Molybdenum, row spacing, plant population and PGRs in Faba beans

By Damian Jones, ICC Key messages: Applying molybdenum to faba beans did not effect nodulation or plant moly levels. Faba beans sown at 25 plants/m² on 7½ inch row spacings produced the highest yields. PGRs had no effect on the yield, height … Continue reading
