Breeding and quality analysis of rapeseed AgEcon
Chudleigh, Peter D..
This study is an ex-post, economic assessment of two projects supported by ACIAR and concerned with the breeding and quality analysis of rapeseed in Australia and China. These projects were carried out sequentially with the first one commencing on 1 July 1986. The second one was completed on 30 June 1991. The projects were essentially an exchange of knowledge and germplasm of rape (Brassica napus) between plant breeders in Australia and China. The projects resulted in the release of varieties of rape that yielded improved seed in Australia, China and other developed and developing countries. An economic evaluation of these projects was made in 1991 and the results published in Chudleigh (1991). Assumptions made in the 1991 analysis have now been updated....

Costs of Processing Genetically Modified Organisms: Analysis of the Rapeseed and Corn Industries AgEcon
Gawron, Jana-Christina; Theuvsen, Ludwig.
Die zunehmende Verbreitung gentechnisch veränderter Organismen (GVO) wirft die Frage nach möglichen wirtschaftlichen Konsequenzen auf. Die parallele Existenz von GVO- und GVO-freier Ware im Markt kann mit Kosten- und Nutzeneffekten verbunden sein und spielt somit aus betriebswirtschaftlicher Sicht eine wachsende Rolle für die Unternehmen der Ernährungswirtschaft. Vor diesem Hintergrund wurde im Herbst 2006 eine empirische Studie durchgeführt, um am Beispiel Raps und Mais die Strategien deutscher Lebensmittelverarbeiter im Umgang mit GVO sowie mögliche Zusatzkosten, die sich aus der zunehmenden Verbreitung von GVO ergeben können, zu ermitteln.

Effects of rapeseed meal-glucosinolates on thyroid metabolism and feed utilization in rainbow trout ArchiMer
Burel, Christine; Boujard, Thierry; Kaushik, Sadasivam; Boeuf, Gilles; Mol, K; Van Der Geyten, S; Darras, V; Kuhn, E; Pradet Balade, B; Querat, B; Quinsac, A; Krouti, M; Ribaillier, D.
Two rapeseed meals (RM1 and RM2), containing glucosinolates at a concentration of 26 and 40 mumol/g, respectively, were incorporated at increasing levels (10, 20, and 30% for RM1 and 30 and 50% for RM2) in diets of juvenile rainbow trout. Disturbances in the thyroid axis appeared after 14 days of feeding (with a dietary incorporation level of 10%). The dietary supplementation with T-3 or iodine induced an increase in plasma T-3 levels, compared to that in fish fed the RM diets, and reduced the deleterious effect of RM on growth. When trout were reared in seawater, there was also a slight increase in thyroid hormone levels. TSH treatment had no effect on the thyroid hormone plasma levels. The incorporation of 30% of RM1, which induced a lower dietary...

EUROPEAN RAPESEED AND FOSSIL DIESEL: THRESHOLD COINTEGRATION ANALYSIS AND POSSIBLE IMPLICATIONS AgEcon
Ziegelback, Martin; Kastner, Gregor.
For European operators of biofuels plants there are not many hedge vehicles available to hedge operational margins. Cross hedges for rapeoil (with the rapeseed futures contract) and RME (with the NYMEX diesel futures contract) could be useful instruments. We use recent developments on threshold cointegration approaches to investigate if asymmetric dynamic adjusting processes exist among rapeseed and diesel prices. The results suggest that a threeregime threshold cointegration model suitably explains the dynamics of the data.

Implementation of monitoring for genetically modified rapeseed in Serbia Electron. J. Biotechnol.
Nikolic,Zorica; Vujakovic,Milka; Jeromela,Ana Marjanovic; Jovicic,Dusica.
Genetically modified (GMO) rapeseed (Brassica napus) is not grown commercially in European Union, but several lines have been approved for production and use as food and feed. A case-specific monitoring of herbicide-tolerant rapeseed, events RT73, RF3 and T45 was established by Ministry of Agriculture of Republic of Serbia. The objectives of the present study were to introduce methods for detection of herbicide-tolerant GM oilseed rape, investigate occurrence and monitor the presence of GM rapeseed in seed and the feed products, as well as to develop a protocol for quantification. The study was based on 48 samples, rapeseed (33) and feed (15) products, imported from EU countries (Germany, Belgium, France, Czech Republic, Austria) and from domestic market....

