Nitrogen redistribution to sorghum grains as affected by plant competition
(Springer, 1993-10-01)
An experiment was conducted to study nitrogen absorption and translocation in grain sorghum plants during their reproductive growth. Sorghum was grown in four row spacings: 50 and 70 cm in single rows, 80 and 120 cm in ...
Increasing population density reduces soybean yield components and productivity
(2021-01-01)
Studies addressing the interaction of different spatial arrangement in soybean are needed in order to achieve management that leads to higher grain yield associated with rational seed use. The objective of this work was ...

(Pesquisa Agropecuaria Brasileira, Brasilia, v.33, n.3, p.297-306, mar. 1998., 1998)
Microhabitat and plant structure of Batrachospermum (Batrachospermales, Rhodophyta) populations in four streams of São Paulo State, southeastern Brazil
(1997-12-01)
Microhabitat and plant structure of seven Batrachospermum populations (four of Batrachospermum delicatulum (= Sirodotia delicatula), one of Batrachospermum macrosporum and two of the 'Chantransia' stage), including the ...

(2021-01-01)
The genus Aldrovanda is a Palaeogene element containing a single extant species, Aldrovanda vesiculosa L. This aquatic carnivorous herb has a very wide range of distribution, natively covering four continents; however, it ...
ASIAN SOYBEAN RUST INTEGRATED MANAGEMENT POTENTIAL: DISEASE SEVERITY, PLANT DEVELOPMENT AND YIELD COMPONENTS, CULTIVAR MG/BR-46 (CONQUISTA)
(Univ Federal Uberlandia, 2014-06-01)
Soybean rust caused by Phakopsora pachyrhizi Sydow & P. Sydow is one of the major diseases of the soybean crop. The aim of this study was to evaluate the effects of sowing dates, plant populations and reduced doses of ...
Sowing operation direction and population densities in corn growing
(Univ Federal Campina Grande, 2019-03-01)
Among the factors that may influence corn yield are sowing operation direction and plant population, since they alter the shade index between crop rows, and consequently the efficiency of interception of the photosynthetically ...
Arranjo de plantas para diferentes híbridos de Milho
(2011-09-19)
Changes recently introduced to maize genotypes have made necessary to reassess the management practices recommendations for this culture, among them the plants spatial arrangement. This study was carried out to evaluate ...

(Wiley-Blackwell Publishing, Inc, 2009-05-01)
Lychnophora pinaster Mart. (Asteraceae) is a Brazilian medicinal plant, extensively employed in popular medicine as an anti-inflammatory, analgesic and healing agent. Thirteen polymorphic microsatellite markers were developed ...
Narrow row spacing and high plant population to short height castor genotypes in two cropping seasons
(Elsevier B.V., 2012-01-01)
Castor plant (Ricinus communis L.) produces a very important oil for chemical and biofuel industries. However, doubts remain about what the best plant arrangement is to obtain the maximum yield of seeds and oil from short ...
