“…The number of tillers was within the range of 430 m -2 in the treatment without mineral N in the first cutting, and 965 m -2 in the treatment with Azospirillum in the third cutting, both in the second year. Similar results have been verified in studies testing N fertilization in 'Marandu' palisade grass during the summer (Pedreira et al, 2017;Silva, Costa, Faquin, Oliveira, & Bernardes, 2013). The lack of tiller number response to N fertilization in the second and third cuttings, and accumulated cuttings as well, may be associated with sufficient N supply from the mineralization of soil organic matter.…”

“…palisade grass production and development (Pedreira et al, 2017), but the inoculation with Azospirillum brasiliense strains Ab-V5 and Ab-V6 did not result in increased tiller numbers (Table 1) Tiller response to N fertilization was only verified in the first cut in both years, while shoot dry mass increased only in the first cut of the second year. The number of tillers was within the range of 430 m -2 in the treatment without mineral N in the first cutting, and 965 m -2 in the treatment with Azospirillum in the third cutting, both in the second year.…”

“…As an alternative to intense tiller death caused by pasture, inoculation with A. brasilense emerges as a strategy to increase tillering in tropical grass under pasture conditions. Although Pedreira et al (2017) did not observe an increase in tillering when inoculating in brachiaria grass (Urochloa brizantha cv. Marandu), in the present study, there was a significant increase as a function of inoculation for all doses of N, except in the absence of N.…”

“…The good development of forage roots becomes very interesting in countries such as Brazil, which has a very expressive drought during the year (Pedreira et al, 2017) that reduces the production of pastures.…”
