Características morfológicas de Urochloa brizantha cv. Marandu adubadas com silício na aplicação do calcário

Abstract: O experimento foi implantado no viveiro de mudas da Prefeitura de Descalvado (SP). Teve por objetivo avaliar características morfológicas de Urochloa brizantha cv. Marandu adubadas com fontes de silício (silicato de cálcio e silício orgânico) e doses representativas a 0, 100, 200, 300 e 400 kg/ha e uma testemunha. O delineamento de parcelas sub-divididas deu-se em fatorial de 2 x 5 x 4 (fontes de silício x doses de silício com 4 repetições). Foram avaliadas as seguintes características morfológicas da planta: … Show more
