The Contribution of Crop Residues in Sustainable Production of Maize and Groundnut in a Crop Rotation System

Field and laboratory experiments were carried out with the main objective of studying the contribution of crop residues in sustaining yields of maize (Zea mays L.) and groundnut (Arachis hypogaea) in a crop rotation system under Malaysian tropical conditions. Five cropping seasons of a rotation o...

Also, two incubation studies were conducted in the laboratory, first, to determine potential N mineralization rates from above and below ground crop residues and second to determine potential N - mineralization rates of maize stover and groundnut haulm in selected five Malaysian soil series.
