Harvesting your Maize Silage : Optimize Timing for Superior Quality
Two out of three farmers do not harvest at the right date – here’s how to get it right.
Harvesting at the Right Date
60% of farmers miss harvesting their silage maize at the right time, either because of hot and dry weather conditions in august and september or because of difficulties estimating the right stage.
The best stage to harvest silage maize is between 32 and 35% dry matter. The variation in moisture is a compromise between yield, plant composition, ease of silage production, silage conservation ability and desired ingestion level by the animal.
