ABSTRACT: In semiarid agricultural systems, irrigation may increase soil organic matter (SOM) due to higher biomass
production. However, aboveground production tends to increase more than belowground biomass, and in no-till
systems SOM responses to irrigation would strongly depend on the fate of crop residues left on the soil surface.
Litter decomposition and SOM formation can also be affected by irrigation due to changes in water dynamics, but
little is known about the impacts of irrigation on the pathways of SOM formation. We used dual 13C and 15N
labeled maize litter to quantify the effect of irrigation on the contribution of aboveground crop residues to SOM
formation in semiarid, no-till agricultural systems. We incubated the litter in a continuous maize cropping system
with two treatments, dryland and irrigated, and measured litter decomposition and its contribution to different
SOM pools. Irrigation had a larger effect on litter C and N losses than on the formation of new SOM. After 13
months the C and N losses from the litter layer were 24% higher under irrigation, but there were no treatment
differences in the litter-derived C and N recovered in SOM. Most of the litter-derived organic matter (OM) was
found in the mineral associated OM pool (MAOM), but irrigation did not affect the amount of litter-derived OM
found as MAOM or as particulate organic matter. Irrigation increased the amount of litter-derived OM found in
macroaggregates, and this observation was more related to a higher aggregation than to aggregate enrichment in
the irrigated treatment. Our results suggest that a smaller proportion of aboveground crop residues will form
SOM in irrigated systems compared to dryland conditions and may help to partially explain why irrigation has a
stronger relative effect on crop productivity and C inputs than on SOC stocks in semiarid agricultural systems. MenosABSTRACT: In semiarid agricultural systems, irrigation may increase soil organic matter (SOM) due to higher biomass

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. Por outro lado, nas duas variedades de tomate, foi encontrada uma
correlação positiva entre o número de sementes e o peso (R2 = 0,37, R2 = 0,53; LAPATAIA, ELPIDA, respectiva-mente). Este estudo é o primeiro no Uruguai a mostrar os benefícios do uso de abelhas nativas para melhorar a produção de tomate em estufas. MenosABSTRACT.
