Agricultural crop performance can be improved with use of seaweed extracts. The aim of this study was to evaluate the effects of Ascophyllum nodosum extract on biometric, biochemical and yield parameters of the wheat. The experimental design was completely randomized with 3 treatments [control (water), seed treatment (0.1 mL of the A. nodosum extract on the 100 g of seeds) and soil irrigation (5 mL L-1 of seaweed extract, which was applied at 14th, 28th and 42nd days after sowing)] and 10 replications. Plants irrigated with A. nodosum extract showed increments in the height, dry mass of shoots and number of spikes (10.72%, 22.22% and 13.19%, respectively), however these plants had the lowest harvest index (reduction of 17.12%), when compared to the control. Seed treatment also increased plant height, but it did not change biochemical and productivity parameters. It is concluded that soil irrigation with 5 mL L-1 of A. nodosum extract provides development and positively affects production of ‘IAC 364’ wheat.
