Provedor de dados: 5
Autores: Bonnet, Marc; Troadec, Jean-paul.
Bivalve farming is in France a major economical activity, which development was initiated in the mid of last century. It occupies nowadays 24 000 ha of seabottom, leased from the French State, and production figures are above 100 000 tonnes for cupped oyster and 40 000 tonnes for mussel ; these made a gross value of 1 300 millions francs in 1983. Moreover, it shows potential for promising development, by expanding to new areas, especialy in deep sea, or by introducing new species, such as the short neck clam, which production has just reached significant level (300 T in 1984). Long age and success of this cultivation activity come from the important advantages related to the biology and ecology of bivalves: food naturaly available, and of no use by another...

Agricultural and economic characterization of guava production in Brazil
Provedor de dados: 94
Autores: Vitti,Karine Alessandra; Lima,Lilian Maluf de; Martines Filho,João Gomes.
Abstract  This study was designed to analyze the relationship between guava crop production variables in the Matão region of central São Paulo, Brazil, and to better understand the economic importance of this crop to its growers. Data were obtained through a questionnaire applied during interviews with guava growers and after the data collection, statistical analyzes were made using Chi-Square hypothesis tests. Analysis results indicate a distinct association between the variables variety and plant age, between variety and number of plants per hectare, andbetween number of plants per hectare and yield, while no association was found between yield and variety. The Paluma guava variety spaced seven meters by five meters apart and pruned throughout the entire...
