Rapeseed‐to‐Wheat Yield Ratio in Different Production Environments and Effects on Subsequent Summer Crops Yields

Rapeseed and wheat crops were sown in a long-term rotation trial where different cropping systems were evaluated and the rapeseed/wheat yield ratio was about 55%, and higher summer crop yields were obtained after rapeseed compared with wheat.

The effect of organic and chemical fertilizers on oilseed rape productivity and weed competition in short rotation

Abstract A two-year field experiment was conducted to investigate the impact of short crop rotation and organic amendments on rapeseed yield under weed competition conditions. The primary

Global systematic review with meta-analysis reveals yield advantage of legume-based rotations and its drivers

Diversified cropping systems, especially those including legumes, have been proposed to enhance food production with reduced inputs and environmental impacts. However, the impact of legume pre-crops

Diversifying the cropping phase

Globally, growing crops in short rotation or in monoculture is common, largely in response to market trends, increasing frequency of climate trends affecting grower risk profiles (e.g. droughts,

Effect of catch crop, straw management and fertilisation on the productivity of field pea and winter wheat crop sequence

The present study aimed to determine the effect of catch crop, straw management and mineral fertilisation on the grain yield and chemical composition of field pea (Pisum sativum L.) and winter wheat

The long-term effect of legumes as forecrops on the productivity of rotation winter triticale–winter rape with nitrogen fertilisation

It is shown that legumes, as forecrops, increased the yield of WT cultivated in the second year of rotation and there is no need to use a dose of nitrogen 180 kg N ha−1 if the fore-fore-crops were indeterminate cultivars of BL or YL.

Can rotations improve management of herbicide-resistant annual sowthistle (Sonchus oleraceus) and prickly lettuce (Lactuca serriola) in lentil production systems of southern Australia?

Weed density assessments and accurate knowledge of the herbicide resistance status of target weeds should guide herbicide selection to maximize control in a subsequent crop.



Yield, yield formation, and blackleg disease of oilseed rape cultivated in high-intensity crop rotations

Results of this study emphasize that high-intensity OSR production will very likely be unsustainable over the long term associated with yield losses and increased infestation levels of blackleg disease.

Effect of Different Preceding Crops and Crop Rotations on Yield of Winter Oil‐seed Rape (Brassica napus L.)

It is argued that an increase in the incidence of fungal diseases has considerably contributed to the yield decrease of oil-seed rape in short rotations.

Impacts of high intensity crop rotation and N management on oilseed rape productivity in Germany

The results demonstrate that seed yield, oil yield and N-use efficiency all declined with an increased cropping intensity for the period 2005–2012, and emphasise the importance of crop rotation to maintain seed yield and oil yield of oilseed rape, and to maximise the response to applied N.

Crop rotation effects on yield of oilseed rape, wheat and barley and residual effects on the subsequent wheat

The results clearly reveal the importance of a favourable preceding crop for the yield performance of a crop, especially wheat and OSR.

Impact of rotation on yield and economic performance of summer crops-winter canola cropping systems.

In the southeast US, winter wheat as a double crop has proved to be economically profitable and beneficial for soil management to the farmers. W inter canola (Brassica napus L.) also has similar

Break crops and rotations for wheat

This review quantifies the yield increase, based on >900 comparisons of wheat growing after a break crop with wheat after wheat, to provide a basis for the decision to grow continuous cereal crops, strategic rotations or tactically selected break crops.

Meeting the demand for crop production: the challenge of yield decline in crops grown in short rotations

Gaps are identified in understanding of yield decline, particularly with respect to the complex interactions occurring between the different components of agro‐ecosystems, which may well influence food security in the 21st Century.

Pre-crop effects of grain legumes and linseed on soil mineral N and productivity of subsequent winter rape and winter wheat crops

It is suggested that pre-crop effects are of decreasing importance when environmental conditions for the subsequent crop improve, and fertilization of subsequent crops with mineral nitrogen should be able to compensate differences in pre-crops.
