R.; MINGOTI, R.. Este trabalho apresenta estimativas e análise estatística da folga de produtividade (yield gap analysis) na lavoura de trigo em Minas Gerais, no contexto da expansão da produção do cereal em regiões tropicais do Brasil. Aplicou-se um método estatístico, hierárquico e adaptativo para se obter estimativas da magnitude absoluta e relativa das folgas de produtividade nas microrregiões mineiras com presença de trigo, bem como uma análise de sua evolução. Por meio de indicadores de concentração e de dinamismo, avaliaram-se mudanças individuais (em cada microrregião) e relativas (quando são comparadas entre si) ao longo do tempo. Foram identificadas trajetórias evolutivas variadas entre as microrregiões, muitas vezes sem tendência clara. Essa variabilidade é...

Crassostrea gigas and Mytilus edulis are reared in four areas along the eastern coast of Cotentin (Normandy). Every five years, a stock assessment survey, based on a stratified random sampling is carried out using aerial photographs. During September 2000, oysters bags and mussel banks random samplings have been weighed on leasing grounds and in random sampled farms in order to evaluate the overall total gross and net weights breeded (oysters 40 000 and mussels 17 000 metric tons, net weights). Age compositions of each stock in each rearing area have been computed. This last stock assessment showed that cultural regulations are less and less observed in Normandy's breeding areas. A strong increase in bag densities has been noticed since 1995. As stock...

Ano: 2001 URL: http://archimer.ifremer.fr/doc/00107/21786/19360.pdf Evaluating Vector-Virus-Yield Interactions for Peas and Lentils under Climatic Variability: A Limited Dependent Variable Analysis AgEcon Elbakidze, Levan; Lu, Liang; Eigenbrode, Sanford. This study examines the effects of climatic conditions on interactions among pea and lentil yields, pea aphid Acyrthosiphon pisum (Harris) infestations, and outbreaks of PEMV (Pea enation mosaic) and BLRV (Bean leaf roll) viruses in the Palouse region of easternWashington. The study analytically and empirically evaluates the effects of aphid outbreaks on per acre yields, implicitly including the effects of adopted pest management activities and explicitly taking into account possible effects of climatic conditions on the severity of pea aphid outbreaks. The results show that aphid outbreaks have historically decreased pea and lentil yields by approximately 5% and 7% on average respectively.

Ano: 1983 URL: http://anchan.lib.ku.ac.th/agnet/handle/001/4136 FACTORS AFFECTING THE SUPPLY OF QUALITY SPRING WHEATS: COMPARISONS BETWEEN THE UNITED STATES AND CANADA AgEcon Dahl, Bruce L.; Wilson, William W.. The demand for high quality hard wheats has been increasing. In this paper, factors affecting the supply and consistency of high quality wheats in Canada and North Dakota were compared and contrasted. Differences exist in the development and release of new varieties which affect the number and quality of hard wheats produced. Variety numbers and concentration were examined with a range of measures. Wheat area in Canada was found to be concentrated in fewer varieties than in North Dakota. These results were more apparent for durum than for hard red spring wheats. However, there was a trend toward more concentration in North Dakota and less in Canada. Protein, yield, and trade-offs were compared. Alberta appears to have a comparative advantage in the...
