Optimizing inputs for winter durum wheat in Ontario

Abstract

. 2015. Optimizing inputs for winter durum wheat in Ontario. Can. J. Plant Sci. 95: 361Á368. Best management practices need to be determined for a new wheat class in Ontario: winter durum. The objectives of this study were to determine optimal nitrogen rates (75, 100, and 125 . Grain yields did not increase with N rates higher than 100 kg N ha(1 , and the response to N rate did not depend on the application of fungicides. Grain protein concentrations increased with N rates up to 125 kg N ha(1 , which was the highest N rate investigated in this study. An economic analysis is needed to determine the impact of agronomic management strategies specific to winter durum wheat in Ontario. Le rendement grainier n'augmente pas avec le taux d'application des engrais azote´s une fois que celui-ci de´passe 100 kg de N par hectare, et la re´action a`la quantite´d'engrais applique´e ne de´pend pas de l'usage de fongicides. La concentration de prote´ines dans le grain augmente avec le taux d'application des engrais N jusqu'a`125 kg de N par hectare, taux le plus e´leve´examine´dans le cadre de cette e´tude. Il faudrait entreprendre une analyse e´conomique pour ve´rifier l'impact des strate´gies agronomiques particulie`res a`la culture du ble´dur d'hiver en Ontario.

“…In a similar way, Kilic and Gursoy (2010) found that 253 seeds m –2 had the greatest yield when studying a range from 50 to 550 seeds m –2 . Tamburic‐Ilincic et al (2015) observed no effect of greater seeding rates, although the range was narrow, from 400 to 480 seeds m –2 , which is a rather dense seeding rate, and was with winter durum. Conversely, Arduini et al (2006) and Isidro‐Sánchez et al (2017) observed increased yield with increasing seeding rate, the latter spanning a 2.3× rate.…”
