The forage use in animal production is functional and can be consider a strongly feed resource in the Brazilian livestock systems. Since grazing management has been studied, the understanding of organic reserves in forage plants is a challenge. The regrowth speed and longevity are function of recovery plant capacity after defoliation, what is highly influenced by harvest management. The objective with this study was to evaluate tussocks density, root and stubble mass Panicum maximum BRS Quenia and BRS Tamani. Pastures were submitted to intermittent grazing (95% of light interception) with two grazing intensities defined by postgrazing height: 20 and 35 cm for Quenia, and 15 and 25 cm for Tamani. The experiment was carried out at Embrapa Agrossilvipastoril, Sinop/MT, from March/15 to Dez/16, following a randomized complete block design, with tree replications. During the spring of 2016, after grazing, 3 tussocks were collect per experimental unit. Each tussock was fractionated in stubble (above soil) and root, washed and dried at 105 ° C for 1.5 hours and later at 55° for 72 hours. The tussocks quantification was done in 10 points per plot, using a frame of 1m². The data was analyzed using PROC MIXED of SAS statistical software. Treatments means were estimated by ?LSMEANS? compared by the probability of the difference (?pdiff?) at 5%. There is no cultivar and grazing intensity for root and stubble mass, and tussock density (P>0.05). Root mass was 1590 and 1915 kg ha-1 for Quenia and Tamani, respectively. The tussock density was, an average, 6.9 tussocks m-2, for both cultivars. Under lower intensity, the root and stubble mass were 1826 and 1293 kg ha-1, respectively. It did not differ in pastures under higher intensity, where 1683 and 1747 kg ha-1 were registered. Thus, Quenia and Tamani have well regrowth potential under different grazing intensity. The trigger for define the grazing end point for Tamani should be from 25 to 15 cm, and for Quenia from 35 to 20 cm,respectively.

A mandioca (Manihot esculenta Cranz) é um dos alimentos mais consumidos no mundo sendo fonte de carboidrato, notadamente, para populações de baixa renda. A identificação de genótipos mandioca se faz necessário a fim de evitar a duplicidade em bancos e coleções de germoplasma e resolver conflitos quanto à nomenclatura distinta atribuída às variedades iguais no campo. O objetivo deste trabalho foi demonstrar através de marcadores botânicos, agronômicos e moleculares a duplicidade genética existente de quatro principais variedades de mandioca cultivadas por agricultores familiares no Acre. O trabalho de campo foi desenvolvido no Campo Experimental da Embrapa Acre situado em Rio Branco e no Polo Agroflorestal de Xapuri durante a safra de 2018/19 onde foram avaliados 30 descritores botânicos e agronômicos de quatro variedades locais de mandioca mais cultivadas no Acre como: BRS Ribeirinha, Caboquinha, Paxiubão e Pirarucu. As análises moleculares foram realizadas marcadores microssatélites. Os resultados das avaliações de campo e moleculares permitiram concluir que as variedades são redundantes entre si. Cassava (Manihot esculentaCranz) is one of the most consumed foods in the world and is a source of carbohydrate, especially for low-income populations. The identification of cassava genotypes is necessary in order to avoid duplication in germplasm banks and collections and to resolve conflicts over the distinct nomenclature attributed to the same varieties in the field. The objective of this work was to demonstrate through botanical, agronomic and molecular markers the existing genetic duplicity of four main cassava varieties cultivated by family farmers in Acre. The fieldwork was carried out at the Embrapa Acre Experimental Field in Rio Branco and at the Xapuri Agroforestry Complex during the 2018/19 harvest, where 30 botanical and agronomic descriptors of four local cultivated cassava varieties in Acre were evaluated as: BRS Riverside, Caboquinha, Paxiubão and Pirarucu. Molecular analyzes were performed microsatellite markers. The results of field and molecular evaluations led to the conclusion that the varieties are redundant with each other.
