Produtividade do cacaueiro em função de características do solo: II. características físico-morfológicas e alguns elementos extraídos pelo ataque sulfúrico

Abstract: RESUMOCom base na produtividade em sete anos (1989 a 1995) de 36 talhões produtivos de cacau, cultivados numa propriedade agrícola no sul da Bahia, foram obtidas as médias dos três anos mais e menos produtivos, correspondendo, respectivamente, a anos de maior e menor quantidade de chuvas. Essas produtividades foram relacionadas, por análise de trilha, com as características físico-morfológicas do solo (profundidade do horizonte A; cor, porosidade, densidades aparente e de partícula dos horizontes A e B; textur… Show more

“…Souza Júnior et al (1999) comment that the highest yields are expected in the season, but it is possible to claim, based on the results of the present study, that with high levels of soil fertility the yield of off-season cocoa can be equally high or higher.…”

“…Souza Júnior et al (1999) comment that a good cocoa yield results from the balance between the nutrients of the soil. According to these authors, soils that are rich in micronutrients tend to be more productive, provided that these elements do not reach toxic levels.…”

“…Estas relações poderiam ser descritas matematicamente pela análise multivariada, utilizando-se o método de análise de trilha descrito por Cruz et al (2004). A aplicação da análise de trilha em cacaueiro revelou que as características físicas do solo explicaram melhor a produtividade dos anos mais secos do que os mais chuvosos e não foi comprovada que a presença de cascalho até à profundidade de 50 cm comprometia a produtividade de cacau (Souza Jr. et al, 1999).…”

“…Cacao cultivated region in southeastern Bahia has wide soil variability, containing 30 units or 19 large pedological groups, classified by the American Soil Classification System (Soil Taxonomy), which are equivalent to 13 soil classes according to the Brazilian Soil Classification System (Santana et al., 2002). Therefore, these soils have a great geological diversity as well as mineralogical, chemical, and physical attributes (Souza Júnior, Ker, et al., 1999; Souza Júnior, Mello, et al., 1999; Chepote et al., 2012; Arévalo‐Hernández et al., 2019). Among the soil attributes, the physical ones are very important for crop development and productivity especially in less rainy years, as they greatly influence soil water dynamics including infiltration rate and available water‐holding capacity.…”
