Preliminary study on parasitism of aphids (Hemiptera: Aphididae) in relation to characteristics of alfalfa fields (Medicago sativa L.) in the Argentine Pampas
(Elsevier, 2012-09-12)Alfalfa is a perennial crop and is one of the most relevant forage resources for cattle in the Argentine Pampas, with aphids (Hemiptera Aphididae), one of the main pest insects in alfalfa, being frequently attacked by a ... -
Water table depth affects persistence and productivity of alfalfa in Central Argentina
(Elsevier, 2019-04)Alfalfa (Medicago sativa L.) is one of the most sown perennial legumes in the world. Water table depth can be both an opportunity and a threat for this crop. In this study we analyzed 20 years of field experimental data ... -
Yield components, light interception and radiation use efficiency of lucerne (Medicago sativa L.) in response to row spacing
(2013-02)Lucerne sowing is characterized by a rectangular spatial arrangement, i.e. greater distance between sowing rows than between plants in the row. Therefore, the reduction of row spacing generates more square spatial arrangements ...
