Fungicides may be used as a last resort in cases of severe disease outbreaks.
Harvesting and Post-Harvest Handling
1. Determining Maturity and Harvesting Time
Determining the optimal harvesting time is crucial for maximising yields and minimising grain losses. The crop is typically ready for harvesting when the panicles turn brown and the grains become hard and difficult to dent with a thumbnail. Timely harvesting ensures that the grains do not shatter or sprout, which can lead to significant yield losses.
2. Harvesting Methods
Finger millet can be harvested manually or mechanically, depending on the scale of production and available resources. Manual harvesting involves cutting the panicles with sickles or knives, while mechanical harvesting can be accomplished using combine harvesters or threshers. Proper drying and threshing techniques should be employed to ensure grain quality and minimise post-harvest losses.
3. Storage and Processing
Proper storage and processing are essential to maintaining the quality and longevity of finger millet grains. Grains should be dried to safe moisture levels (10–12%) before storage to prevent spoilage and insect infestation.
