RENDIMIENTO, COMPONENTES DE RENDIMIENTO Y HETEROSIS DE GERMOPLASMA DE MAÍZ ADAPTADO A VALLES ALTOS
Las variedades de maíz (Zea mays L.) introducidas de otras latitudes son una fuente de alelos favorables de utilidad en el mejoramiento genético, pero antes de ser empleados deben adaptarse a las condiciones climáticas de los ambientes de interés.

The Small Magellanic Cloud Investigation of Dust and Gas Evolution (SMIDGE): The Dust Extinction Curve from Red Clump Stars [PDF]
We use Hubble Space Telescope (HST) observations of red clump stars taken as part of the Small Magellanic Cloud Investigation of Dust and Gas Evolution (SMIDGE) program to measure the average dust extinction curve in a ~ 200 pc x 100 pc region in the ...

Abstract One of the primary objectives in freshwater aquaculture is the search for sustainable systems based on agroecological intensification. In this context, the cultivation of local species is decisive, although requiring the identification of new candidates. Malagasy aquaculture is an example of the development of such an approach.

Interacción genotipo por ambiente del rendimiento de maíz amarillo en híbridos trilineales, Perú
El uso de híbridos trilineales en los programas de mejoramiento genético de maíz (Zea mays L.) se ha incrementado en las últimas décadas, ya que cuenta con la ventaja de obtener mayor rendimiento de grano causado por la heterosis.

The experiment was conducted with the objective to evaluate the effects of fertilizer level and row spacing on soybean morphological characteristics, forage yield, and nutritive value in the highlands of Ethiopia. A factorial arrangement of randomized complete block design (RCBD) using two factors (row spacing and four fertilizer levels) containing ...
