Here are the Irritec products you need to drip irrigate mango trees

1

TANDEM® AND MULTIBAR™ C

Tandem is Irritec’s classic dripline with a cylindrical drip head. The drip head with double perforation makes it possible to increase the surface area to be irrigated. Its four emission holes, positioned opposite to one another prevent the aspiration of impurities. The classic dripline with cylindrical (Multibar C) or flat (Multibar F) pressure compensating drip head is ideal for irrigating multiseasonal crops and is suitable for sloping terrain and uneven topography. The special design of the drip head allows efficient pressure compensation within a very wide range.

TUBING IN PE AND CONNECTO™

Single-ply PVC flexible pipeline reinforced with a high-strength fabric that is easy to handle and store. Facilitates end-of-season operations for irrigation systems that need to be moved quickly and safely. Lightweight and flexible yet durable, it reduces installation costs and recovery time. Easy to cut and equipped with a wide range of connections, the layflat pipe system is an indispensable accessory for drip irrigation of tomatoes. Available from 2.4 to 6 bar, in all commercial diameters from 1 1/2″ to 8″.
