“…DRIS standards have been successfully used to interpret leaf analysis results in different annual and perennial crops, such as pine (Sanchéz-Parada, López-López, Gómez-Guerrero, & Pérez-Suàrez, 2018); rubber (Chacón-Pardo, Camacho-Tamayo, & Bernal, 2018); sugarcane (Mccray, Ji, Powell, Montes, & Perdomo, 2010;Santos, Donha, Araújo, Lavres Júnior, & Camacho, 2013); common bean (Partelli et al, 2014), potato (Queiroz, Luz, Oliveira, & Figueiredo, 2014), rice (Wadt et al, 2013), cotton (Serra et al, 2013;Kurihara, Venegas, Neves, Novais, & Staut, 2013), guava (Souza, Rozane, Amorim, & Natale, 2013), mango (Politi et al, 2013), orange (Dias et al, 2013), apple (Xu, Zhang, Wu, & Wang, 2015), and grape (Teixeira, Tecchio, Moura, Terra, & Pires, 2015). However, no studies on U. brizantha pastures and their nutritional diagnoses based on DRIS norms are available.…”
