Abstract:
Aimed to evaluate the productive performance and the quality of millet (Pennisetum glaucum L), planted in off-season under no-tillage (PD) regime, in three cutoff frequencies (FC 1, cut-off at the end of the cycle). HR 2 cuts at 45 days after emergence (DAE) and at the end of the cycle and HR 3 cuts at 30, 60 DAE and at the end of the cycle). A completely randomized design with four replications was used. The cultivar ADR 500®, planted on January 29, 2010, was used. The FC 3 treatment produced 3719.75 kg/ha, the FC 2 1289.92 kg/ha and the FC 1 2359.33 kg/ha. Decreasing values were observed in the percentage of crude protein (CP) in FC3 treatment sections and increasing of neutral detergent fiber (NDF) and acid detergent fiber (ADF). In conclusion, the environmental effects, low rainfall, photoperiod decrease and temperature drop harmed millet regrowth, but it can be used for a short period, 30 to 45 days, with good quality forage supply with residue left over for the next crop PD.
