Biomass productivity of a forage crop based cropping systems involving C3 and C4 plants

Abstract

An investigation was undertaken at the College of Agriculture, Vellayani during 1987 to study the biomass productivity of guinea grass based cropping system involving C3 and C4 plants. The intercrops wars a C4 grass maize and a C3 legume cowpea. The intercrops were grown in different rows with and without sequential thinning. The experiment was laid out in Randomised Block Design with three replications. After harvesting intercrops guinea grass was allowed to grow without subsequent intercrops. Total biomass yields upto third out of guinea grass were subjected to evaluation.
