The Saracura maize BRS – 4154 was introduced as an alternative for swamp land areas subjected to temporary flooding. Evidences are usually obtained with CaCl2 presence in flooding germination buffer which increases the tolerance of Saracura. However, such experiments were carried out in controlled conditions, during germination and initial development phases of seedlings. There have been no papers, so far, showing the influence of calcium during the maize development cultivated at field conditions. Therefore, the objective of this research was to evaluate, during the vegetative and reproductive development of Saracura maize, the effect of different levels, sources and mode of calcium application in flooding conditions.
