DRIP IRRIGATION FOR PEANUT

Cultural background, origin and dissemination

The peanut (Arachis hypogaea L.) is an annual herbaceous plant belonging to the Fabaceae (or Leguminosae) family and the genus Arachis. The species is native to Central and South America, an area where much of the world’s cultivated area and production is located, along with Asian and African countries (especially Egypt). Its two main uses are the industrial and food sectors due to the seed’s high nutritional value.

Needs and enviromental adaptation

The peanut prefers light, loose, well-drained soil with a sandy tendency. Clay soils, on the other hand, are not recommended, both because they hinder the penetration of the stalks into the soil and because they are more susceptible to water stagnation, which causes the legumes to rot (given their hypogeal growth).

Optimal soil pH is between 5.5 and 7.0, while electrical conductivity must be below 4 dS/m. Ideal temperatures for germination range from 20 to 30°C. It benefits from constant temperatures throughout the vegetative productive cycle, with an optimum of 18-24°C after sprouting.

Irrigation system for peanut cultivation

The best irrigation system for open field peanut cultivation is definitely the drip irrigation system; the Irritec solution consists of the light drip lines with flat dripper (Irritec P0, P1 and P5) which, thanks to the wide range of thicknesses and flow rates available, are suitable for both seasonal and multi-seasonal use.

The possibility of closely placed drip points makes this type of drip line extremely suitable for peanut planting distances (generally 15-20 cm between plants on the row).

In addition, the system with protected outlet (Flap) available for Irritec P1 and P5, avoids problems with the suction of mud and debris following tamping of the soil, an operation which in the peanut is carried out when the gynophores (flower peduncles) are buried: the system acts through a “flap” obtained by means of a special machining of the emission hole.

During the irrigation cycle the flap lifts up and ensures regular water outflow. At the end of the irrigation cycle the flap returns to its rest position, closing the emission hole and consequently blocking any infiltration of mud and debris. This allows the burying and, therefore, also the sub-irrigation use of these hoses as it also minimises the possibility of root intrusion.

Water filtration

Water filtration is essential. Irritec has a wide range of filters to cover all the needs of modern irrigation systems: from classic hydrocyclone sand separators, suitable for primary filtration of well water, to screen filters (mesh or disc) in plastic or metal versions, useful for secondary or sector filtration, to quartzite filters, indispensable in the case of difficult to filter water (high turbidity, presence of algae and other organic residues).

In addition to the manual versions, Irritec offers automatic backwashing systems (filter batteries consisting of 2 or more modules): by means of electrically or battery-operated control units, it is possible to set the duration and frequency of the washings, thus ensuring optimal washing of the filtering mass. Filter cleaning can be managed either by time or by sensor (pressure differential).

Fertigation

Despite its rapid biological cycle, the peanut benefits from precise and fractioned fertilisation throughout the cycle, with ad-hoc interventions at flowering and seed maturity.

For peanut fertigation, Irritec offers simple and efficient systems that allow fertilisers to be distributed directly into the irrigation water, limiting potential damage from nutritional deficiencies.

Ferticlick bypass, for example, is a well-suited instrument for open field fertigation of vegetable crops such as peanuts: consisting of an easy-to-program electronic board, a Venturi bypass, a volumetric counter (10 pulses/litre) and a common solenoid valve, it is an accurate system for the simple proportional or volumetric fertigation of a fertiliser.

Here are the Irritec products you need to drip irrigate peanut

1

P1®

With its wide range of thicknesses and availability of flow rates, the light drip line with P1 flat dripper allows both seasonal and multi-seasonal use. The flat dripper guarantees extremely low, localised head losses, with the possibility of realising a drip line of significantly greater lengths for each of the many diameters available.

LOW DENSITY POLYETHYLENE PIPES

The low density irrigation pipe is produced with state-of-theart equipment, using selected special resins that are highly resistant to chemicals and weathering. Due to its high resistance to mechanical stress, it is particularly suitable for side branches and withstands deformations caused by the assembly of hose couplings very well.

FILTERS

Irritec’s line of metal filters offers complete and extremely robust solutions. The product range is divided into sand filters, screen filters and hydrocyclone sand separators. The special care taken in the construction and the use of high gauge metal make this filter line the right solution for the toughest applications and the most difficult waters. Irritec metal filters are also protected by a thick epoxy paint that protects the metal from corrosive events over a long period of time. Manual or automatic models are available for canal and well water applications.
