Comparative Study of an Artichoke Crop Under Drip Irrigation
Researchers at the Miguel Hernández University studied an artichoke crop under drip irrigation, using as treatments, on the one hand, emitters of high and low discharge, and on the other, high and low frequency of irrigation.
Artichoke (Cynara scolymus L.) is a widespread crop in Mediterranean regions, where irrigation depths of 5 000 to 6 000 m3•ha-1•year-1 are usual for this winter crop. In this regions, drip irrigation is the most common irrigation system but there is not a clear recommendation of the better combination of emitter discharge and irrigation frequency for Artichoke under those environmental conditions.
In this work we conducted a comparative study of an artichoke crop under drip irrigation using
– high discharge emitters (4 L•h-1) and low irrigation frequency (T1), and
– low discharge emitters (1.6 L•h-1) and high irrigation frequency (T2).
A Blanca de Tudela crop was planted in August 2017 and finished in May 2018 following common agricultural practice. A randomized blocking design was used, with three blocks for each treatment, 20 plants per block and one guard row between blocks. Irrigation interval changed according to plant water requirements along the cropping cycle. The total irrigation depths applied were 5842 m³•ha-1 and 5740 m³•ha-1, with average irrigation frequencies of 6.4 and 2.7 days, in T1 and T2 respectively. The first Artichoke cut was made on November 29 and the last one on May 15, with 16 cuts and an average harvest interval of 11 days.
The results show a greater number of flower-heads and total production for T2, a larger size per flower-head for T1.
