| To estimate the cocoa dry bean weight from the fresh weight a standard dry bean factor (DBF) ranging from 32% to 40% is usually applied. This factor, i.e. the relation between the dry bean weight (fermented and dried) and the fresh weight at pod opening, is used by cooperatives and factories that buy the fresh beans of the farmers. However, this factor is subjected to seasonal fluctuations and can be highly influenced by rainfall. Therefore, for instance, higher values are expected during the dry season compared with the rainy season. The objective of this study was to evaluate the accuracy of the use of a standard fix DBF value compared with the use of actual DBF values periodically collected over the season for assessing the performance of 12 cocoa... |

| The Research Institute of Organic Agriculture (FiBL) established farming systems comparison trials in Bolivia, Kenya and India (SysCom). Besides long-term experiments, the program includes a participatory on-farm research (POR) component which aims at solving the most urgent problems of local farmers. In India, these related to nutrient management, organic pest control and seed availability, which were tackled using a combination of on-farm and on-station trials. We here present the methods, results and lessons learnt of the activities implemented in the POR component of SysCom in India. |

| The Technology Innovation Platform of IFOAM (TIPI) has developed a vision and strategy for organic farming research to advance organic agriculture through research, development, innovation and technology transfer. TIPI's vision and strategy was finalized in February 2016. TIPI’s vision recognizes that current technologies based on heavy use of external inputs that are toxic, pollute the environment and are very energy-intensive come at a price. Investments in ecosystem services and the development of technologies that are productive, stable, adaptable, resilient, and fairly shared are much more likely to sustain the world’s population in a rapidly changing environment. Sustainable pathways to innovation will require engagement of all stakeholders in a... |

| Shade trees in agroforestry systems protect the understory cocoa from climate extremes. Shade tree pruning manages microclimatic conditions in favor of cocoa production while tree diversity is maintained. Adaptation of pruning has to consider seasonal changes in temperature and precipitation to protect the understory cocoa. Context Structural characteristics of tree stands such as species diversity, tree density, and stratification can affect throughfall and microclimate. Pruning changes the canopy and may therefore modulate internal conditions. Aims The aim of this study is to assess the environmental growing conditions of cocoa trees. Methods We monitored canopy openness and the impact of stand structure on throughfall and microclimate in three... |

| Homemade organic pest control products offer an ecological, healthy and low-cost alternative to ready-made products. Yet the recipes are not standardised and the products vary in quality and concentration of the active ingredients. bioRe R, together with the Research Institute of Organic Agriculture (FiBL), engages in research activities to address this challenge and improve pest management strategies in organic farming. During the cotton cropping season 2013–14 one on-station and two on-farm trials were conducted with the objective of comparing different spraying intervals of the most commonly used home-made organic pest control products in order to identify an optimum level of crop protection. The study focused on the effect of the spraying intervals on... |

| The debate on the relative benefits of conventional and organic farming systems has in recent time gained significant interest. So far, global agricultural development has focused on increased productivity rather than on a holistic natural resource management for food security. Thus, developing more sustainable farming practices on a large scale is of utmost importance. However, information concerning the performance of farming systems under organic and conventional management in tropical and subtropical regions is scarce. This study presents agronomic and economic data from the conversion phase (2007–2010) of a farming systems comparison trial on a Vertisol soil in Madhya Pradesh, central India. A cotton-soybean-wheat crop rotation under biodynamic,... |

| High soil pH levels may limit the availability of phosphorous (P) to crops. In organic farming, the use of synthetic P fertilizers is not allowed. Application of rock phosphate (RP) to crops is one of the alternatives for organic production. However, RP application shows little effect on high pH soils, because the P is not transformed into plant-available forms under alkaline soil conditions. Aiming at the development of locally adapted solutions, we followed a Participatory Technology Development approach, making use of the local knowledge to identify current practices and associated problems by conducting focus group discussions with organic farmers. Farmers stated that they are facing challenges with a P limitation in their cotton-based production... |

| The cocoa mirid (Monalonion dissimulatum) is one of the major pests in cocoa cultivation in Alto Beni, Bolivia, causing up to 50% yield losses. The most common control method is the manual removal of the nymphs sucking at the pods in the morning. This practice is very time-consuming, and farmers often do not dispose of enough time to perform these control measures. Therefore, there is an urgent need for more efficient practices to control this important pest. The present study evaluated the pathogenicity of two strains of Beauveria bassiana for the control of Monalonion dissimulatum on cocoa: a non-native, commercialized strain (Probiobass MR, Probiotec S.R.L.), and a native strain of Alto Beni, which is not yet commercialized (isolated by the local... |

