Silicon and salicylic acid in the physiology and yield of cotton
(Journal Of Plant Nutrition, 2019-03-16) [Artigo]
Silicon (Si) and salicylic acid (SA) foliar applications can benefit cotton yield especially if there is stress during cultivation. The objective of this study was to evaluate the foliar application of Si and SA on the ...
Effects of boron omission and foliar fertilization on nutrition efficiency and production of Cowpea
(HortScience, 2018-11-01) [Artigo]
This study aimed to evaluate the effects of boron (B) omission on cowpea nutrition and to compare the impact of foliar B fertilization with and without sorbitol on cowpea growth, nutritional status, and B uptake. Two trials ...

These systems of soil use and management are very important in carbon supply and stability of aggregates, because affect directly culture yields. The aim of this project is to evaluate the carbon supply and stability of ...
Amplification of gibberellins response in tomato modulates calcium metabolism and blossom end rot occurrence
(Scientia Horticulturae, 2019-02-27) [Artigo]
Blossom end rot is one of the main physiological disorders of the tomato crop. Usually, the blossom end rot (BER) occurrence is associated with fruit calcium (Ca2+) deficiency; however, increasing evidence of Ca2+ disorders ...
Short-term impacts of high levels of nitrogen fertilization on soil carbon dynamics in a tropical pasture
(Catena, 2019-03-01) [Nota]
Bermudagrass (Cynodon spp.) is widely recognized by its ability to respond positively to nitrogen (N) fertilization. Nitrogen often promotes shoot and root growth and, consequently, increase carbon (C) inputs into the soil ...
Curva de crescimento e marcha de absorção de macronutrientes em três cultivares de amoreira (Morus alba L)
(Revista de La Ciência Del Suelo Y Nutricion Vegetal, 2009-01-01) [Artigo]
To evaluate the growth and pattern of nutrient absorption (N, P, K, Ca, Mg and S amongst others) in three berry cultivars (treatments), four plants by treatment in different phonological stages were harvested. The experiment ...

Nitrogênio em cobertura e molibdênio foliar no feijoeiro de inverno
(Acta Scientiarum: Agronomy, 2010-03-01) [Artigo]
Mesmo sendo uma planta capaz de realizar a fixação de nitrogênio em simbiose com o Rhizobium, várias pesquisas mostram que a fixação não supre as necessidades do feijoeiro em relação a esse nutriente. A aplicação de ...
Effects of long-term no-tillage systems with different succession cropping strategies on the variation of soil CO2 emission
(Science of the Total Environment, 2019-10-10) [Artigo]
The optimization of conservationist production systems, whose goal is to increase carbon stocks and reduce greenhouse gas emissions, is considered one of the greatest challenges faced by agriculture nowadays. Therefore, ...
