The occurrence of grain losses after the harvest have a significant importance for the world food supply.The breakdown exists in the mass of grains or seeds stored and relates to weight loss over the storage period.This loss occurs due to chemical oxidation reactions during the respiratory process.In this context, the aim of this research was to evaluate the effect of drying temperatures of corn grains in the storage period in two types of packages under uncontrolled environmental conditions and the use of different methods to determine weight loss and technical breaking of corn on the cob.The Dow Agroscience variety with initial moisture of 26% was used.Three temperature combinations of drying air were used: 40-45 ° C; 50-55 °C and 70-75 °C and the control was sun drying.Some methods were used to determine direct or indirect weight loss by the methods proposed by Harris and Lindblad (1978), by Compton et al. (1998), by Bern et al. (2002) and by White et al. (1982).The experiment was set up in a randomized complete design, with four treatments, consisting of a storage environment and five sampling periods for evaluations, in a factorial arrangement, with three replications per treatment and the statistical data analysis was analyzed by the SAEG 5.0.There were differences of weight losses in the different packages and in two methods of determination of the losses in paper and plastic packages there was no significance.
