Papaya crop has annual water consumption between 1200 and 2000 mm, well distributed and frequent. The amount of water and the frequency of application differ from one zone to another and depend on soil type, plant age and climatic conditions. However, the average of the irrigation intervals is between 5 and 10 days and the amounts of water to apply between 15 and 40 liters per plant. Periods of active growth and flowering / fruiting require special attention to their water reqirements. Irrigation techniques most employed are: gravity, sprinkler and localized.

The papaya is a plant that has three very special features in relation crop water requirements.

  1. A relatively shallow root system, compared with other species of fruit.
  2. A growing fast and steady development, together with blooms and fruiting.
  3. The plant and its fruits contain about 85 to 90% water.

Throughout the cycle, the crop is attributed annual water consumption between 1200 and 2000 mm, well distributed and frequent. The amount of water and the frequency of application differ from one zone to another and depend on soil type, plant age and climatic conditions. However, the average of the irrigation intervals between 5 and 10 days and the amounts of water to apply between 15 and 40 liters per plant. Periods of active growth and flowering / fruiting require special attention to their water needs. An important aspect in the irrigation, it has water quality. It is recommended not to use those with greater than 200 ppm salinity.with great content of chlorides and in active biological state.

Among the most commonly used irrigation systems can be identified: surface, sprinkler and localized (micro sprinkler and drip).

-Surface irrigation: consists of applying water through furrows constructed on both sides of each row of plants. When these are usually small one is enough and after two furrows are set.

– Sprinkling: It’s an attractive system for its simplicity, but it is highly intensive journey, especially if it is completely portable. It is important that the type of sprinkler is undertree low angle (not more than 7 °) to avoid washing foliage of pesticide products.

– Drip irrigation: It is the most effective and economical way to provide water, nutrients and other substances such as pesticides and growth regulators. Localized irrigation allows constantly improve only a small percentage of soil, root development focus mainly tree within the volume wet by the emisor.

To set and select the type of irrigation system takes into account the following aspects:

  1. The climatic conditions of the region
  2. The source supply (type, characteristic and capacity)
  3. The soil and its properties (type of soil, field capacity, infiltration and saturation, productive limit).
  4. The topography of the site.
  5. The financial resources available       http://www.fruticulturacubana.co.cu/instructivos/IT12_papaya%20instructivo%20tecnico.pdf
