Avaliação dos efeitos do azoto na produção de duas variedades de batata doce em três zonas de Santiago.

A b s t r a c t : A field experiment wa s conducte d in three locations on the island of Santiago ( São Domingos , Serrado and Tarrafal) to estimate the influence of different doses of Nitrogen (O, 2 1 , 4 2 , 63 Kg N/ha) applied as a m m o n i u m sulfate (NH^SO^) on the yield of t w o sweet potato varieties: 'fiegisto' (V2) and ' D j u d a m ' ( V I ) . The experimental design was a randomized complete block with 4 replications. In São Domingos the treatments average yield of Resisto was almost three times as much the treatments average yield of Djudam and in Serrado. The yield was aproximately twice as much for NO and N I and over three times as much for N2 and N3. On the other hand, Djudam produced relatively well in Tarrafal, being outperformed by Resisto only with maximum N application. There was no significant difference in yield between the t w o varieties in Tarrafal as indicated by the ANOVA test ( 9 5 % ) . However, both varieties responded positively to leveis of N in the same location

National Dry Bean Nursery and Pinto Bean Variety Demonstrations Graham County, 1991

Two bean variety studies were conducted in the southern part of Graham county in 1991. One was a replicated small plot trial in cooperation with the National Dry Bean Nursery which contained forty -one varieties from eight different commercial classes of beans. The highest yielding variety was CO-1760, a Great Northern variety which yielded 3340 pounds per acre. The second highest yielding variety was Bill-Z, a pinto variety, which yielded 3111 pounds per acre. Several other varieties of beans yielded nearly 3000 pound per acre and are potential alternative crops for the area. The other study was a pinto bean demonstration. In it, Olathe was the top yielding variety with a yield of 3260 pounds per acre with Bill-Z a close second with 3190 pounds per acre

Pinto Bean Variety Demonstration in Bonita, Graham County, 1990

Nine pinto bean varieties were tested in the Bonita area of Graham county as a follow up to the tests the previous two years. The top yield in 1990 was nearly 1700 pounds per acre compared with 3200 to 3000 for 1989 and 1988, respectively. Late planting early frost and bean rust all figured into the reduced yields. Additionally, a replicated, small plot test was planted to eleven different species of beans as diverse as garbanzo, lima and kidneys. Yield results and comments on these beans adaptability to the area are included in this report

Cátedra Preclínica de Odontología Restauradora, Argentina.El objetivo de este estudio fue analizar el comportamiento, contracción volumétrica, de diferentes resinas compuestas de fotopolimerización, expuestas a variadas condiciones de incidencia lumínica. Se tomaron volúmenes estandarizados de 7 resinas compuestas (microhíbridas y nanohíbridas y nanoparticulados) que se colocaron sobre una línea de referencia en portaobjetos, cubriéndose luego con otro y aplicando una fuerza previamente establecida. Se midió luego con un calibre electrónico la variaciones en el diámetro de la muestra bajo tres situaciones diferentes: luz ambiente (natural), luz foco (halógena), luz artificial (tubos fluorescentes) y sus combinaciones. Resultados: Se observó la mayor variación porcentual al exponer a las muestras simultáneamente a la luz ambiente, artificial y operatoria, siendo los valores más altos de reducción para las resinas compuestas Brilliant NG Coltène (Dentina) y Miris 2 Coltène (Denti-na), con -2.52% y -2.7%, respectivamente
