“…Previous studies have also reported low levels of available P in West African cocoa farms [26,27,28,29,30]. This can be attributed to soil acidity, causing interference with the availability and uptake of certain nutrients, such as P [27], and the relatively low use of mineral fertilizers [30]. Our results of the farmers interviewed further confirms communications from earlier studies that have consistently shown that most Nigerian cocoa farmers do not use chemical fertilizers [31,4,32,33], hence inadequate nutrients in the soil.…”

Nutrients are being removed through pod harvest without replacement in the form of fertilizer application leaving the soil impoverished and the nutrients grossly inadequate for optimum cocoa yield. To address this issue, a randomised complete block designed study was carried out to examine the effects of readily available source of organic fertilizer like cocoa pod husks compost combined with mineral fertilizers on the yield of cocoa. The treatments with three replications consisted of Compost (100%), Compost (75%) + NPK (25%), Compost (50%) + NPK (50%), NPK (100%) and Control (no fertilizer). Results indicated that cocoa yield obtained with the compost plus NPK fertilization was significantly higher than with sole compost, NPK applications, and control in all locations. Percentage dry cocoa bean yield gain was 72.4% with the compost plus NPK fertilization, while sole compost or NPK alone was 36.4% compared to the control. Additionally, compost plus NPK fertilization significantly reduced black pod losses compared to sole compost, NPK, or control with percentage loss rate ranging from 9.9 to 13.4%, 21.6 to 23.1, 19.6 to 22.3, 32.2 to 35.5, respectively, in all locations. The use of CPH-based compost plus NPK fertilization has the potential to provide efficient integrated soil fertility restoration scheme that incorporated good agricultural practices and addressed disease management.

“…We also recognize that this measure is only a rough estimate of fertilizer volumes and, therefore, does not allow us a mechanistic understanding of its influence on yields. At the time of writing, research is ongoing as to the optimal fertilizer management for cocoa cultivation, particularly with respect to addressing declining soil fertility in smallholder systems (Koko, 2014). More broadly, there is a dearth of data collected from smallholder systems, which is increasingly being recognized by development donors (Tollefson, 2018), with the majority of agronomic best practice based on recommendations from highly-controlled trials performed ex situ by research institutes.…”

Cocoa yields in Ghana remain low. This has variously been attributed to low rates of fertilizer application, pollinator limitation, and particularly dry growing conditions. In this paper we use an African forest-agriculture landscape dominated by cocoa (Theobroma cacao) to develop an ecological production function, allowing us to identify key ecological and management limits acting on cocoa yields simultaneously. These included more consistent application of fertilizers inter-annually, distributing rotting biomass throughout the farm and reducing the incidence of capsid attacks. By relaxing these limits, we estimate plausible increases in yields and, by extension, farm incomes. Our analysis reveals that resulting increases in cocoa yields requiring both ecological and intensive management interventions could be significant (113 ± 60%); however, benefits are disproportionately realized by the wealthiest households. We found that wealthier households benefited proportionally more from ecological intensification methods (e.g., leaving more rotting biomass in their farms) and the poorest households benefited proportionally more from capital-intensive intensification methods (e.g., pesticide and fertilizer applications). We treated poverty as multi-dimensional, and show that only certain dimensions of poverty (school attendance, assets, and food security) are significantly related to cocoa incomes, while several other dimensions (access to clean water, sanitation and electricity, and infant mortality) are not. We explore how increased household cocoa incomes could impact different dimensions of poverty. Our findings suggest, that if all households adopted the optimal level of each of these management options, and in so doing had similar poverty profiles to those households already managing optimally, we would see the community-averaged probability: a child of a household misses school decrease from 47 to 31%, a household would be able to acquire assets increase from 40 to 59% and a household would have access to an adequate amount of food increase from 62 to 79%.

“…Nursery production necessarily requires mineral fertilization of the NPK nature [19]. However, the use of mineral fertilizers in cocoa trees has the major consequences of acidification and imbalance in the soil under fertilized cocoa [2,11,20,43]. The production of cocoa plants in the nursery depends mainly on the availability of nutrients in the soil contained in each pot [1].…”

Cocoa farmers face many problems related to the acquisition of quality planting material for their farms to guarantee a good annual yield of cocoa beans. This is justified by the multiple constraints to which the cocoa tree is subjected to from the nursery. Faced with this, research is based on the diversification of production systems to reverse this trend. One of the promising methods is the promotion of the use of mycelial microorganisms such as Mycorrhizae to obtain vigorous plants resistant to various pathogens in the nursery. To achieve these objectives, the microbiological characterization of the different substrates used by nurserymen and the impact of fertilizers on the development parameters of young cocoa plants of the Tafo 79/501 variety were evaluated in the nursery. The results obtained indicate that the substrates used by nurserymen contain the AMF spores. However, the germination of these spores and the survival of mycorrhizal structures are compromised by the regular use of pesticides. Also, the height of the stem, the diameter at the collar of the stem, the fresh and dry biomass, the chlorophyll rate as well as the rate of root colonization of AMF are higher in cocoa plants whose substrate has been inoculated with AMF compared to other pots. Overall, biofertilizers are conducive to the harmonious development of cocoa seedlings in the nursery, which guarantees good productivity.
