“…According to DoVale et al (2012), genitors contribute in a differentiated way to the transmission of alleles that control efficiency in the use of nitrogen. Sousa et al (2018) verified that AG 1051 was more effective in using nitrogen to produce green ears as compared to Cruzeta and Truck.…”

Maize plays an important role in the economy and the social and cultural development of several regions in Brazil. However, its productivity is considered low, since the management of nitrogen fertilization and the selection of efficient cultivars in using nitrogen are the main factors responsible for the low productivity of this crop. This study had the purpose to evaluate the efficiency of nitrogen usage in maize cultivars for the production of grains. The experiment was conducted at the vegetable garden at Universidade Federal Rural do Semi-Árido, in the municipality of Mossoró -Rio Grande do Norte state, Brazil. Treatments consisted in the combination of two nitrogen doses (0 and 90 kg N ha -1 ) and three maize cultivars (Cruzeta, Truck and AG 1051). A randomized complete block experimental design was used, in a 2 x 3 factorial arrangement, with five replications. The most productive performance was observed when the evaluated cultivars were fertilized with nitrogen. Based on the values from nutritional indices, cultivar AG 1051 was more efficient in using nitrogen to produce grains.
