An Offline Algorithm for Site-specific Nitrogen Fertilization of Winter Oilseed Rape Based on Autumnal Canopy Nitrogen Uptake
Introduction Winter oilseed rape (WOSR) is grown in Germany on approx. 1.5 million ha (Statistisches Bundesamt 2010). Almost two-thirds of this is used as renewable resource for producing bio diesel (Fachagentur Nachwachsende Rohstoffe 2011). The bioenergy policy on the EU and national level therefore have an enormous impact on the profitability of this crop. The EU Directives 2009/28/EC and 20...
متن کاملEvaluation of growth and seed yield of new winter oilseed rape (Brassica napus L.) genotypes under terminal drought stress conditions
Breeding and production of drought tolerant cultivars for arid and semi-arid area is very important. The present experiment was carried out to evaluate the effects of drought stress on seed yield and yield components of oilseed rape as well as identification of high yielding and drought stress tolerant genotypes. Eighteen new winter oilseed rape lines and commercial cultivars were evaluated und...
متن کاملEffect of Sowing Method and N Application on Seed Yield and N Use Efficiency of Winter Oilseed Rape
In northern Europe, replacing winter barley with winter wheat as the preceding crop for winter oilseed rape (Brassica napus L.; WOSR) often results in a delayed WOSR sowing and poor autumn growth. Based on data from a field experiment running in 2009/2010, 2010/2011, and 2012/2013, this study aims (i) to investigate how a delayed sowing method affects seed yield, N offtake with the seeds, and a...
متن کاملEffect of sowing date on yield and yield components of three oilseed rape varieties
In order to elucidate the effect of sowing date on oilseed rape (Brassica napus L.) yield and yield components, three varieties including Tower, Rafal and Global were sown from November 7 to December 22, 1998-99 in four dates with 15day intervals in Dezful region. A split-plot design based on randomized complete blocks with four replications was used in which levels of sowing dates and cultivar...
متن کاملLeaf Senescence, Root Morphology, and Seed Yield of Winter Oilseed Rape (Brassica napus L.) at Varying Plant Densities
In this study, the yield and yield components were studied using a conventional variety Zhongshuang 11 (ZS 11) and a hybrid variety Zhongyouza 12 (ZYZ 12) at varying plant densities. The increase in plant density led to an initial increase in seed yield and pod numbers per unit area, followed by a decrease. The optimal plant density was 58.5 × 104 plants ha-1 in both ZS 11 and ZYZ 12. The furth...
