Peanuts are an excellent agricultural alternative for farmers from Chaco Central because of its nutritional value and adaptability to semiarid climates. The research was conducted between January and June 2013, at the Chacra Experimental Isla Poí from the Servicio Agropecuario of the Cooperative Society Chortitzer Ltda., district of Loma Plata (22° 29' 38.7 '' South and 59° 43'53.2'' West), Department of Boquerón and on a farm producer from the district of Teniente Irala Fernández (22° 58' 20,9 '' South and 59° 31' 42,8 '' West), Department of Presidente Hayes, Paraguay, in order to evaluate the agronomic performance of five varieties of semi erect peanut. The experimental design was randomized complete blocks with factorial arrangement 2 x 5, with four replicates. The factors were constituted by the two localities (Isla Poí and Teniente Irala Fernández) and the five varieties (Pytá, Negrito, Moroti, Rosado and Tatú IAC), considering the variables yield with shell and without shell, percentage of shell and mass of thousand grains. The data obtained were subjected to analysis of variance and the means compared by Tukey test at 5% probability of error. There was no interaction between factors for any of the characteristics studied. Significance between locations for the variables evaluated was found, except for the percentage of shell. In Teniente Irala Fernandez grain yield and mass of a thousand grain was 25.74% and 31.11%, higher than in Isla Poí. Among varieties there were differences in the mass of one thousand grains where Pytá (503.62 g) was superior to Negrito (423.50 g). Grain yield ranged from 1.39 t ha-1(Negrito) and 1.79 t ha-1 (Pytá), indicating that the cultivation of peanuts is an agronomical alternative for the conditions of Paraguayan Central Chaco.
