Knowledge of the decomposition dynamics of aboveground phytomass and its release of nutrients in mixtures of cover crops as well as the impact on the soil tillage system is fundamental for the sustainable management of agroecosystems. This work aimed to evaluate whether soil tillage and the choice of cover crops cultivated in the interrows can be technological strategies to increase dry biomass production, increase the capacity to add carbon, and improve macronutrient cycling in a mango (Mangifera indica L.) orchard in a semi-arid environment. The field experiment (sixth year) consisted of two soil tillage systems (NT-no tillage and CT-conventional tillage) combined with three plant mixtures (PM1-75 % leguminous + 25 % grasses and oilseed species, PM2-25 % leguminous + 75 % grasses and oilseed species, and SV - spontaneous vegetation). Phytomass production and nutrient accumulation were not affected by the soil tillage system, but PM1 had the highest phytomass production and accumulations of C, N, and K, and it was significantly superior to SV. Regardless of the type of plant mixture, cultivated or spontaneous, soil tillage increased the rates of phytomass decomposition and nutrient release evaluated for 315 days after the cover plant management. The PM1 had the highest rates of decomposition and release of P and K, followed by PM2 and SV. There was no difference between the mixtures for the release of N, Ca, and Mg. The use of a mixture of cover crops, regardless of the predominance of leguminous or non-leguminous species, and a no-tillage system were technological strategies that could be adopted to favor the addition of soil carbon and nutrient cycling in fruit agroecosystems in the Brazilian semi-arid region. Spontaneous vegetation, due to its capacity to accumulate nutrients and the recalcitrant characteristics of its phytomass, has the potential to cycle nutrients and keep the soil covered. In addition, spontaneous vegetation should be better investigated because it is a low-cost MenosKnowledge of the decomposition dynamics of aboveground phytomass and its release of nutrients in mixtures of cover crops as well as the impact on the soil tillage system is fundamental for the sustainable management of agroecosystems.

Resumo: Objetivou-se avaliar a influência de dietas formuladas com diferentes proporções de volumoso:concentrado (V:C) sobre o consumo de matéria seca, consumo alimentar residual, volume globular no sangue, ovos por grama de fezes (OPG), e dados de emissão de metano em cordeiros infectados artificialmente com Haemonchus contortus. O delineamento utilizado foi inteiramente casualizado, em esquema fatorial 4 x 2 (quatro dietas 70:30, 66:34, 43:57, 36:54 de proporção V:C), infectados ou não com Haemonchus contortus. Foram utilizados 32 cordeiros machos, com peso inicial médio de 26,6 kg e cinco meses de idade. Os dados foram submetidos à análise estatística e as médias dos dados comparadas pelo teste Tukey, em nível de 5% de significância. O incremento nas proporções de PB e NDT dietéticos resultou na melhoria da eficiência alimentar, desempenho, incremento da resiliência de ovinos ao Haemonchus contortus e mitigação das emissões de metano entérico. Nesse sentido, recomenda-se dietas com 66 e 43% de volumoso com valores de PB e NDT de 11 e 63% e 13,94 e 70%, respectivamente. Dietas com maior aporte de proteína e energia associados, com pelo menos 66% de volumoso, podem garantir melhores resultados considerando os parâmetros avaliados. Abstract: The aim of this study was to evaluate the influence of diets formulated with different roughage:concentrate (R:C) ratios on dry matter consumption and residual feed intake, globular volume in blood, eggs per gram of feces and methane emission in lambs artificially infected with Haemonchus contortus. A completely randomized design was used in a 4 x 2 factorial scheme (four diets ? 70:30, 66:34, 43:57, 36:54 R:C ratios), infected or not with Haemonchus contortus. Thirty-two male lambs, with an average initial weight of 26.6 kg and five months of age, were used. Data were submitted to statistical analysis and compared by Tukey test, at a 5% significance level. The increase in the proportions of dietary CP and TDN resulted in improved feed efficiency, performance, resilience to Haemonchus contortus and mitigation of enteric methane emissions. Diets with 66 and 43% R:C ratios with CP and TDN values ??of 11 and 63% and 13.94 and 70%, respectively, are recommended. Diets with a higher intake of protein and energy associated, with at least 66% of roughage, can guarantee better results considering the parameters evaluated.
