| Organic agriculture is one of the most widely known alternative production systems advocated for its benefits to soil, environment, health and economic well-being of farming communities. Rapid increase in the market demand for organic products presents a remarkable opportunity for expansion of organic agriculture. A thorough understanding of the context specific motivations of farmers for adoption of organic farming systems is important so that appropriate policy measures are put in place. With an aim of understanding the social and biophysical motivations of organic and conventional cotton farmers for following their respective farming practices, a detailed farm survey was conducted in Nimar valley of Madhya Pradesh state in central India. The study area... |

| 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... |

| Unlike the top-down approach of conventional research, participatory research methods offer a bottomup approach, involving all major stakeholders from the beginning of a research project. Integration of the end users of research (i.e. farmers) enhances the acceptance and adoption of innovations, along with making the best use of the local knowledge that is available. The Research Institute of Organic Agriculture (FiBL), Switzerland – one of the world’s leading institutions in the field of organic agricultural research – participates in numerous international projects, involving research, consultancy, training and development cooperation. With the objective of providing sound scientific information by comparative analysis of various agricultural management... |

| Hintergrund und Bedeutung für Coop Indien ist seit jeher Zeiten ein wichtiger Exporteur von Baumwolle. Im Jahr 2014 / 15 war Indien der größte Baumwollproduzent weltweit, mit 6,5 Millionen Tonnen produzierter Baumwollfaser. Indien ist auch der größte Produzent von "Bio-Baumwolle", mit einem Anteil von fast drei Viertel (74 %) der globalen Bio-Baumwolle Produktion. Weil die Nachfrage nach Biobaumwolle stetig wächst, ist es wichtig, die Produktion von Bio-Baumwolle auf nachhaltige Weise zu sichern – um so mehr, da sich der Anbau von genetisch modifizierter Baumwolle rasch ausbreitet. Dies ist auch für Coop äusserst zentral angesichts dessen, dass Indien der Hauptlieferant ist von Biobaumwolle für die Naturaline-Eigenmarke. Tatsache ist, dass sich in Indien... |

| Background: The important greenhouse gas (GHG) methane is produced naturally in anaerobic wetland soils. By affecting the production, oxidation and transport of methane to the atmosphere, plants have a major influence upon the quantities emitted by wetlands. Different species and functional plant groups have been shown to affect these processes differently, but our knowledge about how these effects are influenced by abiotic factors such as water regime and temperature remains limited. Here we present a mesocosm experiment comparing eight plant species for their effects on internal transport and overall emissions of methane under contrasting hydrological conditions. To quantify how much methane was transported internally through plants (the chimney... |

| Zinc (Zn) nutrition is of key relevance in India, as a large fraction of the population suffers from Zn malnutrition and many soils contain little plant available Zn. In this study we compared organic and conventional wheat cropping systems with respect to DTPA (diethylene triamine pentaacetic acid)-extractable Zn as a proxy for plant available Zn, yield, and grain Zn concentration. We analyzed soil and wheat grain samples from 30 organic and 30 conventional farms in Madhya Pradesh (central India), and conducted farmer interviews to elucidate sociological and management variables. Total and DTPA-extractable soil Zn concentrations and grain yield (3400 kg ha-1) did not differ between the two farming systems, but with 32 and 28 mg kg-1 respectively, grain Zn... |

| 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. |

| In 2007 two long-term trials were established in Kenya to contribute research-based evidence to the global debate on the productivity, economic viability and sustainability of different agricultural production systems. These trials compare conventional (Conv) and organic (Org) farming systems at high and low input levels at two locations, i.e. Chuka, with Humic Nitisols, high inherent soil fertility and rainfall, and Thika, with Rhodic Nitisols with low soil fertility and rainfall. The high input systems (High) represent commercial-scale, export-oriented production that uses the recommended amounts of fertilisers, pesticides and irrigation water to generate high yields, whilst the low input systems (Low) represent local smallholder practices, using... |

| In recent years, the limitations of top-down approaches for development-oriented research have become apparent. Therefore, scientists have started to explore alternatives such as participatory research. By involving many stakeholders throughout the different stages of innovation development, participatory research helps tackling the multi-faceted challenges the global food system is facing today. Since almost a decade, the Research Institute of Organic Agriculture (FiBL) has been running a large program called “Farming Systems Comparison in the Tropics” (SysCom) in Bolivia, India and Kenya. Besides maintaining four Long-Term farming systems comparison Experiments (LTE), Participatory On-farm Research (POR) is a strong component of SysCom. In POR, we aim... |

| Mobilization of unavailable phosphorus (P) to plant available P is a prerequisite to sustain crop productivity. Although most of the agricultural soils have sufficient amounts of phosphorus, low availability of native soil P remains a key limiting factor to increasing crop productivity. Solubilization and mineralization of applied and native P to plant available form is mediated through a number of biological and biochemical processes that are strongly influenced by soil carbon/organic matter, besides other biotic and abiotic factors. Soils rich in organic matter are expected to have higher P availability potentially due to higher biological activity. In conventional agricultural systems mineral fertilizers are used to supply P for plant growth, whereas... |

| Rapid population growth, increasingly complex economies and novel industrial uses of agricultural products call for further intensification of agriculture, particularly in the tropics. How to achieve sustainable intensification of food production systems in tropical regions that are challenged by ongoing climate change, loss of natural resources and biodiversity is a matter of debate. Here we highlight the major knowledge gaps in agricultural research and policy that must be addressed to develop adequate governance and regulatory frameworks for sustainable agricultural intensification. They include quantification of the (i) value of (public/private) goods generated by ecosystem services, (ii) costs to conserve the natural resources and biodiversity that... |

| Aims and Methods Vascular plants are known to influence the production, transport and oxidation of methane in wetland soils, but these processes are not well understood. Using plants grown in intact peat cores, we compared the influence upon methane emissions of 20 forb and graminoid species from European wetlands. We measured plant-mediated transport of methane (conduit or chimney effect) using a novel agar-sealing technique that prevented methane exchange from the bare soil to the atmosphere. Important Findings The plant-mediated transport (chimney effect) represented between 30% and almost 100% of the total methane flux, with graminoids exhibiting greater internal transport than forbs. In general, plants with less dense root tissues and a relatively... |

| India is the largest producer of ‘organic cotton’, as it contributes about three quarters (74%) to the global organic cotton production. The Nimar valley of Madhya Pradesh in central India is important region for organic cotton production. In general, cotton yields are low and variable in the Nimar valley and often do not reach the attainable levels on several farms of the region. With a steeply increasing demand for organic fibre, it is important to safeguard and increase the production of organic cotton in a sustainable manner. The precise understanding of social and biophysical motivations of different farmers for following their respective farming practices is of high importance for sustainable future of organic cotton in central India. The study of... |
