Methods of supply of nitrogen to improve productivity in the culture of irrigated beans in savanna mato-grossense
(Univ Federal Mato Grosso, 2018-05-01)
Nitrogen is one of the elements most required by the bean crop and its supply to the plant can occur through nitrogen fertilization and through biological fixation. The objective of this study was to evaluate strategies ...
NON-SYMBIOTIC NITROGEN FIXATION, NET NITROGEN MINERALIZATION AND DENITRIFICATION IN EVERGREEN FORESTS OF CHILOÉ ISLAND, CHILE: A COMPARISON WITH OTHER TEMPERATE FORESTS
(Facultad de Ciencias Naturales y Oceanográficas, Universidad de Concepción, 2003)
Response of rice cultivars to nitrogen in upland conditions
Against the background of a growing world population, rice (Oryza sativa L.) consumption is expected to grow faster than its production. Therefore, an appropriate question would be: how to increase productivity in the ...
Dietary lysine deficiency increases the incorporation rate of nitrogen-free compounds in muscle of pacu (Piaractus mesopotamicus)
Isotopic experiments are conducted to evaluate turnover rates in fish tissue, especially as a function of nutrition. In 2007, Cerling et al. proposed an approach they named the reaction progress variable, which among other ...
INITIAL GROWTH IN MAIZE IN COMPLIANCE OF AZOSPIRILLUM BRASILENSE INOCULATION AND NITROGEN RATES
(Univ Federal Uberlandia, 2017-09-01)
Investigate the effects of the interaction between nitrogen fertilization and inoculation with diazotrophic bacteria becomes important, especially for maize, highly exacting in N. Thus, the aim of this study was to evaluate ...
Produção de tapetes de grama Santo Agostinho submetida a doses de nitrogênio
(Universidade Estadual de Londrina (UEL), 2012-01-01)
Nitrogen is the nutrient that provides the greatest turfgrass growth responses and the adequate nitrogen fertilization can provide sod formation in less time and firm to be handled after harvest. This study aimed to evaluate ...
Sulfur affects root growth and improves nitrogen recovery and internal efficiency in wheat
Wheat plants were cultivated in pots with the objective of evaluating the effect of two sulfur (S) rates (+S and −S) on (i) shoot growth, S and nitrogen (N) uptake and nitrogen use efficiency (NUE) and (ii) root growth and ...
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 ...
