Nitrogen Application in Irrigated Rice Grown in Mediterranean Conditions: Effects on Grain Yield, Dry Matter Production, Nitrogen Uptake, and Nitrogen Use Efficiency
(TAYLOR & FRANCIS INC, 2009)
Field experiments were conducted in the major rice growing area of Chile to evaluate the effects of nitrogen (N) fertilization and site on grain yield and some yield components, dry matter production, N uptake, and N use ...
Atmospheric concentrations and dry deposition of reactive nitrogen in the state of São Paulo, Brazil
(2020-06-01)
Estimates of nitrogen deposition play a key role in better understanding the human impacts on the nitrogen biogeochemical cycle. This paper examines the concentration of reactive nitrogen (Nr) in the atmosphere and the ...
Effect of nitrogen supply on growth and photosynthesis of sunflower plants grown in the greenhouse
(Elsevier B.V., 2004-05-01)
The effects of nitrogen availability on growth and photosynthesis were followed in plants of sunflower (Helianthus annuus L., var. CATISSOL-01) grown in the greenhouse under natural photoperiod. The sunflower plants were ...