| The cocoa swollen shoot virus disease is a major factor limiting cocoa (Theobroma cacao L.) productivity for West African farmers. The only treatment against this disease is to cut infected trees and replant with disease-free planting material. Research has recommended the prevention measures: (i) cordon sanitaire (leaving 10-m-wide cocoa-free zone around cocoa), (ii) barrier cropping, (iii) using partly tolerant hybrids, and (iv) removing specific alternative host tree species. Here, we evaluate the current adoption of these measures and identify their adoption constraints. We conducted a quantitative survey with 396 farmers in the Eastern and Western Regions of Ghana, held six focus group discussions and hosted a multi-stakeholder validation workshop... |

| The global demand for cacao has recently increased. To meet this demand, the cultivated area has been expanded in tropical forest areas and production has intensified by replacing traditional agroforestry systems with monocultures. This has led to a loss of biodiversity in cacao-growing areas. More sustainable production systems such as agroforestry and organic managed systems are expected to yield less cacao, but by-crops and premium prices, respectively, might economically compensate for the lower yields. Here, we compared the productivity and the return on labor, that is the return per working day, of four different cacao production systems: agroforestry and monocultures under organic and conventional management. Cacao and by-crop yields, costs,... |

| This study compares aboveground and belowground carbon stocks and tree diversity in different cocoa cultivation systems in Bolivia: monoculture, simple agroforestry, and successional agroforestry, as well as fallow as a control. Since diversified, agroforestry-based cultivation systems are often considered important for sustainable development, we also evaluated the links between carbon stocks and tree diversity, as well as the role of organic certification in transitioning from monoculture to agroforestry. Biomass, tree diversity, and soil physiochemical parameters were sampled in 15 plots measuring 48 × 48 m. Semi-structured interviews with 52 cocoa farmers were used to evaluate the role of organic certification and farmers’ organizations (e.g., cocoa... |

| Yams (Dioscorea spp.) are tropical tuber crops with high food and market values, contributing significantly to food security in West Africa. The traditional method of cultivation is without fertilizers as the first crop after clearing land from natural vegetation (e.g. forests) because of their high requirements in terms of soil fertility. However, due to increased population pressure on arable land, forests have become rare, fallow periods shorter, and long term fallowing more difficult in West Africa. Consequently, declining soil fertility is one of the major constraints to yam productivity and yam yields are thus far below the estimated potential. These problems call for the development of more integrated and sustainable yam production systems. |

| Organic food and farming systems have a great untapped potential to provide the world with healthy, high-quality food that is produced and distributed in an ecologically sound and fair way, but numerous production challenges and barriers slow the adoption of organic practices. Innovations addressing these challenges are not being developed sufficiently because of insufficient capacity in research, development and technologytransfer, especiallyinAfrica, Asia and Latin America. Given the limited resources, as well as the specific needs of organic food and farming systems, different pathways are needed to develop new technologies that are compatible with the principles of organic farming. The Technology Innovation Platform of IFOAM... |

| One of the most essential limiting factors of cocoa (Theobroma cacao L.) productivity worldwide is pests and diseases. Each of the major production regions has its specific pests and diseases. Reported yield losses range from minor to almost 100 per cent. In Alto Beni, located in the Amazonian watershed of the department La Paz, Bolivia, the Research Institute of Organic Agriculture (FiBL) and its local partners are addressing several problems of cocoa producers using a participatory technology development approach. Problems were identified in a participatory way and are, in order of priority, i) to reduce the incidence of pests and diseases, mainly the cocoa mirid (Monalonion dissimulatum) and Frosty Pod Rot (Moniliophthora roreri); ii) to evaluate the... |

| Cocoa cropping systems vary from full-sun monocrops to highly diversified agroforestry systems, which combine the cocoa production with by-crop such as bananas or plantains and trees with different functions. Additionally, these systems can be organically or conventionally managed. Although labour demand is one of the main activities contributing to the total production costs of the plantations and it may highly differ between production systems, there are still scarce data and information available. In this study we present the labour demands of five different production systems in a newly established cocoa plantation in Alto Beni, Bolivia. The trial was established in 2008 within the framework of the SysCom programme (www.systems-comparison.fibl.org)... |
