English to Italian Science Agriculture

Corso di e-learning relativo all'agricoltura. Si parla di quando effettuare il raccolto delle colture.

Crops do need to be harvested when the moisture levels are correct.
For example, rice must be harvested at 20-25% grain moisture when the grains in the lower part of the panicle are in the hard doe stage and 80-85% straw colored which is approximately 30 days after flowering.

Qualche idea? Grazie mille
