MORPHOGENESIS, STRUCTURAL CHARACTERISTICS AND FORAGE ACCUMULATION OF Megathyrsus maximus BRS ZURI SUBJECTED TO NITROGEN FERTILIZATION
(Inst Zootecnia, 2020-01-01)
Nitrogen fertilization permits to increase the carrying capacity of pastures; however, the use of high doses can have negative effects on the growth of forage grasses. Therefore, the aim of this study was to evaluate the ...
Foliage area and crown nitrogen turnover in temperate rain forest juvenile trees of differing

Fertilisation residues alter leaf scleromorphy in an evergreen savannah shrub (Maprounea brasiliensis, Euphorbiaceae)
(2013-07-11)
In the present study, we examined how residues of nitrogen (N), phosphorus (P) and calcium (Ca) fertilisers affect leaf anatomical traits in Maprounea brasiliensis (Euphorbiaceae), a typical and dominant cerrado (Brazilian ...
Características morfogênicas e estruturais de híbridos de sorgo submetidos a adubação nitrogenada
(2012-10-01)
The effect of two topdressing nitrogen doses was evaluated on the morphogenetic and structural characteristics of sorghum hybrids (Sorghum bicolor (L.) Moench) BRS 801 and 0734006, cultivated in vases in open-air conditions. ...
Morphogenetic and tillering dynamics in Tanzania grass fertilized and non-fertilized with nitrogen according to season
(Sociedade Brasileira de Zootecnia, 2012-03-01)
The objectives of this study were to evaluate morphogenetic characteristics and tillering dynamics in Tanzania grass fertilized and non-fertilized with nitrogen, under intermittent grazing, in the spring and the summer. ...
Physiological responses of two tropical weeds to shade. II. Leaf gas exchange and nitrogen content.

Functional relationships between leaf hydraulics and leaf economics in response to nutrient addition in subtropical tree species
(Oxford Univ Press, 2013-11)
Leaves can be both a hydraulic bottleneck and a safety valve against hydraulic catastrophic dysfunctions, and thus changes in traits related to water movement in leaves and associated costs may be critical for the success ...
Criteria for topdressing nitrogen application to common bean using chlorophyll meter
(Empresa Brasil Pesq Agropec, 2017-07-01)
The objective of this work was to establish the diagnostic leaf and the nitrogen sufficiency index (NSI) values most appropriate to estimate N requirement by the 'Perola' common bean (Phaseolus vulgaris), based on chlorophyll ...
