A bananeira é uma importante fruteira nas regiões produtoras, pois contribui com o desenvolvimento socioeconômico através da geração de emprego e renda. Sua fruta está entre as mais consumidas do mundo, no Brasil e no estado do Acre. O objetivo deste estudo foi avaliar o crescimento e rendimento de bananeira, cv. D?angola, em consórcio com açaizeiro (Euterpe precatoria) nas condições de clima e solo do Acre. O experimento foi instalado e conduzido no campo experimental da Embrapa Acre, utilizando-se delineamento em blocos casualizados completos com cinco tratamentos, quatro repetições e oito plantas por parcela. Os tratamentos foram assim dispostos: T1 - Bananeira em 3 x 3 m; T2 - Bananeira (3 x 2 m) com açaizeiro (3 x 4 m); T3 - Bananeira (3 x 3 m) com açaizeiro (3 x 4 m); T4 - Bananeira (4 x 2 x 2 m) com açaizeiro (6 x 3 m); e T5 ? Bananeira (4 x 2 x 2 m) com açaizeiro (4 x 2 x 3 m). A cada dois meses foi avaliado a altura, o perímetro do pseudocaule e o número de folhas até a emissão floral. O rendimento também foi avaliado. As características de crescimento de bananeira, cv. D?angola, não sofre interferência dos sistemas de plantio e espaçamentos até a densidade de 1.666 plantas ha-1. As maiores densidades de plantio de bananeiras promovem rendimentos superiores tanto em monocultivo quanto em consórcio com açaizeiro. The banana tree is an important fruit tree in the producing regions, as it contributes to the socioeconomic development through the generation of employment and income. Its fruit is among the most consumed in the world, in Brazil and in the state of Acre. The objective of this study was to evaluate the growth and yield of banana, cv. D'angola, in a consortium with açaizeiro (Euterpe precatoria) in the climate and soil conditions of Acre. The experiment was installed and conducted in the experimental field of Embrapa Acre, using a randomized complete block design with five treatments, four replications and eight plants per plot. The treatments were thus arranged: T1 - Banana tree in 3 x 3 m; T2 - Banana tree (3 x 2 m) with assai (3 x 4 m); T3 - Banana tree (3 x 3 m) with assai (3 x 4 m); T4 - Banana tree (4 x 2 x 2 m) with assai (6 x 3 m); and T5 - Banana tree (4 x 2 x 2 m) with assai (4 x 2 x 3 m). Every two months the height, the perimeter of the pseudocaule and the number of leaves were evaluated until the floral emission. Yield was also evaluated. The growth characteristics of banana, cv. D'angola, does not suffer interference from planting systems and spacing up to the density of 1.666 plants ha-1. The higher planting densities of banana plantations promote higher yields both in monoculture and in a consortium with açaizeiro.

Although agriculture and livestock systems represent important sources of N2O from the soil, they may also aid in emissions mitigation, mainly when integrated systems are taken into account, such as crop-livestock-forest, for food production. This work assessed the soil N2O emissions from a tropical Oxisol under row-crop, livestock, forest monocultures, and an integrated crop-livestock-forest system in the Southern Amazon - Brazil. Soil N2O emissions were measured using static chambers from November 2014 to October 2016 in four soil use systems [row-crop, livestock, forest, and integrated crop-livestock-forest (CLF)], and in a reference area under native forest fragment. For the whole period, the average of soil N2O fluxes was 16.9, 12.2, and 15.4 ug N2O-N m-2 h-1, to row-crop, livestock, and CLF systems, respectively, all with a similar average among them. The lowest fluxes were observed in the forest system and native forest fragment, with average fluxes of 4.0 and 6.3 ug N2O-N m-2 h-1, respectively, both lower than the agricultural systems. The largest soil N2O fluxes were observed throughout the rainy seasons in the row-crop, livestock, and CLF, mostly after N-fertilizer application to the soil surface or in the planted row. As a consequence, the cumulative emissions were greater in row-crop, livestock, and CLF systems, which in the averages of two cycles emitted respectively 1.40, 1.15, and 1.27 kg N2O-N ha-1 yr-1, all different of the forest system and native forest fragment (0.33 and 0.52 kg N2O-N ha-1 yr-1, respectively). Nitrogen fertilization and soil moisture influenced soil N2O emissions of all systems assessed in the Southern Amazon. The N2O emissions took place after both factors were met, corroborating the hole-in-the-pipe model. Even with more soil use intensification, once in the same area there were three cultures in succession during a year and perennial trees, CLF did not lead to greater N2O emissions from the soil than row-crop and livestock. Thus, CLF represents a good option for N2O mitigation for the edaphic and climatic conditions of the Southern Amazon.
