Phenotyping open-pollinated maize varieties for environments with low nitrogen availability
(2018-08-24)
The high nitrogen nutrient requirement of maize is a major production constraint in areas that have a low availability of soil nitrogen. A 2-year field experiment was conducted to characterize open-pollinated varieties of ...
YIELD OF FERTIGATED BELL PEPPER UNDER DIFFERENT SOIL WATER TENSIONS AND NITROGEN FERTILIZATION
(Univ Fed Rural Semi-arido-ufersa, 2020-01-01)
Considering the lack of technical information on the water depth and nitrogen fertilization via fertigation in protected cultivation for bell pepper production in northern Brazil, this paper aimed to study the soil water ...
Physiological performances of two populations of Compsopogon caeruleus (Rhodophyta) to inorganic nitrogen and phosphorus impoverishment
(2014)
Studies on the effects of inorganic nutrients manipulation (specially nitrogen and phosphorus) in freshwater macroalgae are scarce. Physiological responses (growth, photosynthesis, and pigment contents) to nitrogen and ...
The relationship between leaf nitrogen, nitrogen metabolites and herbivory in two species of Nyctaginaceae from the Brazilian Cerrado
(PERGAMON-ELSEVIER SCIENCE LTDOXFORD, 2012)
Guapira graciliflora and Neea theifera are taxonomically related species of the tribe Pisoneae. Both species are found in the same environment, the Brazilian Cerrado, and therefore, are subjected to similar selective ...
Cereal yield in Mediterranean-type environments: challenging the paradigms on terminal drought, the adaptability of barley vs wheat and the role of nitrogen fertilization
(Academic Press, 2015)
Under Mediterranean environments most of the cereals are produced under rainfed conditions, exposing crops to different severity of water stress due to scarce and variable rainfall. In this chapter, we revise three elements ...
