“…This genotype is 1 m high, has a short flowering time and has high seed yield, making it an attractive cash crop alternative for poor family farmers in the semi-arid regions of Brazil. These farmers have limited resources (land, labor, inputs and capital) and therefore face a number of setbacks which hamper their engagement in oil crop production [17].…”

“…Family farmers, who are targeted by the biodiesel policy in the northern region of Minas Gerais, are often resource constrained (i.e. land, labour and cash) (Leite et al, 2013). Thus, their engagement in the production of sunflower for the biodiesel industry could lead to potential competition with current crops with further impacts on food and feed production (Florin et al, 2012).…”

“…Sunflower (Helianthus annuus L.) has been considered a promising alternative for family farming systems, particularly in the semi-arid regions of the country. The northern region of the state of Minas Gerais is of particular interest due to its potential for sunflower cultivation, diversity of climatic zones and farming systems (Leite et al, 2013).…”

Pushed by the Brazilian biodiesel policy, sunflower (Helianthus annuus L.) production is becoming increasingly regarded as an option to boost farmers' income, particularly under semi-arid conditions. Biodiesel related opportunities increase the demand for decision-making information at different levels, which could be met by simulation models. This study aimed to evaluate the performance of the crop model OILCROP-SUN to simulate sunflower development and growth under Brazilian conditions and to explore sunflower water-and nitrogen-limited, water-limited and potential yield and yield variability over an array of sowing dates in the northern region of the state of Minas Gerais, Brazil. For model calibration, an experiment was conducted in which two sunflower genotypes (H358 and E122) were cultivated in a clayey soil. Growth components (leaf area index, above ground biomass, grain yield) and development stages (crop phenology) were measured. A database composed of 27 sunflower experiments from five Brazilian regions was used for model evaluation. The spatial yield distribution of sunflower was mapped using ordinary kriging in ArcGIS. The model simulated sunflower grain productivity satisfactorily (Root Mean Square Error ≈ 13 %). Simulated yields were relatively high (1,750 to 4,250 kg ha −1 ) and the sowing window was fairly wide (Oct to Feb) for northwestern locations, where sunflower could be cultivated as a second crop (double cropping) at the end of the rainy season. The hybrid H358 had higher yields for all simulated sowing dates, growth conditions and selected locations.

Producer organizations (POs) are often recognized as a pathway to boost rural development by enhancing farmers' access to market opportunities. Smallholder production and marketing of new crops (such as those fo r biodiesel feedstock) are constrained as farmers and buyers face high transaction costs. By investigating cases of POs outside the biofuel industry, the authors explore the extent to which POs could reduce transaction costs. The findings indicate that POs are capable of linking farmers effectively to markets in cases in which high value is added to farm products and/or farmers are highly specialized. However, the scope for POs in linking farmers to biodiesel markets is limited due to organization-specific characteristics, the low value added of the feedstock, plus multiple trade-offs with current farm activities.
