Cacao Mineral Nutrition 2015

Picture1Executive summary
This literature review on mineral nutrition of cocoa was commissioned by the Scientific Committee of the Cocoa Fertiliser Initiative to address the following questions:
 What knowledge is currently available about mineral nutrition of cocoa?

 What are the current knowledge gaps?

 What are the key areas for further research?

Poor yields Current average cocoa yields in West Africa are around 400 kg/ha although yields of 5,000 kg/ha are achievable. Given the expected increase in global cocoa demand, and the diminishing incomes of cocoa farmers, there is an urgent need to increase cocoa yields.

Potential cocoa yields are determined by location and crop specific characteristics, such as climate and the crops natural life cycle, under otherwise optimal conditions. However, the availability of water and nutrients may limit production, and yields may be further reduced by weeds, pests and diseases. The gap between the potential yield and actual yield may be decreased by addressing the limiting and reducing factors with yield increasing and yield protecting measures.

As soil nutrient content in many cocoa growing regions is poor, an obvious way to increase yields is to address the nutritional needs of cocoa through fertiliser. However, the response of cocoa trees to fertiliser will remain limited unless the crop is well managed and in a healthy condition.

Potentially strong yield response to fertiliser, but differences in response poorly understood There is a strong cycling of nutrients within cocoa systems and the amounts of nutrients removed through harvest are relatively small. Yet in the long term cocoa production leads to depletion of soil nutrients. Although the soils upon which cocoa in West Africa was established used to be fertile, many of them are no longer able to provide the nutrients required to obtain good yields.

Several trials have shown that cocoa productivity can be more than doubled when fertilisers are applied. However, there is large variability in yields and fertiliser response, and in some cases fertilisers show little effect. The effects of fertilisers depend on the cocoa tree requirements and current nutrient availability from the soil, but also on other environmental conditions, presence of pests and diseases, and the management of shade trees and pruning of cocoa.

Most cocoa researchers agree that the largest cocoa yields can be obtained in systems with little shade and high rates of fertilisers under good management, but that yields show a sharp decline after 10 years of full production. Under shade, cocoa yields respond less strongly to fertiliser, but the yield decline is also less severe…
Narrow research base Various lines of research related to mineral nutrition of cocoa have contributed to current understanding, including the establishment of nutrient balances in different cocoa production systems, pot experiments, and short and long term fertiliser field trials on experimental plots or existing farms. Much of the primary research was conducted over 40 years ago. Many variables have not been adequately measured and quantified and only few treatments were compared. Research has been conducted under a restricted range of environments and regions and often for only a few years, whereas the life span of the crop can be 40 years or more. Conclusions drawn from these studies may only be valid under the circumstances under which the research has been conducted. Nevertheless, these conclusions continue to be reused and extrapolated to the present day, for instance for the establishment of (fertiliser) recommendations.

Terrace & Platform Construction: For Rolling Terrains

Terrace Construction Platform

Planting Cacao trees in a rolling terrain is a good idea. To prevent your investment from doing Adele’s “rolling in the deep“; here is a suggestion for that undulating hilly / slope area.

Do a terrace construction and/or planting-hole platform prior to your Cacao Planting. This way you could avoid run-off fertilizer, growing trees that fall to its side or cacao pods rolling downhill during harvest. Do that or you could have had it all.

Cacao Production And Environmental Issues In Central America


 Growing of cocoa plants does not come without an environmental cost.  There are issues that revolve around the growing of cacao in farms and the damage caused to the rainforests by these farms.

Brazil Shades Density Research

dana stuff

The effect of six planting densities on cacao yield of a commercial hybrid mixture as well as the interaction of planting densities with the years were investigated. Crop data collected over a 14-year period (1977-1990) showed that it was possible to optimise the regional cacao yields by implementing high planting densities (2500 and 1736 trees ha-1). This was however only true for the first half of the crop period. In the second half, low planting density (1059 trees ha-1) attained the best yields. This change in the ranking of planting densities over the years confirmed the presence of density-year interaction.
