Rapeseed (Brassica napus L.) is the second most produced oilseed crop in the world. It provides a high-quality nutrient for pollinating insects, and pollination, in many cases, increases crop yield. Although a large number of species visit rapeseed crops, Apis mellifera (Hymenoptera: Apidae) is the most frequent, abundant, and with the highest pollination potential. Our aim was to evaluate the effect of A.mellifera on the different yield components of Brassica napusL. (cv. Rivette). The hypothesis of the study was that the presence of pollinators would increase rapeseed crop yield and improves maturation uniformity. Four trials were conducted (one in 2013, two in 2015, and one in 2016) in commercial rapeseed crops, using pollinator exclusion tents placed during the flowering period. A randomized complete block design with two treatments and six replications during 2013 and three replications during 2015 and 2016 was used. Treatments consisted of exclusion tents with the addition of an active beehive (WITH) and without a beehive (EXCLUDED). WITH treatments showed greater uniformity on siliques maturation and a lower proportion of flowers at maturity. Rapeseed yield was determined by the site (season and farm) (P < 0.0005) and treatments (WITH or EXCLUDED) (P = 0.0482), with no interaction between them (P = 0.1217). Grain yield in WITH treatments was 14% higher than in EXCLUDED treatments (2089 vs. 1836 kg ha?1). In 12 out of 15 (80%) experimental units, WITH treatment yields were higher than EXCLUDED treatments. Results show that A.mellifera can increase rapeseed yields, despite a high rate of self-fertilization.

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.
