“…This germplasm originated from Brazil, one of the top ten producers of onion in the world [28]. The pedigree of 'Baia Periforme' indicated that it is part of a Portuguese introduction 'Garrafal' [28]. Starting from the 1970s, 'Baia Periforme' germplasm was heavily used by the onion breeding program of the Agronomic Institute of Pernambuco, Brazil, for selecting several varieties with superior breeding traits, such as high temperature adaptation, bulb yield, earliness, and tolerance to major biotic stresses [28].…”

Good bulb production of this accession in the research fields of New Mexico is due to the fact that it is well adopted into the irrigated agricultural practices of the semi-arid regions of Northeast Brazil [28].…”

Fusarium basal rot (FBR) caused by Fusarium oxysporum f. sp. cepae (FOC) is a major threat to onion (Allium cepa L.) production and marketing worldwide. Finding new sources of FBR-resistance to develop synthetic cultivars is a priority for onion breeders. As there are no FBR-resistant short-day onion cultivars, 85 U.S. National Plant Germplasm System plant introduction onion accessions that originated from 23 different countries were screened for their FBR susceptibility. To compare FBR susceptibility of these accessions at their seedling and mature bulb stages, a susceptible check cultivar, NuMex Crimson, a partially resistant check cultivar, Serrana and its selected population, Serrana-sel, were included in the study. The seedling screening was performed after inoculating silica-sand media with a virulent FOC isolate ‘CSC-515’ at 1.0 × 104 macroconidia g−1 of sand. Each entry was evaluated twice in growth chambers, and percent survival was adjusted to the number of seedlings that germinated in the uninoculated trays. Mature bulbs produced in the field were screened by inoculating transversely cut basal plates with potato dextrose agar plugs containing spores of the same isolate at 3.0 × 104 macroconidia mL−1. FBR severity and incidence were then calculated after 20 days of incubation. Significant variation was found among the accessions for FBR-susceptibility (p < 0.001) at both the seedling and the mature bulb stages. Two sets of 18 accessions were identified either for their higher seedling survival or higher mature bulb FBR-resistance compared to the checks. Among them, PI 256326 (‘Baia Periforme’, the originator cultivar of ‘Serrana’) had a higher seedling survival than both the checks, and a lower mature bulb severity than the susceptible check. Another accession, PI 656956 (‘S015’), exhibited higher seedling survival than the susceptible check and a low FBR severity (4.3 on a 1 to 9 scale) and incidence (41.7%). These two accessions, which were known previously for their high intra-population heterogeneity and root or bulb resistance for FBR, respectively, show promise for incorporating FBR-resistance into short-day onion cultivars. The cultivar rankings could vary in future studies with a range of FOC isolates due to a high cultivar × isolate interaction as observed in past studies.

“…Responsável por quase a totalidade das mangas e uvas brasileiras de mesa exportadas, o Vale das Frutas, que já passou por diversos ciclos econômicos (GALVÃO, 2010), é reconhecido internacionalmente e faz do Brasil um importante player em termos de competitividade e eficiência na produção de frutas para exportação ( JESUS JUNIOR; SIDONIO;MORAES, 2011;QUEIROZ et al, 2012).…”

“…A denominação Vale das Frutas, portanto, merece ser adotada em razão dos seguintes entendimentos: a) a expressão "Polo Petrolina/Juazeiro" ou, simplesmente, "Juazeiro/ Petrolina" não mais efetivamente responde pela economia movimentada na região de seu entorno, pois muitas outras cidades circunscritas a Petrolina, no território pernambucano, e a Juazeiro, no território baiano, contribuem para que a região tenha sido evidenciada como um reconhecido caso de sucesso internacional (QUEIROZ et al, 2012); b) a expressão "Submédio do Vale do São Francisco" é ampla demais para representar a realidade da produção do agronegócio da região.…”

RESUMO:Poucos setores possuem uma representatividade econômica com tamanha importância como o agronegócio. A fruticultura, por sua vez, tornou-se um interessante objeto de estudo tendo em vista crescentes demandas nacionais e internacionais, não apenas a partir da perspectiva de produção, como também do consumo. O Vale das Frutas e, especificamente, o cultivo da manga, exercem, nesse contexto, um papel importante em razão do desempenho de produção agrícola alcançado. Este estudo é, portanto, motivado pela seguinte questão norteadora: como os acadêmicos estão estudando a mangicultura, no contexto do Vale das Frutas, na área de Engenharia de Produção? Nessa perspectiva, este estudo concentrou esforços metodológicos capazes de revelar o estado do conhecimento da área. Como fontes de pesquisas para esta discussão optou-se em estudar periódicos classificados no Qualis/Capes 2014 genuínos da área de Engenharia de Produção no estrato B5 ou superior, assim como os anais do ENEGEP. A análise dos resultados, a partir dos critérios adotados, revela que a produção científica brasileira sobre mangicultura no Vale das Frutas, na área de Engenharia de Produção, é bastante pontual e, em alguns casos, como em periódicos, surpreendentemente inexistente. PALAVRAS-CHAVE:Bibliometria; Estado do conhecimento; Fruticultura; Vale do São Francisco. MANGO-CULTURE AND THE FRUIT VALLEY: WHICH ARE THE SCIENTIFIC CONTRIBUTIONS OF PRODUCTION ENGINEERING?ABSTRACT: Agribusiness is perhaps one of the few segments with high relevant economic representativeness.

Drought in Northeast Brazil: A review of agricultural and policy adaptation options for food security

et al. 2021

View full text Add to dashboard Cite

The semiarid lands of Northeast Brazil represent one of the most densely populated regions of the country. Rainfall variability together with land degradation and large-scale poverty in rural areas makes this region vulnerable to droughts.Most of the agriculture in this region is rainfed and deficient rainfall leads to severe drought impacts. In this review, we examine different short-and long-term strategies directed to cope with possible impacts of droughts proposed by the government, farmers, civil society, and the private sector. These are approaches to adaptation to drought in the Northeast of Brazil, and among them, we have agricultural management and soil conservation and better management of water resources. Other actions include seasonal climate forecasts and funds transfer and credits to affected small-scale farmers. Although some of these actions are for the short term and may help to survive the drought situation, they may be only postdisaster mitigation options that do not improve adaptive capacity. They favor maladaptation and create dependency of farmers to government actions. Some experiences such as AdaptaSertão show potential benefits for small-scale farmers. We identify key challenges for moving toward a more holistic risk management approach and highlight the need to integrate actions and tools for adaptation, combining technology-based solutions with in-depth knowledge of local and regional social, economic, and cultural aspects, among them seasonal climate forecasts and drought impacts studies, among some other proactive predisaster ways, rather than reactive postdisaster actions. Adaptation strategies must increase long-term resilience of food production in the Brazilian Northeast, going beyond an individual drought event.
