Evaluation of New Fall Rye Cultivar ‘Bono’ in Single and Double Cropping Systems

A new fall rye (FR, Secale cereale L.) cv. Bono was investigated as a novel cropping option in Saskatchewan, Canada. In this study, the performance of compared to Hazlet FR, and both cultivars were winter triticale (WT, Triticosecale Wittm.) Pika single (SC) or double (DC) systems with spring barley (Hordeum vulgare evaluated Dark Brown soil zone, 2019–2021. Five replicated (n = 4) treatments were: (i) BonoFR; (ii) HazletFR; (iii) PikaWT; (iv) Barley–BonoFR; (v) Barley–HazletFR. The first crop harvested at soft dough stage, followed by second FR seeded same year between flag leaf heading emergence following summer for greenfeed hay. did not differ (p > 0.05) DMY (1.2 Mg ha−1) nutritive value from Hazlet, however, FRs differed 0.01) WT higher nitrogen use efficiency (NUE, 41.0 vs. 33.7) NDF (541.8 479.3 g kg–1), but lower CP (155.3 187.1 kg–1). Double ryes increased total DMY, nutrients yield per ha, minerals uptake up 83% NUE 35.3%. conclusion, could be an equal quality alternative although current seed price may delay its adoption.
