Title A name given to the resource Desempenho do arroz irrigado em resposta à utilização de cianobactérias fixadoras de nitrogênio = Performance of paddy rice in response to the use of nitrogen-fixing cyanobacteria Creator An entity primarily responsible for making the resource Thomas Newton Martin, Edgardo Oscar Brenzoni, Edinalvo Rabaioli Camargo, Luis Antonio de Avila, Enio Marchesan, Fernando Machado dos Santos Description An account of the resource O objetivo do presente estudo foi avaliar a utilização de inóculos decianobactérias fixadoras de nitrogênio como alternativa à adubação química de nitrogênio na cultura do arroz irrigado. Para tanto, foram conduzidos quatro experimentos, nos anos agrícolas de 1999/00 a 2002/03, avaliando os tratamentos: testemunha sem aplicação de N em cobertura; 20 kg ha-1 de N aplicado em cobertura; 40 kg ha-1 de N aplicado em cobertura; 90 kg ha-1 de N aplicado em cobertura; 50 g ha-1 de Rizogram®; 100 g ha-1 de Rizogram®. Verificou-se interação dos tratamentos com os anos avaliados, o que pode ter ocultado o desempenho destes. Além disso, verificou-se que, para a variável “número de grãos por panícula”, a utilização de cianobactérias nas duas dosagens estudadas (50 e 100 g ha-1) produziu resultados semelhantes à adubação nitrogenada (90 kg ha-1), com potencialredução do número porcentual de espiguetas estéreis. Os tratamentos não afetaram o rendimento de grãos do arroz irrigado, devido às variações ambientais dos anos avaliados.A four-year experiment irrigated rice was carried out in order to evaluate the performance of Nostoc sp. and Tolypothrix sp. nitrogen-fixing cyanobacteria strains (Rizogram™), as an alternative to chemical nitrogen fertilization in irrigated rice. The treatments evaluated in the experiments included: control without top dressing Napplication; top dressing application of 20, 40 and 90 kg ha-1; 50 g ha-1 of Rizogram™, and 100 g ha-1 of Rizogram™. It was verified interaction between the years of the study and the treatments, which may have affected the performance of these treatments. Moreover, it was observed that, for the number of grains per panicle, the use of cyanobacteria in two studied rates (50 e 100 g ha-1) produced the same results as the nitrogen fertilization (90 kg ha-1), showing potential reduction of sterile spikelets. However, the treatments did not affected rice grain yield.
