Nitrogen Fertilization and Severity of Stem Rot of Rice. R. Keim and R. K. Webster, Department of Plant Pathology, University of California, Davis 95616. Phytopathology 64:178-183.

Field trials comparing the effects of foliar nitrogen levels and times of nitrogen (N) fertilizer applications on severity of stem rot of rice, indicated increased disease severity on plants which contained increased amounts of N.  Split N application, 28 kg/hectare (ha) (25 lb/acre) before seeding and 84 kg/ha (75 lb/acre) as a topdressing 84 days after seeding, delayed disease development and increased yield as compared with those plants receiving topdressings at earlier stages of rice development.
