Viabilidade econômica do cultivo da alface crespa em monocultura e em consórcio com pepino

The protected culture, among other advantages, made possible to diminish the seasoning in offers and to improve the quality of vegetables. However, one consists in technology of high cost, that it may be attenuated with the increase in the efficiency of the use of the protected area, proportionated for the intercropping. The experiment was carried out at greenhouse at UNESP, Jaboticabal-SP, in the period of August and November of 2005, with the aim of evaluating the operational cost (COT) and the profitability of the crisphead lettuce "Veronica" (Lactuca sativa L.) in monoculture and in intercropping with the Japanese cucumber "Hokushin" (Cucumis sativus L.), in protected environment. The main cost items analyzed were the operational cost, the agricultural amendments and the materials cost. For the crisphead lettuce in monoculture and in intercropping, the COT was R$ 696,37 and R$ 295,06/614,4 m(2) respectively and the productivity was 822.53 and 890.78 kg/614,4 m(2). In monoculture and in intercropping the gross incomes were R$ 489,93 and R$ 452,39/614,4 m(2) respectively. It was verified a loss of R$ 206,44/614,4 m(2) in the crisphead lettuce monoculture and an operational profit of R$ 157,33/614,4 m(2) in protected environment when in intercropping with cucumber.

Adubação nitrogenada e fosfatada no desenvolvimeno de mudas de uvaia (Eugenia uvalha)

Considering the reduced number of works with fertilization of Eugenia uvalha in national literature and being overcome as base the results of the research with fertilization of other fruitful ones, the present work had as objective to study the effect of nitrogen fertilization and phosphorus, in the culture of the Eugenia uvalha. The work was lead in the Department of Agriculture of the Federal University of Lavras, Lavras - MG, in the first semester of 2005. The experiment was adopted the experimental delineation of randomized blocks in factorial project 4 X 4, with four repetitions and 5 plants for parcel, having been 4 doses of phosphorus: 0 kg m(-3); 2,5 kg m(-3); 5,0 kg m(-3); 10,0 kg m(-3); using itself as seasoning source the triple superphosphate. Already for nitrogen, the applications proceeded from 10 in 10 days had been used 4 doses in covering being, had been carried through 4 applications. The applications consisted of a solution with urea, in the doses: 0; 0,8; 1,6 e 3,2 Kg m(-3), in each application had been added to the polyethylene bags, 20 mL of solution contend the N. had been evaluated the following characteristics: height of the dumb one (cm); root length (cm); leaf number; dry substance of the root and the aerial part (g). For the production of changes of Eugenia uvalha of quality, incorporation to the substratum of up to 1,30 kg m(-3) of P(2)O(5) sends regards to it.

Behavior of the wild coriander (eryngium foetidum L.) in subtropical conditions

The adaptability of wild coriander (Eryngium foetidum L.) a seasoning and medicinal herb indigenous of the Amazon region was evaluated in a subtropical city of Sao Paulo, Brazil. Germination of seeds was extremely irregular with the first seeds germinating 10 days after the sowing, but the process lasted 90 days. The exploitation of this specie is possible in subtropical conditions without interruption of production but further study on the feasibility elimination of seed and flower are necessary to permit a greater yield of foliage.

Metacercárias de Diplostomum (Austrodiplostomum) compactum Lutz, 1928 (Digenea, Diplostomidae) em peixes do rio Paraná, Brasil. Prevalência, sazonalidade e intensidade de infecção

This paper aims at evaluating the occurrence of Diplostommn (Anstrodiplostomum compactum (Digenea: Diplostomatidae) in the eyeball of Plagioscion sqnamosissimus (corvina) and Cichla ocellaris (tucunaré), monthly captured in Paraná river, Presidente Epitácio, state of São Paulo, Brazil. From 61 corvinas under analysis, 56 of them contained parasites (92%) with intensity rate of 42.0 host parasites. From an amount of 81 tucunarés, 45 contained parasites (55%) with intensity rate of 9.3 parasites. Corvinas showed prevalence from 71 to 100% with the highest intensity rates (103.3 and 106.9) from February to March, 2001. Comparatively, the tucunaré showed the highest prevalence from November 2000 (90%) to February 2001 (80%). The tucunaré highest intensity rates occurred on September, 2000 (12.7), December, 2000 (12.2) and February, 2001 (16.1). Metacercariae showed a hollow womb body and a posterior region of a sinuous conic protuberance, an oral sucker smaller than the acetabulae, a simple acetabulae located in the pre-equatorial region of helminto. A short pre-pharynx followed by a muscular pharynx, genital pore next to acetubulae. Corvina metacercariae presents 1.434,0 μm (880 to 1.840) long by 611.2 ± 93.4 μm (400 to 792) wide. Tucunaré metacercariae, 1.462.4 μm (960 to 2.480) by 710.8 μm (560 to 960). Authors confirmed corvina great susceptibility to Diplomastum and the relationship between the parasitism and the aquatic and climatic parameters.
