Agronomic characteristics of forage sorghum genotypes
Keywords
Abstract
The objective of this study was to evaluate the agronomic performance of 19 sorghum genotypes in three Brazilian cities. The sorghum genotypes evaluated were planted in three Brazilian municipalities: Goiânia, Nova Porteirinha and Sete Lagoas. A total of 19 sorghum genotypes were evaluated. The hybrids tested were: 15F27012, 15F27006, 15F27013, 14F20019, 15F26006, 14F21021, 14F20005, 13F26006, 15F26005, 15F27005, 15F30006, 15F30005, 15F270011, 15F26019, 13F26005, 13F03034, VOLUMAX, BRS658, BRS655. The genotypes planted in the three municipalities were evaluated for their agronomic characteristics. When evaluating the genotypes in each cultivation site, there was a variation among them (p<0.05) regarding the number of days to flowering in all municipalities evaluated. The genotype 15F27005 stood out among all the municipalities, obtaining its averages in lower flowering days than the other genotypes tested. Among the municipalities, there was variation in the value of plant height for most of the genotypes studied (p>0.05). The genotypes 15F30006, 15F30005 and 13F0334 showed higher mean heights in the three municipalities evaluated and both were influenced by the place of cultivation. The yields of MV and DM were influenced by the cultivation site for most of the genotypes evaluated (p<0.05). As for PMV, the genotype 15F3005 stood out among the others, because, despite having production influenced by the place of cultivation, it obtained a higher average in all the municipalities evaluated. Dry matter production between genotypes and municipality ranged from 7.0 t/ha-1 to 14.9 t ha-1 for genotypes 15F26006 and 15F30005, in Sete Lagoas and Goiânia, respectively. The genotypes 15F30006, 15F30005, 15F270011, VOLUMAX, BRS658, BRS655 stood out among the others, as they presented higher averages of dry matter production in at least two of the municipalities evaluated, demonstrating their adaptation to different cultivation sites.
