Abstract

PINHO, Ricardo Martins Araujo et al. Evaluation of genotypes of pearl millet for silage in semiarid. Rev. bras. saúde prod. anim. [online]. 2013, vol.14, n.3, pp.426-436. ISSN 1519-9940.  https://doi.org/10.1590/S1519-99402013000300003.

The objective of this research was to evaluate the forage yield, agronomic characteristics and morphometric plants and losses, fermentation and chemical composition of silages of pearl millet genotypes. To evaluate the agronomic and morphometric characteristics of genotypes it was used the randomized blocks experimental design with five replicates. In the phase of silos evaluation the design has become completely randomized design with four replications. Cultivars tested were Sauna B, CMS 01, ADR 500, BRS 1501 and CMS 03. There was no difference for PFF, DMP and DM. The pearl millet genotypes had a average PMV of 9073 kg/ha in the first cycle and 10.054kg/ha in the regrowth. As to the leaf and stem production there was not difference in both cuts. The concentration of AL ranged from 1.98 to 5.17% for genotypes B and CMS SAUNA 01, respectively. For the crude protein there was a significant effect among genotypes studied, with values ranging from 11.56 to 7.90%. The genotypes studied were equivalent in both the evaluation of the plants and the evaluation of silage, which can be used as an alternative fodder in semiarid regions.
