Bean production and fusarium root rot in diverse soil environments in Iran

The associations of Fusarium root rot (FRR) and yield variables with a number of soil characteristics were determined at pod maturity in 122 commercial bean fields in Zanjan, Iran. Mean pod and seed numbers per plant at a sand content level of 45-65% were lower than those at a level of 25-45%. Highe...
