Popis: One of the challenges to potato (Solanum tuberosum L.) production systems is to reduce N applications without incurring any marketable yield penalty. From previous studies, it was established that red clover (Trifolium pratense L.) can encourage the development of beneficial rhizobacterial communities that promote potato growth and development, in essence making agricultural soils as or more productive for specific quality attributes. In the present 2-yr study, we examined the influence of the red clover cultivars AC Charlie, AC Endure, AC Kingston, Atlas, Marino, and Prosper on the potato cultivars Kennebec, Russet Burbank, and Shepody, grown in the following season. We found that the preceding clover cultivar had no influence on either Kennebec or Russet Burbank. However, Shepody potato following AC Kingston showed a significant yield advantage (P = 0.05), in tonnes per hectare, over other clover cultivars (except Atlas) in the Size 2 category of tubers (tubers >51 mm in diam. and
