The analysis of the agronomic characteristics of different genetic materials indicates the one
that has the highest productivity. This research aimed to evaluate the agroeconomic characteristics of corn
hybrids for silage in the Alagoas semiarid region. The experiment took place in the experimental field of the
Federal Institute of Alagoas, Campus Piranhas, located in the municipality of Piranhas in the State of Alagoas,
a semiarid portion of Northeast Brazil, in rainfed conditions, under a block design randomized, with eight
treatments and four replications. The treatments were eight corn hybrids (K9555 VIP 3, R9080 PRO 2, K9822
VIP 3, K9606 VIP 3, K9510 Conventional, K8774 PRO 3, RB9006 PRO 2 and 2B587 PW). At the pasty/
farinaceous grain stage, the following characteristics were evaluated: green and dry mass of leaves, stem, cob,
tassel, and total (g plant-1); green and dry mass productivity (t ha-1) and percentage of dry mass (%). Gross
income, net income, rate of return, and profitability index were determined for economic variables. The highest
average value for dry mass productivity occurred in the hybrid R9080 PRO 2 with 11.04 t ha-1, not differing
from the others, except for 2B587 PW with 5.62 t ha-1. The 2B587 PW is the least recommended for silage, and
the K9555 VIP 3 and K9510 Conventional are the most recommended. The total production cost averaged R$
5,863.51 ha-1. Inputs had the highest average cost (53.62%), followed by harvesting operations (30.28%). All
hybrids presented equal economic results, but the 2B587 PW hybrid is the least recommended because it has
the same production costs but undesirable agronomic characteristics.
