A comparison of hypothetical survey rankings with consumer shopping behavior and product knowledge AgEcon
Grebitus, Carola; Colson, Gregory; Menapace, Luisa.
Hypothetical surveys are commonly used to elicit consumer behavior to guide product development, marketing, and labeling strategies. However, despite the prevalence of surveys in consumer food studies, previous work has not assessed the relationship between hypothetical responses and actual consumer behavior in real-world purchase situations.We explore whether attributes cited by consumers in surveys as being important to them when making decisions indeed factor into their product decision process in real-world markets. Evidence from a point of sale study of 702 pork purchasers indicates that there is a strong correspondence between hypothetical survey ratings and actual shopping behavior.

A COMPARISON OF ORGANIC AND CHEMICAL FERTILIZERS FOR TOMATO PRODUCTION Organic Eprints
Kochakinezhad, Hamed; Peyvast, Gholam-Ali; Kashi, Abdol-Karim; Olfati, Jamal-Ali; Asadi, A..
Tomato (Lycopersicon esculentum Mill.) is one of the most popular and versatile vegetables in the world, and organic production with a high yield and desirable quality is a target of many producers. The effect of four different fertilizers (chemical, municipal solid waste compost, cattle manure, and spent mushroom compost) on four commercial tomato cultivars (Redstone, Flat, Peto Pride and Chief) was assessed in this research. The highest yield was obtained with the Chief cultivar when fertilized with chemical fertilizer and the lowest value was obtained with Peto Pride fertilized with 20 tonnes per hectare (t/ha) of cow manure. The difference between the two classes of fertilizers (organic and chemical) was not very high so that organic fertilizers are...

A comparison of RAPD and ISSR markers reveals genetic diversity among sweet potato landraces (Ipomoea batatas (L.) Lam.) - doi: 10.4025/actasciagron.v34i2.12616 Agronomy
Moulin, Monique Moreira; Universidade Estadual do Norte Fluminense Darcy Ribeiro; Rodrigues, Rosana; Universidade Estadual do Norte Fluminense Darcy Ribeiro; Gonçalves, Leandro Simões Azeredo; Universidade Estadual do Norte Fluminense; Sudré, Cláudia Pombo; Universidade Estadual do Norte Fluminense Darcy Ribeiro; Pereira, Messias Gonzaga; Universidade Estadual do Norte Fluminense Darcy Ribeiro.
Small farmers have played an important role in maintaining genetic resources of traditional varieties. Collecting and characterizing germplasm, especially landraces and heirloom varieties, are strategic activities that would create a knowledge base describing the traditional varieties of a given region and reduce the risk of genetic erosion. The objectives of this work were as follows: collect sweet potato roots from rural properties and local markets in Rio de Janeiro State, Brazil; characterize the accessions using RAPD and ISSR molecular markers, comparing the efficiency in discrimination of these two types of molecular markers; and estimate the genetic variability of the population. Fifty-nine samples from rural properties and 19 from local markets...

A Comparison of Traditional and Copula based VaR with Agricultural portfolio AgEcon
Mandal, Maitreyi; Lagerkvist, Carl Johan.
Mean-Variance theory of portfolio construction is still regarded as the main building block of modern portfolio theory. However, many authors have suggested that the mean-variance criterion, conceived by Markowitz (1952), is not optimal for asset allocation, because the investor expected utility function is better proxied by a function that uses higher moments and because returns are distributed in a non-Normal way, being asymmetric and/or leptokurtic, so the mean-variance criterion cannot correctly proxy the expected utility with non-Normal returns. Copulas are a very useful tool to deal with non standard multivariate distribution. Value at Risk (VaR) and Conditional Value at Risk (CVaR) have emerged as a golden measure of risk in recent times. Though...

A Comprehensive Evaluation of USDA Cotton Forecasts AgEcon
Isengildina-Massa, Olga; MacDonald, Stephen; Xie, Ran.
This study evaluates all USDA cotton supply and demand estimates for the United States and China (including unpublished price forecasts) from 1985/86 through 2009/10 for accuracy and efficiency. Results reveal that at every stage of the forecasting cycle forecast smoothing was the most widespread and persistent type of inefficiency observed in most U.S. variables. Correlation with past errors indicated the tendency to repeat past errors in most cases. Tendency to overestimate growth was also found. Bias was uncommon and limited to several cases of overestimation of China’s exports and U.S. price and underestimation of China’s domestic use. While forecasts of China’s imports and endings stocks improved, U.S. price and ending stock forecast errors became...

