Seed yield determination of peanut crops under water deficit: Soil strength effects on pod set, the source–sink ratio and radiation use efficiency Haro Juarez, Ricardo Javier; Dardanelli, Julio Luis; Otegui, María Elena; Collino, Daniel (Elsevier, 2008-06-10)Peanut (Arachis hypogaea L.) production in Argentina is affected by frequent and unpredictable periods of water deficit that usually overlap the critical period for pod set of early sown crops. An indirect effect of water ...
Source-sink relations and kernel weight in maize inbred lines and hybrids : responses to contrasting nitrogen supply levels Hisse, Ignacio R.; D'Andrea, Karina Elizabeth; Otegui, María Elena (Elsevier, 2019-01)Maize (Zea mays, L.) kernel weight (KW) is regulated by the source-sink relationship at the early grain-filling period, when potential kernel size is defined, and at the effective grain-filling period, when final KW is ...
Water and radiation use efficiencies in maize: breeding effects on single-cross Argentine hybrids released between 1980 and 2012 Curin, Facundo; Severini, Alan David; Gonzalez, Fernanda Gabriela; Otegui, María Elena (Elsevier, 2019-11)Water deficit has been signaled as an important determinant of grain yield (GY) gaps between potential and actual GYs. Breeding for improved water as well as solar radiation productivities is a sustainable means to reduce ...
