“…Conspecifi c interactions were more negative than heterospecifi c interactions for four of the fi ve interspecifi c pairings in which H. annuus with L. perenne and P. smithii with A. millefolium had the greatest aboveground biomass response with heterospecifi cs in this study and corroborates the generality that intraspecifi c neighbors compete more intensely than interspecifi c neighbors (ADLER et al, 2018). These outcomes also add to evidence that species vary in whether they compete more intensely with intraspecifi c relative to interspecifi c neighbors (CRUZ et al, 2020;LI et al, 2020), and the magnitude of benefi t towards aboveground productivity varied between 26.02% and 65.39% greater growth with a heterospecifi c plant. Whether and how much a population of a species has improved growth with a heterospecifi c plants represents an important avenue for evaluating plants used for mixtures in both agricultural and restoration contexts.…”

“…sis of phenomenological interaction experiments in which intraspecifi c competition largely was more intense than interspecifi c competition. However, other studies have shown variability in whether plants compete more intensely with interspecifi c neighbors (CRUZ et al, 2020;LI et al, 2020). Furthermore, the difference in plant size is important to determining interaction outcomes and can produce a hierarchy of inferior and superior competitors (KEDDY et al, 2002); this may infl uence the relative strength of interspecifi c and intraspecifi c interactions.…”

“…Dentre os seus atributos, o sorgo apresenta baixa exigência hídrica, com alta tolerância a ambientes secos, elevado rendimento forrageiro e baixa necessidade quanto a fertilidade do solo, além de apresentar capacidade de rebrota, permitindo outras colheitas em uma mesma estação de crescimento (Pino e Heinrichs, 2017;Cruz et al, 2020), além disso apresenta crescimento rápido e tolerância a eventos climáticos severos (Xiao et al, 2021).…”

“…A eficiência de utilização de nutrientes por uma cultura está baseada na conversão da quantidade absorvida de nutrientes em kg de matéria seca produzida (Silva et al, 2014). Assim, a cultura do sorgo dispõe de inúmeros trabalhos na literatura onde se indica a quantidade de nutrientes que foi aplicado aos sistemas e a produtividade final da cultura (Cavalcante et al, 2018;Cruz et al, 2020;Frias et al, 2018;Jardim et al, 2021b;Kirchner et al, 2019). Com isso é possível determinar a quantidade produzida em função da quantidade de nutriente aplicado.…”
