The objective of this work was to assess the incidence of Yellow Sigatoka in banana plants cultivated with deficiencies of nitrogen, phosphorus, potassium, calcium, magnesium, sulfur or boron. The experimental design was a randomized complete block with 8 treatments, 4 repetitions and 1 plant per repetition. The treatments were supplied in solution culture and consisted of all the nutrients (control) or nitrogen (N), phosphorus (P), potassium (K), calcium (Ca), magnesium (Mg), sulphur (S) or boron (B) deficiency. Leaves 1 and 2 were inoculated on the abaxial surface with a suspension of conidia and assessed every 5 days to with a total of 5 assessments. The average number of lesions were integrated for the area under the disease progress curve (AUDPC). The greatest AUDPC occurred in plants deficient in K, N, P, S, or Mg. Plants deficient in N, P, K, Ca, Mg, S or B had lower leaf contents of these nutrients and showed morphological changes expressed in visual deficiency symptoms. Thus, banana plants deficient in K, N, P, S or Mg had a greater incidence of Yellow Sigatoka, compared with plants with full nutrients and plants deficient Ca or B.

In spite of various initiatives, Caribbean countries continue to have difficulties in addressing demands of monitoring and measuring progress towards the fulfilment of the Millennium Development Goals (MDGs) and other Internationally Agreed upon Development Goals (IADGs)1. To address this gap, the Economic Commission for Latin America and the Caribbean (ECLAC) has received funding for a technical assistance project, Strengthening the capacity of National Statistical Offices (NSOs) in the Caribbean Small Island Developing States to fulfil the Millennium Development Goals and other Internationally Agreed Development Goals (IADGs). The main imperative of the project is to support the strengthening of national institutional capabilities for generating reliable data to meet these monitoring and reporting requirements. The project seeks to build on past and current initiatives directed towards broadening and improving statistics and indicators through the use of already available knowledge, experience and expertise at the national and regional level. In an effort to avoid duplication of present or repetition of past activities in this field, ECLAC considered it important to conduct a thorough assessment of the status and structure of MDG and IADG monitoring and reporting at the national and regional levels as well as to provide an overview of initiatives undertaken by other regional development partners and intergovernmental bodies in the subregion. This paper is composed as follows: The first chapter of the document will present an overview of the statistical infrastructure at the national level, followed by a summary of the results of a survey administered to Caribbean NSOs that gathered information on the status of and mechanisms in place in MDG and IADG monitoring and reporting at the national level. Then, an attempt will be made to provide a briefing on activities carried out by intergovernmental bodies and development partners in the region. The fourth section presents a brief summary of data sources for secondary data and introduces concepts for metadata collection and reporting. It further discusses major challenges with poverty measurements and monitoring in the subregion. The paper ends with a summary and recommendations for the way forward.
