Abstract

QUEIROZ, Domingos Sávio et al. Cultivars and sowing dates of pearl millet for forage production. Rev. bras. saúde prod. anim. [online]. 2012, vol.13, n.2, pp.318-329. ISSN 1519-9940.  https://doi.org/10.1590/S1519-99402012000200003.

Aiming to evaluate the forage production and chemical composition of pearl millet (Pennisetum glaucum (L.) R. Br.) during rain/drought and drought/rain period transitions, without irrigation, this experiment was carried out at EPAMIG of Leopoldina-MG. Treatments were arranged as a 3x5 factorial: pearl millet cultivars: Comum, BN2 and BRS1501 and sowing dates (February, March, April, August and September). There was no differences among cultivars in dry forage mass production, with average of 4,010 kg/ha. There was difference among cultivars in crude protein (CP) and the in vitro dry matter digestibility (IVDMD). The CP values ranged from 14.04 to 17.95%, while the neutral detergent fiber variation was from 48.78 to 57.27% and the IVDMD was from 61.37 to 72.68%, according to the cultivars and sow time. There were differences among sow dates, with dry matter production of 3,941; 2,525; 4,316; 3,258 and 6,010kg/ha in the sowing dates of February, March, April, August and September, respectively. Anycultivar may be choosed, because the variations that were found in the chemical composition among cultivars according to sowing dates were variables. The production was better for sowing in September without changes in chemical composition of forage.
