(2014)
Interannual correlation between satellite-derived sea surface temperature (SST) and surface chlorophyll a (Chl a) are examined in the coastal upwelling zone off Punta Eugenia on the west coast of the Baja California ...
Effects of soil and foliar application of soluble silicon on mineral nutrition, gas exchange, and growth of potato plants
(2013-07-01)
Silicon can alleviate biotic and abiotic stresses in several crops, and it has beneficial effects on plants under nonstressed conditions. However, there is still doubt about foliar-applied Si efficiency and Si effects on ...

To quantify the primary productivity in a fixed sampling station at the Barra Bonita Reservoir, monthly sampling from July/03 to August/04 were performed in three different depths in the euphotic ...
Photosynthetic pigments, nitrogen status, and flower behavior in eggplant exposed to different sources and levels of potassium
(2012)
The aim of this study was to investigate (i) the influence of different sources and levels of potassium on photosynthetic pigments, (ii) measure nitrogen status in leaf, (iii) evaluate flower behavior in eggplant (Solanum ...
Nutrition and production of Helianthus annuus in a function of application of leaf silicon
(Taylor & Francis Inc, 2019-01-20)
Silicon (Si) is important as it increases plant tolerance to abiotic stresses. However, studies on in foliar fertilization are still scarce. The objective of this research was to evaluate the effect of foliar application ...
Silicate fertilization potentiates the nodule formation and symbiotic nitrogen fixation in soybean
(Univ Federal Goias, 2018-07-01)
The application of silicon (Si) to the soil can increase the grain yield of the soybean crop by improving the nitrogen biological fixation, due to its beneficial effect on the Bradyrhizobium-soybean symbiosis. This study ...
Monitoring of aquaculture in continental reservoirs using the trophic status index
(Univ Federal Mato Grosso, 2019-05-01)
Aquaculture is the fastest growing activity among food production sectors, however, its practice can cause environmental impacts, in case if a monitoring plan is not applied. The objective of the present study was to ...
Nutrition and physiology of hybrid Eucalyptus urograndis in soil fertilized with sewage sludge
(2020-01-01)
Sewage sludge is a residual pollutant product from the treatment of urban effluent and must be adequately processed before final disposal in order to avoid environmental contamination. The use of sewage sludge in agricultural ...
Silicon Supplied Via Roots or Leaves Relieves Potassium Deficiency in Maize Plants
(2021-01-01)
Purpose: The aim of this study was to determine whether silicon (Si) supplied via nutrient solution or foliar spray is nutritionally and physiologically efficient in mitigating potassium (K) deficiency in maize plants. ...
