“…It is also due to variables existing in the field and not present in controlled condition studies, like fruit in different stages and physiological conditions (6). However, knowledge of infection and colonization processes of Colletotrichum spp., as well as of the factors that influence such processes, is a pre-requisite for the development of effective control strategies, like a warning system based on weather conditions (10).…”

307The guava fruit (Psidium guajava L.) is an excellent source of vitamins A, B and C, as well as of calcium, zinc, phosphorus and iron. Red guava can be used for fresh consumption and by the agricultural industry, and 'Pedro Sato' is one of the most important cultivars in Brazil (16,28). White guava is used for fresh consumption, and 'Kumagai' is the main cultivar exported from Brazil (15). RESUMOPalavras-chave adicionais: Psidium guajava, incidência, severidade, período de incubação, período de latência, 'Kumagai', 'Pedro Sato'.O desenvolvimento de muitas doenças pós-colheita está intimamente associado ao amadurecimento dos frutos. As condições ambientais podem afetar tanto o desenvolvimento do patógeno quanto a taxa de amadurecimento dos frutos. O objetivo deste trabalho foi determinar as condições de temperatura e duração do período de molhamento mais favoráveis ao desenvolvimento da antracnose em frutos de goiaba. Frutos de goiaba das cultivares Kumagai (polpa branca) e Pedro Sato (polpa vermelha) destacadas foram inoculadas com suspensão de conídios de Colletotrichum gloeosporioides e C. acutatum e incubados sob temperaturas constantes variando entre 10 e 35ºC e molhamento contínuo de 6 e 24 horas. A severidade e incidência da doença foram avaliadas a cada dois dias durante 12 dias. Não houve infecção nas temperaturas de 10 e 35ºC, independentemente do período de molhamento. As condições ótimas Soares-Colletti, A.R.; Lourenço, S.A. Efeito da temperatura, duração do molhamento e cultivares na anctrose em fruto da goiaba. Summa Phytopathologica, v.40, n.4, p.307-312, 2014. para a infecção do fruto foram sob temperatura de 26 e 27ºC, para 'Kumagai' e de 25 e 26ºC, para 'Pedro Sato', com 24 horas de molhamento. De um modo geral, o desenvolvimento da doença na cultivar Kumagai foi mais afetado pela duração do período de molhamento, comparada com a 'Pedro Sato'. A severidade máxima da doença em frutos ocorreu entre 25 e 30ºC, dependendo da espécie de Colletotrichum, para 'Kumagai'. Para 'Pedro Sato' o diâmetro médio das lesões foi maior em frutos armazenados a 20, 25 e 30ºC do que na cultivar Kumagai, dependendo do período de molhamento e espécie. O período de incubação (6 e 7 dias) e o período de latência (8 e 10 dias) foram mínimos à 30ºC. Estas informações geradas nesse trabalho serão úteis tanto para o desenvolvimento de sistemas de aviso fitossanitário quanto para aumentar o tempo de vida de goiabas após a colheita. Effect of temperature, wetness duration and cultivar on the development of anthracnose in guava fruitsAna Raquel Soares-Colletti 1 , Silvia Brazil is the world's largest producer of red guavas and the second producer of white guava. Despite its great production, Brazil is an insignificant exporter of guava in natura due mainly to the high perishability of the fruit in the postharvest (23,14). Guava has a shelf life that can reach 3 to 5 days at room temperature. Postharvest damages, including postharvest diseases, are estimated at 20 to 40% (24, 8).The development of a large number of postha...

“…The former are members of the SECC research team while the latter are engaged through planned outreach, including monthly video conferences, one-on-one meetings, training workshops to gain confidence in climate decision tool use and to identify opportunities for their application, and traditional extension activities (e.g., commodity meetings, field days) (Fraisse et al 2005). SECC leverages the trust engendered by Cooperative Extension's long service to the agricultural community and its access to local knowledge and experience to build support for its AgClimate online decision-support tool (available online at http://www.agclimate.org; see Fraisse et al 2006). Direct engagement with stakeholders provides feedback to improve the design of the tool and to enhance climate forecast communication (Breuer et al 2007).…”

Moving from climate science to adaptive action is an immense challenge, especially in highly institutionalized sectors such as water resources. Knowledge networks are valuable strategies to put climate information to use. They overcome barriers to information adoption such as stovepipes, pipelines, and restricted decision space, and they can be responsive to issues of salience and the hurdles of reliability, credibility, and trust. Collaboration and adaptive management efforts among resource managers and forecast producers with differing missions show that mutual learning informed by climate information can occur among scientists of different disciplinary backgrounds and between scientists and water managers. The authors show how, through construction of knowledge networks and their institutionalization through boundary organizations focused on salient problems, climate information can positively affect water resources decision making.

“…Thus, it is difficult to determine the in-field effects of irrigation management strategies including adoption of PI technologies on crop yield and other soil management practices. In contrast, the use of crop simulation models in crop production, irrigation management and climate change impacts has proven to be invaluable in improving knowledge of the functioning of agricultural systems (Casadesús et al 2012;Fraisse et al 2006;Thorp et al 2008). In this context, the Food and Agriculture Organization (FAO) has developed AquaCrop ), a crop water productivity model focused on simulating water-limited attainable crop yield.…”

Modelling impacts of precision irrigation on crop yield and in-field water management

et al. 2017

Precision irrigation technologies are being widely promoted to resolve challenges regarding improving crop productivity under conditions of increasing water scarcity. In this paper, the development of an integrated modelling approach involving the coupling of a water application model with a biophysical crop simulation model (Aquacrop) to evaluate the in-field impacts of precision irrigation on crop yield and soil water management is described. The approach allows for a comparison between conventional irrigation management practices against a range of alternate so-called 'precision irrigation' strategies (including variable rate irrigation, VRI). It also provides a valuable framework to evaluate the agronomic (yield), water resource (irrigation use and water efficiency), energy (consumption, costs, footprint) and environmental (nitrate leaching, drainage) impacts under contrasting irrigation management scenarios. The approach offers scope for including feedback loops to help define appropriate irrigation management zones and refine application depths accordingly for scheduling irrigation. The methodology was applied to a case study in eastern England to demonstrate the utility of the framework and the impacts of precision irrigation in a humid climate on a high-value field crop (onions). For the case study, the simulations showed how VRI is a potentially useful approach for irrigation management even in a humid environment to save water and reduce deep percolation losses (drainage). It also helped to increase crop yield due to improved control of soil water in the root zone, especially during a dry season.
