Influence of Urea and Ammonium Sulfate on Soil Acidity Indices in Lowland Rice Production
(TAYLOR & FRANCIS INC, 2010)
Urea and ammonium sulfate are principal nitrogen (N) sources for crop production. Two field experiments were conducted during three consecutive years to evaluate influence of urea and ammonium sulfate application on grain ...
Sources, Rates and Time of Nitrogen Application on Maize Crops under No-Tillage System
(Taylor & Francis Inc, 2016-01-01)
Quantitatively, nitrogen (N) is the foremost nutrient for maize crops (Zea mays L.), but the N source to increase the grain productivity still needs more investigation. Thus, the aim of this experiment was to study sources, ...
Doses and sources of nitrogen fertilizer and their effects on soil chemical properties and forage yield of Brachiaria brizantha cv. Xaraes
(Universidade Estadual de Londrina (UEL), 2012-01-01)
Forage plants, particularly the Brachiaria genus, are the main source of nutrients for cattle and are at times the only feed offered. The concentration of elements in the plant is related to the soil, fertilization, climate, ...
Biofilm production by Aureobasidium pullulans improves biocontrol against sour rot in citrus
The biocontrol efficiency of Aureobasidium pullulans strain ACBL-77 against Geotrichum citri-aurantii, causal agent of sour rot in citrus, and their interactions were evaluated. For this, were evaluated the incorporation ...
Purification and characterization of xylanases from Aspergillus giganteus
A strain of Aspergillus giganteus cultivated in a medium with xylan produced two xylanases (xylanase I and II) which were purified to homogeneity. Their molar mass, estimated by SDS-PAGE, were 21 and 24 kDa, respectively. ...
Influence of urea and ammonium sulfate on soil acidity indices in lowland rice production.
(Communications in Soil Science and Plant Analysis, New York, v. 41, n. 13, p. 1565-1575, Jul. 2010., 2011)
Importance of the nitrogen source in the grass species Brachiaria brizantha responses to sulfur limitation.
(Plant and Soil, The Hague, v. 373, n. 1/2, p. 201-216, 2013., 2013)
Doses, fontes e épocas de aplicação de nitrogênio em arroz de terras altas cultivado em sistema de semeadura direta
(Univ Fed Rural Semi-arido-ufersa, 2013-01-01)
The crop demand by nitrogen varies from one crop to other as well as the amount and application time, and this nutrient can be lost by leaching, volatilization and erosion. The objective of this study was to evaluate doses, ...
