Abstract

This study had as objective to quantify achenes, leaves, stem and capitulum production and participation, as well as green and dry matter production of two sunflower hybrids for silage production. Two sunflower hybrids, Helio 251 (H251) and Helio 360 (H360), were used and implanted under oat stubble. The counting of twelve points with five linear meters/hectare of each hybrid was carried out to evaluate hybrid production and five samples were taken to evaluate plant composition. A complete randomized experimental design was used and the averages were analyzed by Tukey test. H251 hybrid presented higher plants per linear meter and per hectare (3.99 vs. 3.12 plants/m; 49,953.95 vs. 38,342.10 plants/ha, for H251 and H360, respectively). H360 capitulum were heavier than the ones from H251, when expressed in green (303.79 g/plant) or dry (56.88 g/plant) matter basis, consequently, it showed heavier achenes (151.09 and 100.12 g/plant, respectively, for green and dry matter). H360 presented higher stem weight, when expressed in green (120.95 vs. 61.27 g/plant) or dry (48.58 vs. 29.01 g/plant) matter basis. The higher weights of capitulum, achene and stem presented by H360 resulted in heavier plants and superiority on dry matter production per hectare.
