Resumo: The aim of this study was to compare the use of water and nitrogen on ratoon sugarcane during irrigated and rain-fed conditions, and to assess the production potential of stalks and sugar with different rates of N-fertilizer on the subsurface drip-irrigated management. The experimental design was a randomized block with four replications for each experiment and treatments: (T1) irrigated, 0kg N ha-1; (T2) irrigated, 70kg N ha-1; (T3) irrigated, 140kg N ha-1; (T4) irrigated, 210kg N ha-1; (T5) not irrigated, 0kg N ha-1, and (T6) not irrigated, 140kg N ha-1. Biometric, technological, dry matter and yield variables were analyzed among the treatments. The irrigation system together with the application of N-fertilizer at 140kg ha-1 presented significant differences in dry matter accumulation of shoots, and for the production of stalks and sugar, respectively 94, 105 and 106%, higher when compared to the not irrigated, without N-fertilizer (T5). There was a positive and synergistic effect of irrigation with N-fertilizer on the productivity of stalks and sugar. Ratoon sugarcane irrigated with subsurface dripping had the highest yield (22Mg ha-1 of sugar) with the dosage of 140kg ha-1 N.

O delineamento experimental utilizado foi o de blocos ao acaso, com seis tratamentos e quatro repetições, sendo os tratamentos: (T1) irrigado, 0 kg N ha-1; (T2) irrigado, 70 kg N ha-1; (T3) irrigado, 140 kg N ha-1; (T4) irrigado, 210 kg N ha-1; (T5) manejo de sequeiro, 0 kg N ha-1; (T6) manejo de sequeiro, 140 kg N ha-1. Foram realizadas análises de variáveis biométricas, tecnológicas, de matéria seca e de produtividade entre os tratamentos. O sistema de irrigação, em conjunto com a aplicação de N-fertilizante na dose de 140 kg ha-1 (tratamento T3), gerou diferenças significativas para acúmulo de matéria seca da parte aérea e para produtividade de colmos e de açúcar, sendo, respectivamente, 94; 105 e 106% superiores ao tratamento de sequeiro, sem dose de N (T5). Verificou-se efeito positivo e sinérgico da irrigação com N-fertilizante na produtividade de colmos e de açúcar. A soqueira de cana-de-açúcar irrigada por gotejamento subsuperficial obteve a máxima produtividade (22 Mg ha-1 de açúcar) com a dose de 140 kg ha-1 de N.Universidade Sagrado CoraçãoAPTAUNESP FCACTBEUNESP FCAAssociação Brasileira de Engenharia Agrícola (SBEA)Universidade Sagrado CoraçãoAgência Paulista de Tecnologia dos Agronegócios (APTA)Universidade Estadual Paulista (Unesp)CTBEUribe, Raúl A.
