Different levels of stover treatments ranging from O t/ha to 4.58 t/ha were applied in a randomized complete block design experiment. Application of 4.58 t/ha stover increased maize yield by 0.74 t/ha over a control treatment, where no stover was incorporated. Cumulative stover applications for the 1993 and 1994 seasons also contributed to a 1995 yield increase of 0.73 t/ha over the control treatment. Soil N% level was also increased by 0.034% in the 4.85 t/ha stover treatments over the 1994 and 1995 seasons. Very little improvement in soil organic carbon level was realized after two seasons of stover applications. Crop residue that is left in the field after harvesting maize, if properly managed, can replenish some of the soil nutrients such as nitrogen and maintain soil organic matter levels and can lead to maize yield increase.Collection: CIMMYT Publications Collection
