1. Decision-making on the optimum timing for nitrogen fertilization on sugarcane ratoon
ABSTRACT: Low efficiency of nitrogen from fertilizers is a major concern worldwide, threatening the sustainability of sugarcane production. The N use efficiency (NUE) by sugarcane can be improved by adopting better fertilizing management practices, reducing environmental impacts. This work evaluated the effects of varying N rates and time of application on s

2. Agronomic performance of green cane fertilized with ammonium sulfate in a coastal tableland soil
ABSTRACT The recent approach of eliminating the usage of fire for sugarcane harvesting resulted in managing the crop on a trashblanketed soil, to which a proper recommendation of N fertilization is lacking, a problem that remains in the coastal tablelands of the Espírito Santo State, Brazil. This study aimed at evaluating the effect of increasing N rates on

3. Residual recovery and yield performance of nitrogen fertilizer applied at sugarcane planting
ABSTRACTThe low effectiveness of nitrogen fertilizer (N) is a substantial concern that threatens global sugarcane production. The aim of the research reported in this paper was to assess the residual effect of N-fertilizer applied at sugarcane planting over four crop seasons in relation to sugarcane crop yield. Toward this end three field experiments were es

4. Interação entre os estresses de nitrogênio e disponibilidade hídrica no fracionamento isotópico de 13C e na produtividade em soqueira de cana-de-açúcar / Interaction between nitrogen and water availability over isotopic discrimination of 13C and ratoon sugarcane production
The sugarcane crop has an important contribution in sub tropical and tropical regions around the world, which Brazil the major producer of sugarcane crop, sugar and ethanol. However, the sugarcane yield is still very low in many regions of this country, mainly due to water stress and nitrogen supply. Understand the loss sugarcane production related with wate

5. Cana-de-acucar cultivada em solo adubado com lodo de esgoto.
A pesquisa objetivou avaliar o uso de lodo de esgoto (Le) na adubacao de soqueira (2.corte) de cana-de-acucar (Saccharum spp, var.RB72-454). A plicou-se Le ao solo, localizando-o no fundo de um sulco com 15 cm de profundidade e distando 40 cm da linha da cana. Avaliaram-se os efeitos das doses do Le (0,15 e 30 t.ha) nas produtividades de biomassa e de acucar

6. Agronomic efficiency of the sugarcane ratoon fertilization with ammonium chloride / Eficiência agronômica da adubação de soqueira de cana-de-açúcar com cloreto de amônio
The greatest difficulty of incorporation into the soil of nitrogen fertilizer is worrying in the system of "green cane" (sugar cane harvested without burning), and once that urea is the nitrogen source most used, we can incur risks of loss by volatilization of NH3. Accordingly, an experiment was conducted in the field (Distrofic Red Oxisol clayed) to evaluat

7. Eficiência agronômica das adubações nitrogenadas de plantio e após o primeiro corte avaliada na primeira soca da cana-de-açúcar / Agronomic efficiency of nitrogen fertilization at planting and after the first harvest, evaluated during the first sugarcane ratoon cultivation
Renewable energy sources will gradually replace non-renewable sources due to economic sustainability reasons and to the rational use of natural resources. Consequently, this study aimed to investigate sugarcane nitrogen fertilization in detail, which may help the country to become a world model in the production and use of renewable biofuels. The current kno

8. Desenvolvimento de raízes e produtividade de cana-de-açúcar relacionados à adubação nitrogenada / Root growth and sugarcane productivity related to nitrogen fertilization
Studies of nitrogen fertilization in sugarcane are usually restricted to evaluations of the effects on growth and productivity of the shoots. There are evidences that nitrogen fertilization favors the growth of roots, the absorption of nutrients and sugarcane productivity. This work was designed to evaluate root development and sugarcane productivity (SP81 3
