Irrigation of artichokes is an important method of increasing yield and bringing crop production forward. However, although early production is advantageous for the best market prices, it can also be detrimental as high summer temperatures can result in withering of the flower heads. For this reason irrigation should not begin before late JULY, and continue into the autumn.
For optimal yield using sprinkler irrigation, the following is recommended:
- irrigation cycle between 7 and 10 days;
- the first watering, to stimulate artichoke production, can take place in JULY, using approximately 800 cubic metres per hectare (in sufficiently deep soils);
- for subsequent watering, volume used should be around 500 cubic metres per hectare;
- the maximum number of irrigation cycles should be no more than 7 or 8.
With drip irrigation, the following is recommended:
- shorter irrigation cycles, increasing the number to 11-12;
- The volume of water used for each intervention should be no greater than 300 cubic metres / hectare.
