“…Eastern and Southern Africa, where banana production is limited by low temperature, are projected to experience increases in suitable area ranging from 1% to 11% by 2020 (Ramirez et al. ). However, variability in rainfall is expected to result in a loss of suitable areas in the lowlands (Ramirez et al.…”

“…However, variability in rainfall is expected to result in a loss of suitable areas in the lowlands (Ramirez et al. ). Though higher temperatures may increase suitable areas, rises in temperature also result in increased water demand, limiting banana cultivation to the areas projected to receive increased rainfall (Thornton ).…”

Global warming has become one of the major challenges in maintaining global food security. This paper reviews the impacts of climate change on fourteen strategic crops for eight sub-Saharan Africa countries. Climate change is projected to increase median temperature by 1.4-5.5°C and median precipitation by −2% to 20% by the end of the 21st century. However, large levels of uncertainty exist with temporal and spatial variability of rainfall events. The impact of climate change on crop yields in the region is largely negative. Among the grain crops, wheat is reported as the most vulnerable crop, for which up to 72% of the current yield is projected to decline. For other grain crops, such as maize, rice and soybean, up to 45% yield reductions are expected by the end of this century. Two grain crops, millet and sorghum, are more resilient to climate change for which projected impacts on crop yields are <20%. Root crops, such as sweet potato, potato and cassava are projected to be less affected than the grain crops with changes to crop yields ranging from about −15% to 10%. For the two major export crops, tea and coffee, up to 40% yield loss is expected due to the reduction in suitable areas caused by temperature increase. Similar loss of suitable areas is also expected for banana and sugarcane production, however, this reduction is due to rainfall variability in lowland areas. Other crops such as cotton and sugarcane are projected to be more susceptible to precipitation variation that will vary signifi cantly in the region. In order to mitigate the long-term impacts of climate change on agricultural sectors, the development of small-scale irrigation systems and water harvesting structures seems promising, however, affordability of such measures remains a key issue. 111

“…However, in Period 2, mean maximum and minimum daily temperatures, precipitation and radiation were recorded at 4.56 and 4.04°C, 186.42 mm and 5.42 MJ m -2 , respectively (Table 1). Temperatures <14°C and >30°C, unsuitable for banana growth (RAMIREZ, 2011), occurred in the two periods; however, with a marked difference in their frequency (Table 1). The lowest temperatures occurred between early evening and early morning, while the highest temperatures occurred at higher radiation times, a more frequent condition in Period 2.…”

Effect of Defoliation on the Yield and Quality of ‘Prata Comum’ Banana Fruits

et al. 2017

-With the advent of black sigatoka in commercial banana crops in the "Vale do Ribeira" region, state of São Paulo, the monitoring the severity and chemical control of the disease in susceptible varieties have become more frequent in order to avoid leaf loss. This study simulated the effect of defoliation caused by the disease on the yield and quality of 'Prata Comum' banana fruits, depending on the formation period and fruit position in the bunch. The experimental design was completely randomized in a 2 x11 factorial scheme (period of bunch formation x number of leaves at flowering), 6-16 leaves at flowering in two periods of bunch formation with six replicates. In Period 1, flowering occurred at 04/15/13 and in Period 2 at 01/07/14, although in Period 1, bunch mass was higher and in Period 2, higher average maximum and minimum daily temperatures, precipitation and radiation were observed. Regardless of formation period, the number of leaves at flowering affected bunch mass, which ranged from 18 to 23 kg plant -1 . Defoliation affected the size of fruits of hand 1 and last hand of the bunch, but not the variability in fruit size due to the position the fruit occupies in the bunch and physicochemical characteristics. Index terms: Musa sp., Sigatoka negra, bunch mass, fruit size, source/sink ratio. EFEITO DA DESFOLHA NA PRODUÇÃO E NA QUALIDADE DOS FRUTOS DA BANANEIRA-'PRATA COMUM'RESUMO -Com o advento da Sigatoka-negra nos bananais comerciais do Vale do Ribeira-SP, o monitoramento da severidade e o controle químico da doença em variedades suscetíveis passaram a ser mais frequentes, a fim de evitar a perda de folhas. Dessa forma, foi realizada a simulação da desfolha causada pela doença, com o objetivo de avaliar seu efeito na produção e na qualidade dos frutos da bananeira-'Prata Comum' (AAB), em função do período de formação e da posição da penca no cacho. O delineamento experimental foi o inteiramente casualizado, em esquema fatorial 2x11 (dois períodos de formação do cacho x número de folhas na floração (6 a 16), com seis repetições. No Período 1, a floração ocorreu em 15-04-13 e no Período 2, em 07-01-14. Apesar de, no Período 1, a massa do cacho ter sido mais elevada, no Período 2 observou-se temperaturas médias diárias máximas e mínimas, precipitação e radiação mais elevadas. Independentemente do período de formação, o número de folhas na floração afetou a massa do cacho, que variou de 18 a 23 kg planta -1 . A desfolha afetou o tamanho dos frutos da penca 1 e a última penca do cacho, mas não a variação de tamanho dos frutos em função da posição eles mesmo ocupam no cacho e as características físico-químicas. Termos para indexação: Musa spp., Sigatoka negra, massa do cacho, tamanho do fruto, relação fonte/dreno. 1 (Paper 259-15).

“…Curah hujan yang berlebihan sangat mempengaruhi tingkat produktivitas pisang (Opeyemi et al, 2016). Tanaman pisang sangat rentan terhadap kondisi tanah yang jenuh air atau tergenang, sehingga harus dicegah dengan pengelolaan drainase yang baik (Ramirez et al, 2011). Kebutuhan air yang optimum untuk tanaman pisang berkisar antara 1.300 -2.600 mm/tahun, kadar air dalam tanah yang mencukupi atau pengelolaan irigasi yang baik dapat memberikan efek yang menguntungkan pada tanaman pisang seperti percepatan pematangan buah, meningkatkan hasil panen, bobot buah yang lebih besar, dan peningkatan jumlah buah per tandan (Stover, 1972;Sastry, 1988).…”
