摘要
有机施肥方案对农林复合系统(AFS)下可可生长和生产的影响研究甚少。在这个意义上,在Rivera (Huila-Colombia),评估了农林业系统下不同管理策略对可可改良剂应用的效果。考虑了四种处理:i)常规施肥或农民施肥(化学施肥,T1);ii)硫酸钾(化学,T2);iii) eco-cocoa + Super 4 (ECO-S4)(有机,T3);硫酸钾+生态可可(SP-ECO)(化学+有机,T4)混合处理。采用方差分析、Fisher检验(p<0.05)和主成分分析(PCA)进行数据比较。可可株高平均增加22.5 cm,茎粗平均增加4.71 cm,处理间差异显著。总的来说,施肥方案对可可的农艺参数有影响,特别是对一些重要的变量,如每荚粒数和籽粒平均重量。化学处理和有机处理之间有相似的参数。这表明有机施肥方案可能是提高可可产量的重要替代方案。
Contribución de esquemas de fertilización orgánica y convencional al crecimiento y producción de Theobroma cacao L. bajo arreglo agroforestal en Rivera (Huila, Colombia)
The impact of organic fertilizing schemes on the cocoa (Theobroma cacao L.) growth and production under agroforestry systems (AFS) has been scarcely studied.In this sense, in Rivera (Huila-Colombia), the effect of different management strategies for amendment application in cocoa under agroforestry systems was evaluated. Four treatments were considered: i) conventional fertilizing or farmer fertilizing (chemical, T1); ii) Potassium sulfate (chemical, T2); iii) eco-cocoa + Super 4 (ECO-S4) (organical,T3); and iv) the mixture of among the treatments with potassium sulfate + eco-cocoa (SP-ECO) (chemical +organical, T4). Variance analysis, Fisher test (p<0.05) and principal components analysis (PCA) were used fordata comparisons. For the height of cocoa plants, there was an average increase of 22.5 cm, while for stem diameter was 4.71 cm, with significant differences between the treatments. In general, an effect of the fertilizing scheme on the agronomic parameters of cocoa evaluated was found —especially for some important variables such as number of grains per pod and average weight of the grain—. There were similar parameters between the chemical and the organic treatments. This demonstrates that organic schemes of fertilizing could be an important alternative for improving cocoa production.
期刊介绍:
The journal Ciencia y Tecnología Agropecuaria (Science and Agricultural Technology) is a four-monthly scientific publication edited since October 1996 by the Corporación Colombiana de Investigación Agropecuaria - Agrosavia. The journal publishes articles on diverse thematic areas typical of the agricultural sector (multidisciplinary), written in Spanish or English, especially from Latin American and Caribbean researchers. The contributions that apply for the journal must be original and unpublished. The articles are reviewed by national and international peers (peer review). The journal is non-commercial and open access, this means that it doesn’t charge for the reception and/or publication of articles in both, its printed and digital version. The journal is aimed at the scientific community of the agricultural sector in Latin America and the Caribbean.
