“…Just as for cane-plant, the higher sugar yield was a result of the greater stalk productivity. Similar results were observed by Silva et al (2008), who observed no negative effects on the technical quality of ratoon stalks induced by applications of 5.32 and 10.65 t ha -1 sludge.…”

“…A higher yield was reported by Maule et al (2001) who obtained 154 t ha -1 , cultivating the same variety for 18 months in Red-Yellow Argisol (Hapludult). This is to be expected, because cane grown for 12 months is less productive than when grown for 18 months (Silva et al, 2008). Therefore, the yields of cane-plant grown for 12 months in this study can be considered excellent, particularly in the treatments with 7.2 and 10.8 t ha -1 sludge.…”

SUMMARYThe use of sewage sludge in Brazilian agriculture was regulated by the resolution no. 375 Conama, in 2006. However, there is a lack of research to adequate the mineral N and P fertilizer doses to be applied in agricultural fields treated with this residue. In a field experiment, the effects of application rates of sewage sludge and mineral N and P fertilizers on the productivity and technical characteristics of the cane-plant and first ratoon (residual effect) crops were evaluated. Four doses of sewage sludge (0, 3.6, 7.2 and 10.8 t ha -1 , dry base), of N (0, 30, 60 and 90 kg ha -1 ) and of P 2 O 5 (0, 60, 120 and 180 kg ha -1 ) were combined in a factorial and laid out on randomized block design, a with two replications. To evaluate the residual effect of the sludge, 120 kg ha -1 N and 140 kg ha -1 of K 2 O were applied in all plots. Sludge application at cane planting, with or without N and/or P fertilizer increased the stalk yield from 84 up to 118 t ha -1 , with no alteration in the sugarcane quality, compared with the application of NPK fertilizer alone, resulting in a stalk yield of 91 t ha -1 . The study of the response surface for stalk yield on lowfertility soil was the basis for a recommendation of mineral N and P fertilizer doses for sugarcane implantation as related to sewage sludge application rates. It was also concluded that a sludge application of 10.8 t ha -1 , which is the sludge dose established based on the N criterion according to the resolution Conama n o 375, could a) reduce the use of mineral N by 100 % and of P 2 O 5 by 30 %, with increments of 22 % in stalk yield, as a direct effect of sludge application to cane plant crop, and b) increase the stalk yield in the second harvest (first ratoon) by up (1)

ResumoO uso de bioestimulantes na cultura da cana-de-açúcar (Saccharum officinarum L.) é uma prática de manejo que potencialmente pode incrementar sua produtividade e o seu rendimento industrial, favorecendo o bom desempenho dos processos vitais da planta, permitindo obter melhores e maiores colheitas, mesmo sob condições ambientais adversas. Para o efeito desejado com o uso de bioestimulantes específicos é importante conhecer o processo regulado pelo hormônio ou grupo de hormônios, a dose necessária para manipular o processo, bem como o órgão da planta onde ocorrerão as reações biológicas. Por sua composição de múltiplos hormônios em baixas concentrações, bem como pelas pequenas doses recomendadas, a aplicação isolada de um bioestimulante dificilmente poderá regular ou manipular

RESUMENLas técnicas tradicionales de preparación de suelo han limitado la productividad de algunos cultivos. Facilitar el desarrollo de la planta mejorando mejorando las condiciones agrícolas, sin que ello afecte al ambiente, ha motivado la creación de nuevas tecnologías de producción en zonas rurales. Una de las tecnologías probadas es la preparación profunda de suelo, que promueve el desarrollo del sistema radicular de las plantas debido a una mejor aireación y baja compactación, lo que facilita la absorción de agua y nutrientes, ayudando a su desarrollo y favoreciendo una mayor productividad. Este trabajo tiene por objetivo evaluar el desarrollo morfológico de la planta en dos localidades de producción de cultivo de caña de azúcar, una de ellas manejada con maquinaria de preparación profunda de suelo en canteros y la otra, por los métodos de preparación convencional. El experimento fue realizado en Lençóis Paulista, São Paulo, en la empresa PHD, perteneciente al Grupo Zilor. Las variables analizadas fueron: macollamiento, diámetro del tallo, altura de planta, y su productividad. El macollamiento presentó mayores valores en la Preparación Profunda de Suelo en Canteros (PPC) en comparación con la Preparación Convencional (PC) a los 120 días de la siembra de caña de azúcar y después del corte y la altura de la planta únicamente presentó mayores valores para el PPC a los 390 días después de la siembra de caña de azúcar. Un ciclo (o corte) no fue suficiente para mostrar una diferencia significativa en la productividad de caña de azúcar entre los tratamientos analizados (Preparación Profunda de Suelo en Canteros y Preparación Convencional).Palabras claves: preparación de suelos, labranza, subsolado, azada rotativa, Saccharum spp. ABSTRACT IntroducciónDiversos factores pueden interferir en la productividad y en la calidad agronómica de la caña de azúcar que represente una integración de las diferentes condiciones del proceso de producción del cultivo (Gilbert et al., 2006). Para la siembra de caña y nivelación del relieve del terreno los productores utilizan equipos de preparación intensiva y profunda del suelo que
