Response of a quality protein maize hybrid to N supply and plant density in the forest zone of Ghana

Maize yield was not significantly affected by increased plant density but it increased with nitrogen fertilizer. Economic analyses showed that the marginal rate of return in applying 90 kg N was 113–194%, while 135 kg/ha gave 120–248%. Copyright © 2005 Whurr Publishers Ltd.
