Potencial pedoclimático do Estado da Bahia para o cultivo da atemóia

Abstract

RESUMOA cultura da atemóia tem despontado como opção de exploração comercial no Estado da Bahia, mas a expansão de áreas produtoras está sendo realizada sem prévio conhecimento das suas exigências climáticas e pedológicas. Em decorrência disso, o objetivo deste trabalho foi realizar um zoneamento pedoclimático para o cultivo da atemóia no Estado da Bahia, com base em indicadores de clima e solo estabelecidos de acordo com as exigências da cultura. Constatou-se, a partir do cruzamento das informações entre os mapas temáticos climático e pedológico, que 19,3% do território baiano apresentam condições adequadas para o cultivo da atemóia. Áreas marginais e inaptas também foram identificadas cobrindo, respectivamente, 13,9 e 24,3% do estado. Verificou-se também que 42,5% das áreas do estado possuem restrições à exploração comercial desta espécie devido, principalmente, às limitações climáticas; entretanto, as áreas que apresentam apenas restrições quanto à deficiência hídrica do solo devem ter o cultivo incentivado pelo uso da irrigação uma vez que as condições ideais dos fatores pedológicos e demais fatores climáticos podem favorecer a obtenção de bons rendimentos.

However, the expansion of the cultivated area is being conducted without knowledge of the climatic and pedologic crop requirements. The objective of this work was to carry out a pedoclimatic zoning for atemoya cultivation in the State of Bahia based on established criteria of climate and soil according to crop requirements. By crossing the information between climatic and pedologic thematic maps, it was verified that 19.3% of the state territory exhibited appropriate conditions for crop production. Marginal and unsuitable areas were also identified, covering 13.9 and 24.3% respectively of the state area. Restrictions for atemoya cultivation were also observed in the major part of the territory (42.5%), which is caused mainly by climatic limitations. However, areas that present soil water deficiency only should have the cultivation encouraged by the use of irrigation since ideal conditions of the pedologic and the remaining climatic factors may be appropriate for obtaining high income.

“…These models have been adjusted for various tropical forage species, such as Cynodon, Panicum and Urochloa brizantha (CRUZ et al, 2011;PEZZOPANE et al, 2012aPEZZOPANE et al, , 2012bTONATO et al, 2010). Furthermore, the use and improvement of geographic information systems (GIS) have increased the application of geoprocessing techniques, which allow a rapid delimitation of potential productive areas for crops, with reliable results (SILVA et al, 2009). GIS are used to collect, analyze, organize and layer spatial data describing the physical and logical properties of the geographic world (BURROUGH; MCDONNELL, 1998).…”

CALIBRATION OF THE THERMAL DISSIPATION PROBE FOR ATEMOYA: (Annona squamosa x A. cherimola)

“…The hybrid atemoya (Anonna squamosa x Anonna cherimola) obtained from the crossing of sweetsop with cherimoya, is among the few commercial species of the Annonaceae family that has received special attention from Brazilian producers and consumers (Silva et al, 2009). This tropical fruit is one of the alternatives with high potential; it is appreciated by the internal and external markets for its pleasant taste as well as its nutritional and medicinal properties (Martin & Souza Neto, 2015).…”

“…However, in the Northeast region, the expansion of its cultivation is still limited, primarily because of the lack of technical-scientific knowledge for its cultivation. Therefore, more studies on the management of this plant are required (Silva et al, 2009), which will provide reliable information that can assist producers in the production process, especially in relation to water use. This plant requires water in great abundance for its growth and functioning (Taiz et al, 2017).…”

Zoneamento agroclimático da palma forrageira (Opuntia sp.) para o estado da Paraíba

“…O zoneamento de aptidão climática é uma ferramenta de extrema importância e amplamente utilizada no planejamento do calendário agrícola, na definição das linhas de financiamento rural e na avaliação de impactos climáticos sobre o rendimento das culturas. Por essas razões, o zoneamento agroclimático de várias culturas tais como café, cana-de-açúcar, algodão e laranja, dentre outras, tem sido feito para diferentes regiões brasileiras (Assad et al, 2013;Nunes et al, 2007;Silva et al, 2009;Medeiros et al, 2009;Possas et al, 2012).…”
