This study evaluated the transcriptional profile of genes related to nitrogen (N) assimilation in coffee plants susceptible and resistant to rust fungi under N sufficiency and N suppression. For this purpose, we inoculated young coffee leaves with Hemileia vastatrix uredospores and collected them at 0, 12, 24 and 48 hours post-inoculation (HPI) to ...

Atmospheric deposition and mineral weathering are important sources of base cations in vegetated ecosystems. To assess plant preferences for weathering-fed versus atmospheric-fed mineral nutrition during different growth stages (sapling to mature), we have studied 87Sr/86Sr isotope ratios, and Ca and Sr concentrations in the vegetation, litter, org...
The concept of soil nutrient availability is still widely viewed within the framework of crop yield responses to fertilizer applications as the intermediary variable linking the rate of application of a single nutrient to the absorption of this nutrient by plants according to the pioneer work of Boussingault (1855), von Liebig (1855), and Mitscherl...

The effect of the application of reclaimed water and saline water on physiological parameters in Ocimum basilicum L. plants were studied to evaluate their adaptability to irrigation with saline water, as well as to evaluate the applicability of wastewater as a source for irrigation. Plants of O. basilicum grown under greenhouse conditions were subm...
ABSTRACT Cowpea plants produce protein-rich grains and present high yield potential when grown under irrigation and organic fertilization, enabling to substitute part of the mineral fertilizer with sewage sludge, reducing costs and generating environmental benefits. Thus, a field study about residual effect of sewage sludge fertilization on cowpea ...

Silicon, a quasi-essential element that is often associated with rigidity and hardiness is an alleviator of biotic and abiotic stresses. Lodging affects the ability of plants especially cereal plants such as rice, Oryza sativa to grow upright, thus reducing yield and increasing harvesting costs. Bending or lodging resistance could be increased by s...
Revealing belowground-aboveground relationships (BAR) is essential to drive ecological processes to address agriculture dysfunctions, especially in the management of aboveground plant diseases. Earthworms are one of the most important soil organisms involved in BAR, and silicon (Si) has been identified as a crucial element regulating aboveground pl...
ABSTRACT The objective of this study was to evaluate the effect of potassium doses on the production components of sunflower cultivars grown in the semiarid climate region. The experiment was carried out in two agricultural seasons, in 2016 and 2017, at the Rafael Fernandes Experimental Farm, Mossoró, RN, Brazil. The experimental design used was ra...
Macroalgae are important beings in their habitats, because they have great ecological relevance. In the aquatic ecosystems, they are source of nutrients and the main photosynthetic organisms. The Pacheco beach in Caucaia, a municipality in the metropolitan region of Fortaleza-CE, composes the coastal plain of the Brazilian Northeast. In this region...
The production of quality seedlings is essential for optimal growth and good crop yields during transplantation; therefore, the objective of the present investigation was to determine the effect of bacteria that promote plant growth and the management of nutrition in the physiology and growth of serrano pepper seedlings. Under greenhouse conditions...
