Dissertação (Mestrado em Agronomia) - Universidade Federal de Goiás, Jataí, 2013.http://repositorio.bc.ufg.br/tede/handle/tde/2939To evaluate the chemical composition and production of pearl millet (Pennisetum glaucum (L.)) at different sowing densities and managed under different cutting heights, a field trial was carried out at Santa Rosa do Rochedo farm of Universidade Federal de Goiás Campus Jatai, from March to July (second-season) after soybean harvest. A completely randomized block experimental design in factorial arrangement (3x2) with three sowing densities (10, 15 and 20 kg.ha-¹) and two cutting heights (50 and 70 cm) was used. Data were analyzed with SAS® v.9.2 program (SAS Institute Inc., Cary, NC) considering density effect and block in the plot and height in the subplot. Tukey test at 5% probability was used for mean comparison. The sowing density affected (P<0.05) CP percentage (13.98, 13.07 and 12.73 for 10, 15 and 20 kg.ha-¹ densities respectively). The cutting height influenced (P <0.05) chemical composition and production when compared one cut of each height, lower values of NDF (60,3%), ADF (35,7%) and higher levels of MM (8,8) and NFC (15,5%) were observed at 50 cm height cut. There were no effect (P> 0.05) of sowing density and cutting height on total yield during the experimental period. Due the better nutritional quality with longer period of pasture utilization and lower deployment cost, the use of pearl millet for grazing in the southwestern Goiás is feasible at sowing density of 10 kg.ha-¹ and height cut of 50 cm.application/pdfAcesso abertoSafrinhaRuminantesPennisetum glaucumForragensForagesPennisetum glaucumRuminantsCIENCIAS AGRARIAS::AGRONOMIADissertação
