Inter-plant competition for resources in maize crops grown under contrasting nitrogen supply and density: Variability in plant and ear growth
(Elsevier Science, 2011-04)
Increased plant population density in irrigated and fertilized maize crops enhances plant-to-plant variability since early vegetative stages, because the most suppressed individuals of the stand intercept less radiation ...
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 ...
PLANT DENSITY AND NITROGEN FERTILIZATION ON COMMON BEAN NUTRITION AND YIELD
(Univ Fed Rural Semi-arido-ufersa, 2017-07-01)
The objective of this work was to evaluate the effect of plant densities and sidedressed nitrogen (N) rates on nutrition and productive performance of the common bean cultivars IPR 139 and Perola. For each cultivar, a ...
Comportamento de cultivares de cafeeiro em diferentes densidades de plantio
(2005-12-01)
This experiment was developed at Adamantina, west region of the State of São Paulo, Brazil, during May 1995 to June of 2000. The plant growth and productivity of two coffee cultivars Catuaí Amarelo IAC 47 and Obatã IAC ...

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 ...
Influence of plant height and of leaf number on maize production at high plant densities.
(Pesquisa Agropecuaria Brasileira, Brasilia, v.33, n.3, p.297-306, mar. 1998., 1998)
Adequate plant densities to increase agricultural rice yield
(Univ Central Marta Abreu Las Villas, 2021-01-01)
The use of adequate plant densities can be a key and important factor to increasing rice productivity (Oryza sativa L.). Therefore, the objective of this study was to investigate the influence of four population densities ...
