In this study, the objective was to perform a brief review on morphological characteristics, genetic improvement and planting density of sorghum (Sorghum bicolor L.) and corn (Zea mays L.) crops. The search for the literature included in the study was conducted by means of an electronic search in the Google Scholar and Scientific Electronic Library Online (SciELO) databases, on the web and on the Empresa Brasileira de Pesquisa Agropecuária - EMBRAPA websites. As inclusion criteria, we considered bibliographies dealing with topics related to morphology, genetics and planting densities of corn and sorghum. The exclusion criteria for the bibliographies were: studies outside the study's objective and that did not contemplate the established period and language of the research. In general, corn and sorghum are grasses that directly contribute to the production chain and agribusiness due to their nutritional importance in animal production systems. Their botanical, morphological and phenological characteristics allow these crops to show good productivity and adaptability in different regions of Brazil (South, Central and Northeast). The ability of corn and sorghum to adapt to different edaphoclimatic conditions depends on the genetic potential of the seed and the planting system used, as well as the competence of the genotype type to withstand high population densities to some extent. We suggest conducting studies to individually evaluate the morphological and phenological attributes of different varieties of corn and sorghum and their adaptation and production abilities at different planting densities.
