Nitrogen fertilization, plant density and maize yield cropped under no-tillage systemFertilização nitrogenada, densidade de plantas e rendimento de milho cultivado no sistema plantio direto
(2011-01-01)
In maize (Zea mays L.), the inadequate nitrogen supply and planting density are considered limiting factors to the grain yield. The objective of this study was to evaluate the influence of different nitrogen levels and ...
'Ray Ruby' Grapefruit Affected by Huanglongbing I. Planting Density and Soil Nutrient Management
(Amer Soc Horticultural Science, 2020-09-01)
Huanglongbing (HLB), or citrus greening disease, affects practically all fruitbearing trees in commercial citrus orchards in Florida with no cure identified yet. High-density plantings and enhanced nutritional programs ...
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 ...
Upland rice growth and mineral nutrition as affected by cultivars and sulfur availability
(2013-01-01)
A better understanding of the differential growth of upland rice (Oryza sativa L.) cultivars with increasing soil S availability could help improve rice yield under upland conditions. The objective of this study was to ...
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 ...
Nitrogen Sources and Rates Effect on Yield, Nutritional Status, and Yield Components of Sunflower
(2017-08-06)
Due to the high levels of crude protein in the achene, sunflower (Helianthus annuus L.) is one of the main oilseeds grown worldwide, particularly for the oil and meal production for animal feed. Despite these advantages, ...
Safflower (Carthamus tinctorius L.) yield as affected by nitrogen fertilization and different water regimes
(2017-01-01)
Due to its origin and hardiness, safflower is usually cultivated in low-fertility soils with few inputs and no irrigation. In Brazil, little is known about its response to nitrogen (N) and irrigation. This study was carried ...
Plant physiology in South America: diagnostics and perspectives
(2015-06-01)
This is a short text about a lecture I gave during the XV Congress of the Argentinian Society of Plant Physiology, in Mar del Plata, in September 2014. In this Opinion, I show some scientometrics of science and plant science ...
Morphological characters, yields and active principles in wild and cultivated accessions of the Chilean medicinal plant Buddleja globosa Hope

Effects of superficial liming and silicate application on soil fertility and crop yield under rotation
(2013-03-01)
Soil acidity and low natural fertility are the main problems for grain production in Brazilian 'cerrado'. Although lime has been the most applied source for soil correction, silicate may be an alternative material due to ...