Infestation of weed species in pre-planting of soybean in succession to winter crops Planta Daninha
Concenço,G.; Silva,C.J.; Tomazi,M.; Correia,I.V.T.; Souza,N.C.D.S.; Andres,A..
This study aimed to evaluate different crops and plant species planted after soybeans for one year, in terms of their potential to inhibit the occurrence of weed species. The following crops that were planted as second crop after soybeans were evaluated: (1) corn (Zea mays) planted at spacing of 90 cm between rows, intercropped with Brachiaria ruziziensis in the inter-rows; (2) sunflower (Helianthus annuus); (3) crambe (Crambe abyssinica); (4) radish (Raphanus sativus); (5) rapeseed (Brassica napus); and (6) winter fallow - no plantation after soybeans. Phytosociological characterization of weed species was carried out at the pre-planting of soybeans in the following cropping season. Estimations of relative abundance, relative frequence, relative dominance...

Influence of lupin and rapeseed meals on the integrity of digestive tract and organs in gilthead seabream (Sparus aurata L.) and goldfish (Carassius auratus L.) juveniles ArchiMer
Omnes, Marie-helene; Silva, Francisco; Moriceau, Jacques; Aguirre, P.; Kaushik, Sadasivam; Gatesoupe, F. J..
Two rearing trials were conducted to evaluate the effects of dietary lupin (LM) and rapeseed (RM) meals in gilthead seabream (Sparus aurata L.) and goldfish (Carassius auratus L.) juveniles. Each plant meal was incorporated at the rate of 200 g kg−1 in two distinct diets, which were compared with a fishmeal-based diet as control. After 1 month, the two plant diets did not influence the whole body growth, but the digestive systems were affected. The splenosomatic index was reduced with two plant meals in goldfish and with RM in seabream. The hepatosomatic index was only reduced in LM-fed seabream. Cellular characteristics were also affected. The largest liver cells were observed in RM-fed goldfish suggesting changes in metabolic function. The LM and RM...

MEAT TRADE LIBERALIZATION AND SOYBEAN-RAPESEED COMPETITION IN THE JAPANESE MARKET AgEcon
Persaud, Suresh Chand; Chern, Wen S..
This study identifies variables which increase Japan's imports of canola (soybeans) at the expense of soybeans (canola), and quantifies their impacts by estimating an import demand model. A key finding is that lower Japanese meat production tends to increase rapeseed imports while lowering soybean imports. Thus, Canada benefited from U.S. and Australian efforts to open Japan's market for imported beef, since the vast majority of Japan's canola imports are from Canada.

Cui,Cui; Xie,Xurong; Wang,Liu-Yan; Wang,Rui-Li; Lei,Wei; Lv,Jun; Chen,Liuyi; Gao,Huan-Huan; Ye,Sang; Huang,Linya; Zhou,Qing-Yuan.
ABSTRACT: Herbicide application is an effective weed control method for mitigating crop yield loss; however, herbicide overuse can cause toxicity in non-target plants. The present study evaluated the effects of glufosinate at recommended dose for agricultural application (0.45 kg ha-1) and at overuse dose (0.90 kg ha-1) glufosinate application on photosynthetic performance and nitrogen assimilation of the rapeseed varieties D148 and Zhongshuang 11 (ZS11). Both glufosinate concentrations significantly decreased the content of chlorophyll and nitrogenous compounds, except free proline, and the activity of glutamine synthetase and glutamate synthase, and increased the activity of glutamic acid dehydrogenase in both varieties. When the concentration of...

Potential Adoption of Genetically Modified Rapeseed in France, Effects on Revenues of Farmers and Upstream Companies: an ex ante evaluation AgEcon
Desquilbet, Marion; Lemarie, Stephane; Levert, Fabrice.
In this paper, we conduct an empirical investigation of potential adoption of herbicide-tolerant (HT) genetically modified (GM) rapeseed in France. Our aim is to study ex ante the potential impact of their adoption in France, in terms of adoption level, economic gains, and distribution of these gains between farmers and input suppliers. We use French survey data about current plant protection practices, in order to compute pesticide costs with conventional (i.e., non GM) crops for individual farms. Then, based on results of technical studies about GM variety trials in France, we compute a predicted pesticide cost with the GM variety. Next, we study adoption rates and gains or losses of farmers (adopters and non adopters) and upstream companies (sellers of...

Response of rapeseed to nitrogen fertilisation in a mediterranean environment IPB - Escola Superior Agrária
Rodrigues, M.A.; Almeida, Arlindo; Ferreira, J.; Ribeiro, T.; Arrobas, Margarida.
Portugal needs urgency to increase the production of vegetable oils to be able to meet the mandatory 10% minimum target to be achieved by all EU member states for the proportion of biofuels in petrol and diesel consumption by 2020 (Directive 2009128/EC). Rapeseed oil is the main raw material used in Europe for the manufacture of biofuels. Portugal, however, does not produce rapeseed oil, in spite of some studies having indicated that there are favourable ecological conditions to do this throughout the country [I, 2]
