dc.descriptionSilicon (Si) accumulation in plants may reduce yield losses by inducing resistance to both abiotic and biotic stresses. This study aimed to evaluate the Si accumulation by lignocellulosic sorghum (Sorghum bicolor) in a greenhouse experiment, as well as the effect of its application on agricultural traits and on the induction of resistance against anthracnose (Colletotrichum sublineolum) in a field experiment. Sixteen sorghum genotypes were evaluated in a greenhouse for their response to silicate fertilization, receiving either 0 kg ha-1 or 261 kg ha-1 of Si, measuring the Si concentration in the sorghum shoots. Four genotypes that were responsive to Si fertilization were tested in the field, receiving either 0 kg ha-1 or 400 kg ha-1 of Si, being evaluated the Si concentration on the leaves, plant height, lodging percentage, anthracnose disease severity, grain yield and plant fresh and dry matter. The response of sorghum to Si fertilization in the greenhouse varied with the genotype and, of the 16 genotypes evaluated, 12 were responsive, accumulating more Si after the fertilization with this element. All four genotypes tested in the field were responsive, but no effect of Si was observed on grain yield or on sorghum fresh and dry matter production. However, the soil Si application reduced the plant lodging and anthracnose severity ratings in sorghum.
