A QUALITATIVE CHOICE ANALYSIS OF FACTORS INFLUENCING POST-CRP LAND USE DECISIONS AgEcon
Johnson, Phillip N.; Misra, Sukant K.; Ervin, R. Terry.
The future use of Conservation Reserve Program (CRP) lands is an important agricultural policy issue. To examine the effects of factors that influence landowners' post-contract use of CRP lands, a survey of Texas High Plains CRP contract holders was conducted in 1992. This study analyzes the results of the survey using a qualitative choice model. It was found that the presence of a livestock enterprise in the current contract holder's operation increases the probability of these acres remaining in the established cover. Contract holders who value the commodity base have an increased probability of returning their acres to crop production.

A racionalidade econômica do empresário familiar. Infoteca-e
PAYES, M. A. M.; SILVEIRA, M. A. da.
Resumo: Os agricultores familiares constituem-se um segmento bastante complexo e diversificado ad setor econômico agrícola. Existem muitas modalidades de agricultores familiares, assim como existem diferentes lógicas desses agricultores quanto à utilização de tecnologias e práticas produtivas, bem como quanto ao seu relacionamento com o mercado. Deste modo devem ser tratados considerando tais diferenças, tanto no que se refere às políticas de fomento como às políticas de desenvolvimento científico e tecnológico. O presente texto objetiva discutir as disparidades acima apontadas, de modo a contribuir para o estabelecimento de estratégias para o desenvolvimento da agricultura familiar no âmbito da sua sustentabilidade, ou seja, levando-se em conta os...

A REGIONAL COMPARISON OF U.S. COTTON BASIS PATTERNS AgEcon
Seamon, V. Frederick; Kahl, Kandice H.; Curtis, Charles E., Jr..
The basis, defined as the cash price minus the futures price, is important when making marketing decisions. The cotton basis is calculated using the July futures price for six major cotton marketing regions in the U.S. for August 1993 to November 1997. Graphs of the average basis for the four complete crop years show that the basis generally followed the expected seasonal pattern. The basis tended to be weakest at harvest and to strengthen later in the crop year. However, a visual inspection showed regional differences in the seasonal pattern. Regional differences in the yearly variability in the basis were also observed. Thus, the usefulness of the average historical basis in predicting the future basis appears to differ depending on the region.

A revision of Omalanthus (Euphorbiaceae) in Malesia Naturalis
Esser, H.-J..
Omalanthus is revised for Malesia and the Solomon Islands. For this region, 13 species without subspecific taxa are accepted, namely O. arfakiensis, O. caloneurus, O. fastuosus, O. giganteus, O. grandifolius, O. longistylus, O. macradenius, O. nervosus, O. novoguineensis, O. populifolius, O. populneus, and O. trivalvis, and, as a new species, O. remotus. In addition to established synonyms, 17 species from Malesia are not accepted any more. The diagnostical importance of a peltate or non-peltate leaf base is especially doubted. Although detailed phylogenetic and biogeographical analyses were not made, the value of the established sections of Omalanthus is questioned. An alternative subdivision unites all Malesian taxa into four subgroups, each with a...

A RISK PROGRAMMING APPROACH TO DESIGNING CONTRACTS TO REDUCE NITRATE LEACHING AgEcon
Chu, Mei-Chin; Swinton, Scott M.; Batie, Sandra S..
As contractual agriculture expands, contract design offers a non-regulatory opportunity to reduce non-point source pollution. A risk programming analysis of seed corn contract designs illustrates a tractable empirical principal-agent model, and shows that grower risk preferences affect contract acceptability and efficiency at reducing nitrate leaching.

A search for RFLP markers to identify genes for aluminum tolerance in maize. Repositório Alice
TORRES, G.A.; PARENTONI, S. N.; LOPES, M.A.; PAIVA, E..
The objective of this study was to identify restriction fragment length polymorphism (RFLP) markers linked to QTLs that control aluminum (Al) tolerance in maize. The strategy used was bulked segregation analysis (BSA) and the genetic material utilized was an F2 population derived from a cross between the Al-susceptible inbred line L53 and Al-tolerant inbred line L1327. Both lines were developed at the National Maize and Sorghum Research Center - CNPMS/EMBRAPA. The F2 population of 1554 individuals was evaluated in a nutrient solution containing a toxic concentration of Al and relative seminal root length (RSRL) was used as a phenotype measured tolerance. The RSRL frequency distribution was continuous, but skewed towards Al-susceptible individuals....

A simple model for the break-up of marine aggregates by turbulent shear ArchiMer
Ruiz, Jean-eric; Izquierdo, A.
A simple model for the break-up, by turbulent shear, of marine aggregates is proposed. Three factors are considered to control the rupture of aggregates of different sizes. First, turbulence exerts stronger shear forces on bigger aggregates. Second, big aggregates are weaker than small ones because their porosity increases. Third, the rate of rupture of an aggregate is considered to be dependent on the point in the aggregate where the rupture takes place. This third factor allows the determination of the size distribution resulting from aggregate break-up. By considering these factors the model predicts the break-up rates of aggregates of different sizes and the aggregates' size-distribution resulting from this break-up. Therefore, the model represents an...
