Seed size can vary significantly, making planting by weight or volume alone a rather untrustworthy endeavour. So it's no wonder calculating seeding rates based on the thousand kernel weight (TKW) of the desired crop is advised by so many researchers and agronomists. In this Wheat School, Richard Marsh of Syngenta re-joins Lyndsey Smith to compare... Read More

The pea leaf weevil can cause devastating economic losses to both peas and faba beans. Though the adult beetles feed on these crops after overwintering in perennial legumes, it is actually the larvae that cause the greatest damage. Larval feeding occurs on Rhizobium nodules for roughly six weeks. This may limit or completely inhibit nitrogen-fixation... Read More
