Effect of zinc application strategies on maize grain yield and zinc concentration in mollisols
(Taylor and Francis, 2020-11-12)Maize (Zea mays L.) is highly susceptible to zinc (Zn) deficiency. Different application strategies (AS) can be utilized to improve grain yield (GY) and quality (Zn biofortification) by combining Zn fertilizer rate, source, ... -
Morphological and molecular variability of wild diploid and polyploid populations of Chrysolaena flexuosa (Sims) H. Rob: relevance for ornamental breeding
(Elsevier, 2020-01)Chrysolaena flexuosa is a South American species of ornamental interest, whose variability has not been explored. The objective of this work was to perform joint analyses of morphological and molecular traits in seven ... -
Efecto de la proximidad de la diversidad vegetal asociada al cultivo de soja sobre el control natural de Rachiplusia Un (Lepidoptera: Noctuidae) en Balcarce, sudeste de la provincia de Buenos Aires
(Facultad de Ciencias Agrarias, Universidad Nacional de Mar del Plata, 2021-03)Rachiplusia nu es la defoliadora principal del cultivo de soja en el sudeste bonaerense y sus poblaciones son controladas por parasitoides y predadores, entre otros factores. En los agroecosistemas, la biodiversidad ... -
