Rye grain response to nitrogen fertilizer and seeding rate

Abstract Cereal rye ( Secale cereale L.) seed production is of increasing value in the United States, yet basic agronomic management practices specific to grain have not been established. Field research trials were conducted near Tifton and Midville, GA, during winter crop season 2017–2018 assess effects seeding rate spring‐applied N fertilizer on production. (cultivar ‘Wrens Abruzzi’) was planted at four rates (215, 323, 431, 538 m −2 ) top‐dressed with spring (0, 34, 67, 101 kg ha −1 a randomized complete block design replications. At both sites, yield responses added best described by linear‐plateau regression models. The response greater (following corn [ Zea mays L.]) than Midville peanuts Arachis hypogaea L.]), plateaued 44 67 , respectively. Lodging increased 31% addition also quadratically rate, which presumably contributed reductions higher (431 across sites. This work demonstrates potential optimize substantially lower inputs those recommended for other end uses (i.e., forage or cover crop) cereal species.
