A field experiment was carried out in central Italy in order to evaluate the effect of weed-infested and weed-free periods on French bean yield. Results showed that in order not to exceed a 5% yield reduction the critical period of competition occurred from 10 to 33 Days after Emergence corresponding to 87 and 323 Growing Day Degrees after Emergence (Tbase = 10°C). Weed competition decreased no. pods plant-1 whereas did not affect no. crop plant m-2, pod length and diameter.

Abstract
A field experiment was carried out in central Italy in order to evaluate the effect of weed-infested and weed-free periods on French bean yield. Results showed that in order not to exceed a 5% yield reduction the critical period of competition occurred from 10 to 33 Days after Emergence corresponding to 87 and 323 Growing Day Degrees after Emergence (Tbase = 10°C). Weed competition decreased no. pods plant-1 whereas did not affect no. crop plant m-2, pod length and diameter.File in questo prodotto:
