SUMMARY:

The objective of this research was to evaluate the performance and production characteristics aimed at silage production, of seeds distributed by the Government of the state of Rio Grande do Norte for family farming, Milho BRS Potiguar (Treatment 1), Milho BRS Cruzeta (Treatment 2), Sorghum BRS Ponta Negra (Treatment 3) and the possibility of recommending Millet BRS 1501 (Treatment 4) under drip and fertilization supervision. Options for using seeds for silage were specified, measuring characteristics of green mass production, dry mass production, leaf mass production, bunch mass production, leaf:stalk ratio; green and ensiled chemical composition; quantification of losses in the ensiling process, the data were subjected to the Tukey test at 5% significance. An estimate of the production costs of each tested variety was carried out, indicating the total income per hectare, net income and rates of return. Bringing another option for using varieties distributed to family producers in Rio Grande do Norte or similar regions, it can also be one of the decision-making measures, given the comparisons between the corn silages Potiguar, Cruzeta, Sorgo Ponta Negra and Milheto 1501. Allow professionals to choose the most appropriate to the individual needs of each farm, in a more precise and objective way. Corn varieties can be used as a forage option to replace sorghum in the program, as there is no difference in the production of green mass between treatments, in addition to presenting superior chemical composition of the silage. Millet can be a lower investment option, but less productive. Under irrigated conditions, it is more financially advantageous to produce corn than sorghum.
