In the greater part of the crops, the density of sowing represents one of the elements which directly fall into production, mainly of basic seeds and specially corn. This job was made between 1984 and 1986 whose main objective was to evaluate commercial varieties and hybrids of corn to a different crops densities, for a mechanical system of corn production. The results allow us to indicate the feasibility of corn production in mechanical crops into densities of 62,500 plants by hectare (0.80 x 0.20 cm) with the suggested varieties and hybrids to Chiriqui on the hindermost crop. With this density we got outputs of 5265, 3421 and 5543 kg/ha, respectively, being the most stable density through the years of the evaluation. The commercial hybrids X-304C, X-306B and X-3214 got the greatest outputs from all the years with 5489, 4477 and 4763 kg/ha, respectively. Between the national varieties Across 7728 and Tocumen 7428 got outputs of 4585 and 4334 kg/ha, respectively.
