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. 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

4. 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

5. 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

6. 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

7. 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

8. Aproveitamento por soqueira de cana-de-acucar de final de safra no nitrogenio de aquamonia 15N e ureia 15N aplicado ao solo em complemento a vinhaca.
O aproveitamento por soqueira de cana-de-acucar de final de safra do nitrogenio da aquamonia e da ureia ao solo foi avaliado pela tecnica isotopica cm 15N. O experimento foi conduzido em area comercial de cana da variedade SP 70-1143, primeira soca, no Estado de Sao Paulo. Cada tratamento (aquamonia e ureia) contou com 19 linhas de 10m de comprimento, com es

10. Fluxos de emergência, épocas de aplicação de herbicidas e sistemas de manejo de plantas daninhas em cana-de-açúcar / Emergence fluxes, herbicide application timings and weed management systems in sugarcane
The knowledge of the effects of the population dynamics and establishment velocity of weeds on the efficacy of weed management in the sugarcane crop is fundamental for the development of a rational plan of integrated weed management in the crop. Therefore, the objectives of the present research were: (i) to quantify the monthly fluxes of weed emergence year

11. Sewage sludge application in cane-plant as nitrogen and phosphorus source and its environmental effects / Aplicação de lodo de esgoto em cana-planta como fonte de nitrogênio e fósforo e seu impacto ambiental
The potential agricultural use of the sewage sludge is due to their organic matter and nutrients contents, mainly nitrogen and phosphorus, the most important constituint. However, there is a lack of research to adequate the nitrogen and phosphate fertilizer doses to be applied in agricultural fields treated with this residue. Despite the evident benefits of

12. 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
