ABSTRACT.
Knowledge about contributing factors to yield loss is essential for sustainable intensification of agriculture, which has the objective to increase both, yield and environmental sustainability. This study aimed to identify strategies to reduce the distance between under-performing and best-yielding greenhouse tomato crops in the south region of Uruguay. Gap to attainable yield was described and main causes of yield variability were explored by combining regional agronomic diagnosis and yield gap analysis. A sample of 110 tomato greenhouses within 23 farms during 2014/15 and 2015/16 were assessed. The variables assessed were classified in four
groups: growth defining, growth limiting, growth reducing factors and yield components. Yield ranged from 0.9 to 24.3 kg m−2. Cumulated photosynthetically active radiation (PAR) intercepted was the most correlated with yield. We analyzed two complementary ways of increasing yield: (1) modifying growth-defining factors to increase cumulated PAR intercepted and attainable yield, and (2) modifying growth-limiting and reducing factors responsible for the gap to attainable yield at a given level of cumulated PAR. PAR interception could be increased by adjusting transplanting dates to modify daily incident radiation, improving transmissivity of greenhouses and fraction PAR intercepted by canopy. We classified crops in three groups of cumulated PAR intercepted and yield. The average gap between actual and attainable yield was 34%. The strategy to close that gap differed among groups, but K nutrition was common to all. Results from this study allowed us to deliver relevant and actionable information to better inform discussions among farmers and their technical advisors.

SUMMARY.
Several Diaporthe species are recognized as causal agents of many plant disease symptoms, including twig and branch cankers, dieback, shoot blight, and root and fruit rots. In Uruguay, the proximity between apple, pear and peach orchards offers the possibility to study the presence of different Diaporthe spp. associated with
wood cankers across different deciduous fruit trees. Symptomatic twigs and branches of these orchard species were sampled, and isolates of Diaporthe were obtained. Selected isolates were used for cross inoculations in the three hosts. Seven Diaporthe spp. were identified, based on the internal transcribed spacer (ITS) region of rDNA and the translation elongation factor 1-alpha gene (EF1-α) phylogenies. The species were: Diaporthe amygdali, D. foeniculina, D. infecunda, D. eres, D. terebinthifolii, D. oxe and D. phaseolorum, while two isolates Diaporthe sp. 1 and Diaporthe sp. 4 could not be assigned to any species. Diaporthe infecunda, D. eres, D. terebinthifolii, D. phaseolorum and D. oxe on Pyrus communis and D. foeniculina on Malus domestica represent new records in these hosts in Uruguay, while D. oxe isolated from Prunus persica is a new record for this species. Diaporthe eres and D. phaseolorum were the most virulent species, posing the greatest risk due to their wide distribution and virulence in apple and peach trees. Although pear trees showed less symptomatic tissues and were less susceptible than peach and apple trees in the pathogenicity tests, they harboured seven of the species, and therefore should be considered as reservoirs of Diaporthe in Uruguayan orchards. Trees of the three hosts could be considered potential reciprocal sources of pathogenic Diaporthe spp.
