Growth and Gas Exchanges of Arugula under Phosphate Fertilisation and Irrigation Depths

Abstract

Aims: To study the growth and gas exchanges of arugula plants under water stress and phosphate fertilisation as attenuator. Study Design: The experimental design was randomised blocks, with treatments arranged in a 5 x 2 factorial scheme, corresponding to five doses of P 2 O 5 (0, 50, 100, 150 and 200 mg dm-3) and two irrigation depths, 50% of the real evapotranspiration (ETr) and 100% ETr, with four replicates, totaling 40 experimental units.
