| 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... |

| Introduction and methods Crop mixtures of cereals and legumes have received recent attention in the scope of climate change and local protein supply. Cereal-legume mixtures are known to increase yield and yield stability compared with pure crops. Thus dedicated breeding strategies for mixed cropping might become necessary. As a model crop, we compared 32 current European spring pea (Pisum sativum L.) and 8 current spring barley (Hordeum vulgare L.) cultivars for their yield performance in mixed and pure stands, with pea as the focal species. Trials were done as an incomplete factorial design (Fig. 1) at two locations in Switzerland with two replications (Fig. 2). We calculated variance components for the general and specific mixing ability (GMA and... |

| In this paper, we describe the development of a set of guiding principles for the evaluation of breeding techniques by the organic sector over time. The worldwide standards of organic agriculture (OA) do not allow genetic engineering (GE) or any products derived from genetic engineering. The standards in OA are an expression of the underlying principles of health, ecology, fairness and care. The derived norms are process and not product oriented. As breeding is considered part of the process in agriculture, GE is not a neutral tool for the organic sector. The incompatibility between OA and GE is analyzed, including the “novel breeding techniques”. Instead, alternative breeding approaches are pursued based on the norms and values of organic agriculture not... |

| Organic farming systems, characterized by special attention to soil fertility, recycling techniques and low external inputs, gained increased significance in recent years. As a consequence, there is a growing demand for varieties adapted to organic and/or low input farming. The objectives of the present study were to (i) compare the testcross performance of segregating maize (Zea mays) populations under established organic (OF) and conventional farming (CF) systems, (ii) determine quantitative genetic parameters decisive for the selection response under OF vs CF conditions, and (iii) draw conclusions for breeding new varieties optimally adapted to OF. Testcross performance of four different material groups of preselected lines (90 lines per group) derived... |

| At present, agriculture faces the unprecedented challenge of securing food supplies for a rapidly growing human population, while seeking to minimize adverse impacts on the environment and to reduce the use of non-renewable resources and energy. A shift towards sustainable agricultural production entails the adoption of more system-oriented strategies that include farmderived inputs and productivity based on ecological processes and functions (Garnett and Godfray, 2012). Sustainable agricultural systems involve the traditional knowledge and entrepreneurial skills of farmers (IAASTD, 2008). System-oriented sustainable practices include organic farming and low external input sustainable agriculture (LEISA). Elements of agroecology - such as integrated pest... |

| Stakeholders of the organic movement are highly concerned about this development in the cotton sector in India. Organic farming can only present a viable alternative to conventional production if farmers have access to suitable cultivars. A national workshop on 'Disappearing non-GM cotton – ways forward to maintain diversity, increase availability, and ensure quality of non-GM cotton seed' initiated by bioRe, the Research Institute of Organic Agriculture (FiBL Switzerland) and the University of Agricultural Sciences (UAS) Dharwad presents the first agreement (Dharwad Declaration) towards safeguarding the heritage of Indian Desi cotton, maintaining genetic diversity, avoiding GM contamination as well as supporting the organic farmers with suitable... |

| The debate on the relative benefits of conventional and organic farming systems is more topical than ever. The achievements of conventional high-input agriculture were largely brought about at the cost of deteriorating soil fertility; furthermore, they were based to a large extent on fossil fuels. Developing more sustainable farming practices on a large scale is of utmost importance. However, information about the performance of agricultural production systems under organic and conventional management in tropical and subtropical regions is largely lacking. This study aimed to assess agronomic and economic data from a long-term farming systems comparison trial under semi-arid conditions in central India. Four two-year crop rotations comprising... |

| 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... |

| BackgroundWorldwide, India is the most important country for organic cotton production with 67% market share. In India, organic cotton production is challenged by 95% genetically modified (GM) cotton cultivation.Public breeding and seed multiplication were neglected and local non-GM seeds supply were eroded. With the continuous growth of the organic market it is important to maintain non-GM germplasm, to enlarge the offer of organic cultivars with a better performance that meet the demand of the market, and to rebuild the seed sovereignty of organic smallholder cotton farmers. Participatory breeding of Gossypiumhirsutumand traditionalG. arboreumcotton offers a great opportunity for developing locally adapted cultivars for increasing genetic diversity. |

| 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,... |
