Study recommends improved cocoa systems for increased nutrition

By Seniorl Anzu

More cocoa research is needed to improve the understanding of nutrition related limitations to cocoa production in PNG, according to a technical report published recently by the Australian Centre for International Agricultural Research (ACIAR). This was one of the four main recommendations in this latest ACIAR publication on PNG cocoa entitled “Nutritional status of cocoa in Papua New Guinea”.

Report cover

The other recommendations were for the PNG cocoa industry to produce appropriate nutrient management practices for the different regions of the country; establish  effective pathways to adoption; and engage in education and capacity building initiatives for continued improvements in nutrient management research and extension.

The documentation follows a study led by the PNG Cocoa Coconut Institute (CCI) with Australian partners in 63 locations covering nine provinces countrywide recently.

Supported by ACIAR, the study was aimed at determining the nutrient status of cocoa in PNG, and to recommend further steps to determine if there are nutrient-related constraints on productivity, and how they might be overcome.

Information was gathered through cocoa block holder surveys in the 63 locations and plant and soil sample analysis from these sites, stakeholder workshops and research
trials at the Tavilo Research Centre, East New Britain.

The report indicated that there were no external market constraints to low productivity of PNG cocoa but common factors were lack of appropriate agronomic knowledge, land shortages, low level of block maintenance, labour shortages, and theft.

And the devastating cocoa pod borer pest had drastically reduced cocoa yields in the country with annual production in East New Britain alone, the most important cocoa-producing region, “fell by over 60% to approximately 8,000t” in 2009. “PNG cocoa is known for its good and consistent quality, with particular flavour, high fat content and large beans”, said the report.

Quality and demand for PNG cocoa were good, partly due to good germplasm and quality
control but productivity was the main limitation to increased income from cocoa. It said: “For the cocoa industry to recover and prosper, it is essential that management of smallholder cocoa blocks improves dramatically.” This includes widespread replanting and demonstrations using the integrated pest and  disease management package.

The plant tissue samples were analysed at the Waite Analytical Services in Adelaide
and soil sample analysis done in Townsville by Australia’s Commonwealth Scientific and Industrial Research Organisation (CSIRO). The leaf sample analysis demonstrated widespread nutrient deficiency in nitrogen (N) and iron (Fe) – “with 95% of sampled blocks falling below the critical level for N and 89% for Fe. Phosphorus deficiencies were encountered in about a ¼ of the blocks sampled”.

ACIAR has been involved in partnership with PNG research and development
organisations in carrying out some of the necessary research in an array of agriculture, forestry and fisheries issues and this was one of them.

The report also noted the eminent need for capacity building within CCI and the
National Agricultural Research Institute in the areas of, among others, field trials, data processing, sampling, methods of analysis, training and exposure.

    PNG still lack the capacity of statistical analysis in Natioanla Agriculture Research systems. Few Nationals that we had have passed on either retired or moved onto other areas. Universities where mathematics are taught mainly statistical courses seem to be only place that should be utilised or partner with to provide indutry support. Is this occuring? I read the above news with concern especially when the report said PNG’s capacity is limited in data processing and analysis. Open to discussion.

    Exactly, that point has been raised at various stages within the PNG NARS for some time. Hope someone or NARS member is taking it seriously. During the time of the ACNARS project (AusAID), a specific training input was made which benefited both the private and public sectors. Did PNG take anthing on from there? Biometrics and statistical analysis are crucial for research planning, execution and presentation/anlysis and if PNG does not have that capacity than we have a missing link with respect to our research efforts. Has the recent NARS policy workshop that into account?
