Calendula and camelina response to nitrogen fertility – J.M.F. Johnson and R. W. Gesch – Industrial Crops and Products – 2013

Summary: Calendula (Calendula officinalis L.) and Camelina (Camelina sativa L.) can provide a domestic, renewable, non-food alternative to imported oil sources for bioenergy and industrial purposes. However, limited information exists concerning N fertilizer guidelines for these emerging oilseed crops. Therefore, a replicated greenhouse study was conducted to assess the growth and yield response of calendula and camelina to N fertility. Study suggests maximum agronomic yield may compromise economic return, which needs to be considered when developing fertilizer recommendations for field production of these two oilseed crops. Link:
