The primary objective of this research was to evaluate the performance of seven maize genotypes function to five levels of nitrogen, in the spring-summer cycle 2014, for evaluating: leaf area index, biomass, yield and harvest index under a design randomized complete block factorial arrangement, low irrigation conditions on the premises Universidad Tecnologica de Tehuacán in Tehuacán Puebla México which is located at 18° 24'51'' north latitude, 97° 20'00'' west longitude and 1409 meters above sea levela climate Bs1(w’) eg, corresponds to a dry climate with annual mean temperature over 18°C and less than 27 °C, precipitation higher than 400mm and smaller than 600mm rain fall stations. Results indicate that the level of 180kgha-1 of N, It presents the maximum values of IAF, biomass and yield, whereas the cultivating Tehuacán, it reached maximum production of biomass and yield, nitrogen x cultivar interaction indicated that the implementationof180kgNha-1in the cultivar Altepexi. Sample the maximum grain yield and this geno type that best suits to the environmental conditions in the study area.