A concept for the viticulture of 'tropical wines'. Repositório Alice
TONIETTO, J.; PEREIRA, G. E..
At worldwide level, the classical viticulture produces wines is almost all places in different climate types, where it is possible to obtain only one harvest per year. In these conditions, bud burst in vines occurs as a result of temperature raising at the end of the winter?beginning of spring. With the development of the vegetative cycle, grapes arrive to maturity/harvest period at the end of the summer?beginning of the fall season. After the fall of the leaves, vines undergo a dormant period with a vegetative repose (condition found also in some intertropical producer regions). A lot of grapes are produced for a long-time in the intertropical zone, but only a little part is used to winemaking. Considered a challenge in the past, to produce quality wines...

A conservationist approach on environmental diagnosis of ground use in the Iguatemi river basin, Mato Grosso do Sul State, Brazil - doi: 10.4025/actascibiolsci.v34i3.9001 Biological Sciences
Souto, Marco Antonio Gomes; Instituto Reserva Natural.
Landscape Ecology is a contemporary approach in conservation studies in which, coupled to the development and use of GIS-based tools, provides new methods for the analysis of forest fragments. Based on these new approaches, the environmental assessment of ground use in the Iguatemi river basin Mato Grosso do Sul State, Brazil is provided through conservation-based flora and ecology aspects. A regional map of ground use with field-collected data using Rapid Ecological Assessment methodology and digital satellite images was prepared. AER analysis showed a highly impacted region featuring intense transformation in ground use with a conversion of 87% of native forest into grazing and agriculture land. The general situation is inconsistent with APA guidelines,...

A controversy re-visited: Is the coccinellid Adalia bipunctata adversely affected by Bt toxins? Organic Eprints
Hilbeck, Angelika; Mc Millan, Johanna M.; Meier, Matthias; Humbel, Anna; Schläpfer-Miller, Juanita; Trtikova, Miluse.
Background: In 2008/2009, Schmidt and colleagues published a study reporting lethal effects of the microbial Bt toxins Cry1Ab and Cry3Bb on the coccinellid biological control organisms Adalia bipunctata. Based on this study, in concert with over 30 other publications, Mon810 cultivation was banned in Germany in 2009. This triggered two commentaries and one experimental study all published in the journal ‘Transgenic Research’ that question the scientific basis of the German ban or claim to disprove the adverse effects of the Bt toxins on A. bipunctata reported by Schmidt and colleagues, respectively. This study was undertaken to investigate the underlying reasons for the different outcomes and rebuts the criticism voiced by the two other commentaries....

A cow type for concentrate-free feeding systems - What characteristics does it display? Organic Eprints
Holinger, Mirjam.
Feeding of concentrates to ruminants in organic farming in Switzerland is questionable due to several aspects: (i) suitability for ruminants, (ii) land use change caused by soy cultivation, (ii) organic principles of closed circuits, and (iv) ethical considerations when ruminants directly compete with human nutrition. In the past decades breeding strategies in the dairy sector focused primarily on milk production which led to increased energy requirements. A reduction of concentrates in the ration may thus lead to a more negative energy balance and may be detrimental for health and fertility. Published genotype x feeding system interactions suggest that different breeds, strains or genotypes react differently to different levels of feeding. The aim of...

A crise europeia e a agricultura brasileira. Repositório Alice
ALVES, E. R. de A..
Se a crise europeia ficar ali restrita, sem impactos ou com pequenos impactos nos países para os quais exportamos, seus efeitos no Brasil estarão relacionados com a retração da demanda daqueles produtos que para lá exportamos, principalmente carnes e grãos. Como a Europa é também grande exportadora, se a crise reduzir sua produção, então nos beneficiaremos se formos ágeis em ocupar o espaço que se abrirá.
