1. Estimated productivity of sugarcane through the Agro-Ecological Zone method
ABSTRACT The estimate of the potential sugarcane productivity through agroclimatic models aids in the agricultural planning of the crops and the quantification of the yield for a given region. For these estimated values to be considered robust there is a need for validating the performance of such models in different areas and agricultural varieties. Hence,

2. Sugarcane root distribution and growth as affected by genotype and crop cycle
ABSTRACT Sugarcane (Saccharum L. spp. hybrids) is a globally important crop. While roots contribute to its net primary production, knowledge of sugarcane root growth is incomplete and limited in scope. The objective of this study was to determine cumulative root density (LA), root distribution, effective rooting depth (ERD), and root growth rate for four sug

3. Sugarcane inoculated with endophytic diazotrophic bacteria: effects on yield, biological nitrogen fixation and industrial characteristics
Abstract: The growing need for the use of clean energy has led society to seek alternatives to fossil fuels in order to less pollute the environment. Sugarcane has been known to produce enough biomass and to have associative microorganisms, such as plant growth-promoting bacteria (PGPB), which have the potential to improve the yield of crops. The objective

4. 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

5. Sugarcane Root Development and Yield under Different Soil Tillage Practices
ABSTRACT New strategies for sugarcane production have been very important since the incorporation of ethanol in the Brazilian energy mix in the early 1970s. Prior to planting sugarcane, the soil is prepared, and this process can affect root development and, consequently, sugarcane production. This study was conducted in an area of sugarcane crop renewal in t

6. Soil organic matter fractions affected by N-fertilizer in a green cane management in Brazilian Coastal Tableland
ABSTRACT The recent approach of eliminating the use of fire for sugarcane harvesting (green cane) resulted in managing the crop on a trash-blanketed soil, which changed the content and dynamic of carbon and the nitrogen requirement. These alterations are relevant due to economic and environmental aspects of sugarcane production systems. This study aimed to e

7. 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

8. Hydrophysical Quality of an Oxisol and Sugarcane Yield in Chisel Plow-Based Sugarcane Ratoon Management
ABSTRACT Mechanical harvesting has increasingly been used in sugarcane production units, and it has often resulted in reduced structural quality of the soil due to soil compaction caused by machine traffic. Thus, sugarcane ratoon crops have often been chiseled to overcome such a problem. The aim of the current study is to assess some physical properties of a

9. 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

10. Root growth and distribution in sugarcane cultivars fertigated by a subsurface drip system
Despite of the agronomic importance for water management, few studies of sugarcane roots have been performed under field conditions during the crop cycle. The aim of this study was to determine the cumulative root density (LA), root distribution on soil profile and the effective rooting depth (ERD) for three sugarcane cultivars using the minirhizotron method

11. 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

12. Produtividade da água em biomassa e energia para 24 variedades de cana-de-açucar / Water productivity in biomass and energy for 24 sugarcane varieties
The purpose of this study was to observe the response on biomass yield and energy (shoot) as well as the water productivity (WP) for 24 sugarcane varieties, subjected to full and deficit irrigation during stalk growth stage. Two experiments were established under greenhouse conditions on Biosystems Engineering Department, ESALQ/USP, Piracicaba, SP. The Exper
