| Sweet potato (Ipomoea batatas L.) and sweet sorghum (Sorghum bicolor L.) are promising crops for advanced biofuel production because they are better suited than corn (Zea mays L.) to low input production on small farms in the south. They can be considered advanced feedstocks only if lifecycle greenhouse gas emissions are less than 50% of basoline baseline emissions. Both sweet potato and sweet sorghum are multifunctional crops, with potential to simultaneously produce human food, animal feed, and biofuel feedstock. Kentucky State University is exploring the potential for organic production techniques and decentralized processing systems to reduce lifecycle greenhouse gas emissions of energy produced from these crops at a range of small farm scales. In 2009... |

| The use of winter peas becomes more and more common in organic agriculture. In field trials, winter pea-triticale intercrops were compared with spring peas concerning their yield performance. The differences in gross margins were calculated by using data from origin farms. Savings in seed costs (-136 €/ha) and machine costs (-13 €/ha) could be gained by replacing spring pea sole crops with winter pea-triticale intercrops. Additionally, there were yield increases of 33 % for intercropped winter peas, which resulted in an extra benefit of 378 €/ha. Aside from that, the intercropped triticale provides an extra income. |

| 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 based to a large extent on fossil fuels and largely brought about at the cost of deteriorating soil fertility. Developing more sustainable farming practices on a large scale is of utmost importance. However, information about the performance of farming systems under organic and conventional management in tropical and subtropical regions is sparse. This study presents agronomic and economic data from the conversion phase (2007-2010) of a farming systems comparison trial on a Vertisol soil in central India. A cotton-soybean-wheat crop rotation under biodynamic, organic and conventional (with... |
