“…The hemicellulose content in the stems of plants fertilized with Super N in the first cut was lower compared to the plants fertilized with other nutrient sources. Lower values of ADF (cellulose and lignin) and hemicellulose were observed with the use of nitrogenous fertilizers, which concurs with results reported by Costa et al (2009).…”

Several fertilizers with different efficiency and price are commercially available to increase the yield of pastures, generating doubts about which should be chosen for fertilization, especially regarding short term operation returns. Our objective was to investigate the effect of simple and compound fertilizers on the production, chemical composition and economic parameters of Marandu and Xaraes palisade grass in the short term. The fertilizers Urea, Super N, were evaluated in three cuts of the pasture. The overall rate of tiller occurrence, dry matter production, crude protein content, total digestible nutrients and digestible energy of Marandu palisade grass increased with the supply of nitrogenous fertilizers, while neutral detergent fiber (NDF), acid detergent fiber and hemicellulose content decreased. Fertilization using Super N resulted in higher production of mass per kilogram of fertilizer applied and per unit of real (R$) invested per hectare. The number of tillers of Xaraes palisade grass increased and NDF content decreased with the application of 20-10-10. Fertilization of Marandu palisade grass with Super N is more efficient from the economic and productive point of view than fertilization with urea. Comparing the grasses, Xaraes is more demanding in phosphorus and potassium than Marandu.Key words: chemical composition; morphological characteristics; production cost.

“…Stem dry mass production in the third cut of Marandu palisadegrass fertilized with Super N was greater than two first cuts, which can be attributed to the gradual liberation of N in the soil solution (Table 1). Costa et al (2009) verified linear increases of dry mass production of Marandu palisadegrass due to N supply.…”

“…A high N accumulation by itself is already a desirable characteristic, once the N on the plant remains protected of loss processes and might be more efficiently recycled on the system. This may reduce the production costs, avoid natural resources degradation and increase the crops yield (Costa et al, 2009). Besides, the N has an important function in structural characteristics of the plants, which could positively influence the Brachiaria's production (Silva et al, 2013) and improve the management when this forage is used to animal production.…”

Under certain circumstances species of the Brachiaria genus, particularly B. humidicola might be able to suppress the biological nitrification in soil. This study aimed to investigate the ability of four Brachiaria species cultivated in Brazil to promote changes in the N dynamics in the soil as well as its capacity in use efficiently N under low N availability. In a greenhouse condition and using a Quartzipsamment soil, four species of Brachiaria (B. brizantha, B. decumbens, B. humidicola and B. ruziziensis) and two cut managements ("single cut" -performed at 140 days after seeding (DAS) and "cut/regrowth"-performed at 55 DAS and 85 days after the first cut (140 DAS)), plus a control treatment containing only soil were compared in a factorial design (4×2+1). The following evaluations were performed in plants: dry matter of shoots and roots, total N content, N accumulated and N use efficiency; and soil (which was split in rhizospheric and non-rhizospheric): ammonium, nitrate and total-N contents and pH value. Based on the soil inorganic-N content, there was no detectable effect of species in the soil nitrification process. Moreover, the highest ability of uptaking and using the N was observed in B. humidicola, which in the "single cut" management proved to be able to produce 201 g of shoot dry matter in response to each 1 g of N accumulated.

“…De acordo com Miranda et al (1999), o estilosantes 'Campo Grande' pode fixar de 88 a 180 kg ha -1 ano -1 de nitrogênio. Costa et al (2008Costa et al ( e 2009a verificaram aumento de 65, 78 e 77 % nas concentrações de nitrogênio em cultivares de Brachiaria brizantha ('MG-4', 'Marandu' e 'Xaraés') em resposta às doses de nitrogênio.…”
