Séminaires Méditerranéens SP - 147-150 A2 - Cantero-Martínez C. A2 - Gabiña D. AB - At some specific stages of wheat (Triticum aestivum L.) growth, commercially available organic growth stimulants (biostimulants) were tested from 1999 to 2003 in Saudi Arabia. Small amounts (up to a few l per ha) of biostimulants (Vigro, Biomin, Humiplus and Humacare) were used and evaluated on wheat crops. These products consisted of micronutrients, humic acid, extracts of seaweeds, plants and amino acids. Field tests of these substances at various nutrient levels, locations, forms and timings resulted in enhanced crop yields and produce quality. Improvement of plant growth and increases in yield were observed for all biostimulants, but Vigro showed significant yield increases. The plants treated with Vigro exhibited an increase in the total tiller number of 21 percent, a greater number of fertile florets per spike. Nevertheless the economic yield (grain yield) had improved by 8.2 percent.
