Nitrogen and sulfur fertilizers effects on growth and yield of <i>Brassica carinata</i> in South Dakota

Carinata (Brassica carinata A. Braun), a non-food oilseed and an alternative biofuel feedstock, has received attention for its potential as low-input option production in the semi-arid regions of Northern Great Plains (NGP). This study was conducted to (a) determine economic optimum N S fertilization rates (b) interactive effects on seed yield agronomic traits carinata. The field experiment 2017 2018 at Brookings, SD, had four (56, 84, 112, 140 kg ha?1) three (0, 22, 45 ha?1). Increasing rate increased oil each peaking 112 ha?1 both years. Applying fertilizer concentration over control but with two performing similar In absence application, reduced irrespective indicating that is critical obtain positive response fertilizer. Economically optimal ranged from 47 93 whereas 20 26 ha?1. 1.0 Mg 1.5 These findings suggest trait can vary depending availability soil.
