“…The studies published so far focus on vegetables (Vilela Júnior et al, 2003;Santos et al, 2012;Sediyama et al, 2009; or pasture (Orrico Júnior et al, 2012), but few field studies addressed pig slurry biofertilization of cereals such as corn.…”

Organic materials subjected to a process of anaerobic digestion in a digester produce biofertilizer that can be used in agriculture as nutrient source. The objective of this study was to evaluate the effect of pig slurry biofertilizer on soil chemical properties and on corn yield and nutrient concentrations in leaves and kernels. The experiment was conducted in the field from November 2012 to April 2013, and was arranged in a randomized block design with seven treatments and four replicates. The treatments consisted of doses of pig slurry biofertilizer (0; 40; 80; 120; 160; 200 and 240 m3 ha-1), applied to the soil surface in a single application, at stage V2 of corn plants. Thirty-three days after biofertilization, soil samples were collected in each plot. Corn was harvested 129 days after sowing. Doses up to 240 m3 ha-1 of pig slurry biofertilizer applied to soil with good fertility did not influence soil chemical properties and corn yield. The use of pig slurry biofertilizer had no detectable effect on nutrient concentrations in corn leaves and kernels.

“…The seasonal periods of the year interfered in the productive responses of BRS Kurumi regarding the doses of nitrogen and heights of residue tested (Figure 2 and Table 1). Tropical grasses show low productive performance during the dry period (autumn and winter), and this productive seasonality is more evident in the south-central region of Brazil (ARAUJO et al 2018;ORRICO JUnIOR et al 2012;ORRICO JUnIOR et al 2013). The decrease in biomass production during the dry period is due to the low air temperature and rainfall, and shorter photoperiod, which are characteristics of the dry period (Figure 1).…”

The objective was to evaluate the effect of nitrogen fertilization levels on productivity, and nutritional value of BRS Kurumi managed at different residue heights during rainy and dry periods of the year. The pasture was managed in three residue heights (20, 35, and 50 cm) and three nitrogen fertilization levels (0, 100, and 200 kg N/ha/year) during the rainy and dry seasons. When the height of the grass of each plot reached 80 cm, the Kurumi was cut manually at the pre-established residue heights. Around 89% of the dry matter (DM) production was observed during the rainy season. The residue height of 35 cm together with doses of 100 or 200 kg N/ha/year, and the residue height of 20 cm, with a dose of 100 kg N/ha/year were the treatments that had the highest DM production during the rainy period. No differences in DM production were observed between tested treatments during the dry period. The Kurumi cultivated during the dry period had the highest content of neutral detergent fiber and lowest digestibility. The Kurumi managed with residue heights of 20 and 35 cm and fertilized with 100 kg N/ha had the highest values of efficiency of utilization applied nitrogen. The use of 20 or 35 cm of residue height and 100 kg of N/ha/year is recommended to obtain greater biomass production and nutrients, nutritional quality, and nitrogen use efficiency.

“…No capim Tifton 85, Erthal et al (2010) verificaram que a aplicação de água residuária de bovinocultura resultou em maior acúmulo de forragem com maiores concentrações de proteína bruta. Resultados semelhantes foram observados no capim-piatã adubado com diferentes doses de biofertilizante, com aumento linear no acúmulo forragem, além de melhorias no valor nutritivo (ORRICO JUNIOR et al, 2012;ORRICO JUNIOR et al, 2013).…”

A adubação orgânica pode ser utilizada de forma sustentável visando o fornecimento de nutrientes as plantas. No entanto, são restritas as informações referentes às doses a serem aplicadas. Objetivou-se avaliar o desenvolvimento e valor nutritivo de capim-piatã recebendo diferentes níveis de biofertilizante (0, 1,0, 2,0, 3,0 e 4,0 L de biofertilizante líquido de esterco bovino por vaso) e diferentes condições de adubação química (dose zero – controle, com aplicação de 50 e 100% da recomendação de adubação química). O biofertilizante associado ou não com adubação química proporcionou aumentos na massa de forragem, massa de raiz e altura final das plantas e redução da razão parte aérea:raiz. A concentração proteína bruta foi influenciada pelos níveis de biofertilizante aplicado, na ausência de adubação química. As concentrações de fibra em detergente neutro e fibra em detergente ácido responderam de forma quadrática aos níveis de biofertilizante utilizado, quando foram associadas a 100% da dose recomendada de adubação química. Quando 50% da recomendação adubação química foi utilizada a fibra em detergente ácido aumentou linearmente. A utilização de biofertilizante pode ser uma alternativa promissora em substituição total ou parcial da adubação química, melhorando o desenvolvimento e valor nutritivo do capim- piatã na implantação.Palavras-chave: biofertilização; Brachiaria brizantha cv.

PRODUCTION AND NUTRITIVE VALUE OF PIATÃ PALISADE GRASS SUBMITTEDTO ORGANIC AND CHEMICAL FERTILIZATION ABSTRACT: Organic fertilization can be used sustainably in providing nutrients to plants. However, information regarding the doses to be applied is restricted. The objective was to evaluate the development and nutritional value of piatã palisade grass receiving different levels of biofertilizer (0, 1.0, 2.0, 3.0 and 4.0 L of liquid bovine manure biofertilizer) and different conditions of chemical fertilization (zero dose - control, applying 50 and 100% of the chemical fertilization recommendation). The biofertilizer associated or not with chemical fertilization provided increases in forage mass, root mass and final plant height and reduced shoot: root ratio. The crude protein concentration was influenced by the levels of biofertilizer applied in the absence of chemical fertilization. The concentrations of neutral detergent fiber and acid detergent fiber concentrations responded quadratically to the levels of biofertilizer used, when they were associated with 100% of the recommended chemical fertilizer dose. When 50% of the chemical fertilizer recommendation was used the acid detergent fiber increased linearly. The use of biofertilizer can be a promising alternative in total or partial substitution of chemical fertilization, improving the development and nutritional value of the piatã palisade grass at implantation.Keywords: biofertilization; Brachiaria brizantha cv.
