Speech Title: Agronomic factors of corn (Zea mays L.) produced under water stress conditions and fertilized with biofertilizer in the semi-arid region of Paraíba, Brazil.

Abstract: In semiarid areas producing corn in the state of Paraiba (Brazil), despite the social and economic importance of this culture associated with some types of stress mainly in semiarid regions, this is a scientific study, with rigorous methodological methods, which emphasizes several interactions between soil-water-plant and their specific implications between causes and effects on the initial production of corn plants in semiarid regions. This study aims to analyze the vegetative growth and productive parameters of corn (Poaceae) fertigated with bovine biofertilizer under irrigation levels. It’s a very recurrent agricultural practice in world and in Brazil, working with low quality waters and use of ecological organic inputs, as the bovine biofertilizer made in semiarid regions, as it involves a social, cultural and environmental issue, as well as emphasizing the salinization and sodification of Brazil's agricultural lands, and even in semiarid regions, of county to Catole do Rocha-PB.

Keywords: Corn; Water losses; Biofertilization; Variety Caatingueiro.
