Abstract: Rice is an important source of methane (CH4) and other crops may be sources of nitrous oxide (N2O), both of which are powerful greenhouse gases. In Uruguay, irrigated rice rotates with perennial pastures and allows high productivity and low environmental impact. A long-term experiment with contrasting rice rotation intensification alternatives, including rice?soybean and continuous rice, was recently carried out in an Argialboll located in a temperate region of South America. To know if rotation systems influence soil microbial activity involved in CH4 and N2O emissions, the abundance and potential rate for gas production or consumption of microbial populations were measured during the rice crop season. CH4 was only emitted when rice was flooded and N2O emission was not detected. All rotational soils showed the highest rate for methanogenesis at tillering (30 days after rice emergence), while for methanotrophy, the maximum rate was reached at flowering. The abundance of related genes also followed a seasonal pattern with highest densities of mcrA genes being observed at rice flowering whereas pmoA genes were more abundant in dry soils after rice harvest, regardless of the rotation system. Differences were found mainly at tillering when soils with two consecutive summers under rice showed higher amounts of mcrA and pmoA gene copies. The potential denitrification rate was highest at the tillering stage, but the abundance of nirK and nirS genes was highest in winter. Regarding ammonium oxidation, bacterial amoA abundance was higher in winter while the archaeal amoA gene was similar throughout the year. A strong influence of the rice growth stage was registered for most of the parameters measured in rice paddy soils in this no-till rice intensification experiment. However, differences among rotations begin to be observed mainly at tillering when the abundance of populations of the methane and nitrous oxide cycles seemed to respond to the rice intensification.

ABSTRACT.
In Uruguay, the production of tomato (Solanum lycopersicum) in greenhouse presents pollination issues that limit its yield. The use of bumblebees (Bombus spp.) as pollinators can help overcome this problem as they perform ?buzzing pollination?, a behavior that makes them excellent pollinators of Solanaceae and particularly tomato. The aim of this study was to evaluate the effect of the native bumblebees Bombus atratus on the pro-portion of fruit set, weight, diameter, number of seeds and number of locules of tomato (LAPATAIA and ELPIDAvarieties). An experience was carried out in Canelones, where the fruits from flowers pollinated by bumblebees and from flowers not visited by insects were compared; two other experiences carried out in Salto were similar to that of Canelones, but included flowers treated with hormones. In the three analyzed greenhouses the visit of bumblebees to the flowers increased the proportion of fruit set by 13 - 47%, compared to the result obtained in flowers not visited by the insects. Also, the pollinating action of bumblebees significantly improved the weight, size, and number of seeds compared to fruits obtained from flowers without access to pollinators. This improve-ment was recorded in the experience in Canelones and only in one of the Salto's experiences. On the other hand, a positive correlation was found between the number of seeds and the weight (R2 = 0.37, R2 = 0.53; LAPATAIA, ELPIDA, respectively) in the two tomato varieties. This study is the first in Uruguay to show the benefits of using native bumblebees in tomato production in greenhouses.
RESUMEN.
En Uruguay, la producción de tomate (Solanum lycopersicum) bajo invernáculo presenta problemas de polini-zación que limitan su rendimiento. El uso de abejorros (Bombus spp.) como polinizadores puede contribuir a superar este problema, ya que realizan «polinización por zumbido», comportamiento necesario para polinizar las solanáceas y particularmente el tomate. El objetivo de este estudio fue evaluar el efecto de los abejorros nativos Bombus atratus en el porcentaje de cuajado, peso, diámetro, número de semillas y número de lóculos de tomate (variedades LAPATAIA y ELPIDA). Se realizó una experiencia en el departamento de Canelones donde se cotejaron los frutos de flores polinizadas por abejorros y flores no visitadas por los insectos; y dos experien-cias en Salto iguales a la de Canelones, pero que incluían flores tratadas con hormonas. En los tres invernáculos la visita de los abejorros a las flores incrementó el porcentaje de cuajado entre 13 y 47 % en relación con el obtenido en flores no visitadas por los insectos. La acción polinizadora de los abejorros también mejoró signifi-cativamente el peso, tamaño y número de semillas respecto a frutos obtenidos de flores sin acceso a poliniza-dores en dos de las tres experiencias realizadas. Por otro lado, en las dos variedades de tomate se encontró una correlación positiva entre el número de semillas y el peso (R2=0,37, R2=0,53; LAPATAIA, ELPIDA, respectiva-mente). Este estudio es el primero en Uruguay que muestra los beneficios de utilizar abejorros nativos para mejorar la producción de tomates en invernáculos.
RESUMO.
No Uruguai, a produção de tomate (Solanum lycopersicum)em estufas apresenta problemas de polinização que limitam sua produção. O uso de abelhas (Bombus spp.) como os polinizadores podem contribuir para su-perar esse problema, uma vez que realizam a "polinização por zumbido", um comportamento necessário para polinizar as máscaras e principalmente o tomate. O objetivo deste estudo foi avaliar o efeito da abelha nativa Bombus atratus (abelhão) sobre a porcentagem de frutos, peso, diâmetro, número de sementes e número de lóculos de tomate (variedades LAPATAIA e ELPIDA). Foi realizada uma experiência no departamento de Canelo-nes, onde foram coletados os frutos de flores polinizadas por abelhas e as flores não visitadas por insetos; e duas experiências em Salto iguais às de Canelones, mas que incluíam flores tratadas com hormônios. Nas três estufas, a visita das abelhas às flores aumentou o conjunto de frutos entre 13 e 47% em relação ao obtido em flores não visitadas pelos insetos. A ação polinizadora das abelhas também melhorou significativamente o peso,tamanho e número de sementes em comparação aos frutos obtidos de flores sem acesso aos polinizadores em duas das três experiências realizadas.
