Different tomato cultivars may present differentiated water needs, making it
indispensable to study water demand. Thus, the objective of this work was to evaluate the
influence of six water stresses in the soil on the extraction potential of macro and micronutrients
in the aerial part of tomato in vegetative stage, cultivar ‘Dominador’ F1, under protected
cultivation and drip. The experiment was installed in a greenhouse with a randomized block
design with four replications. The treatments consisted of six soil water stresses as indicative of
the time of irrigation. The preset stresses were 20, 45, 70, 95, 120 and 145 kPa at 20 cm depth.
At 140 days after transplanting, the variables evaluated were: the macro and micronutrient content
of shoots. The results showed that to obtain higher levels of macro (P and S) and micronutrients
(B and Cu) of the total aerial part of the ‘Dominador’ tomato plant F1, it was obtained at a voltage
of 20 kPa, and its value was reduced linearly with the increase of the water tension in the soil.
