| Optimal fertilisation ensures that the current rapeseed varieties and reach their full yield potential. Practical recommendation • In conventional cultivation, the nitrogen uptake of winter oilseed rape amounts to 140 kg N per ha for a yield expectation of 35 dt per ha. In organic agriculture, about 100 kg suffice for a yield expectation of 20-25 dt. • The ideal time for cultivating oilseed rape is after grass-clover or legumes. After grains, apply about 30 tonnes per ha of manure or manure compost before cultivating rapeseed. • In dry conditions in spring, an early single application of nitrogen is preferable to two smaller applications. In the case of slurry with a low N content, two applications are often required because maximum of 40 m3 of slurry... |

| 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... |
