Abstract
A two-year (2009/2010) field study was conducted at the research field of the National Root Crops Research Institute, Umudike, Nigeria, to evaluate the effect of short duration grain legume crop integration into ginger-based system on ginger growth and yield responses and on soil quality. The possibility of replacing organic mulch procurement and application in ginger production in South Eastern Nigeria with in-situ grown live short duration grain legume crops from different sources was also evaluated. Treatments consisted of four legume sources (egusi melon, vegetable cowpea, cowpea variety 1696 and mungbean) each factorially applied at four population densities of 10,000, 20, 000, 40, 000 and 80, 000 plants/ha in a randomized Complete Block Design with three replications. A plot having no grain legume treatment but mulched with 20 t/ha Panicum maximum grass as practiced by local farmers constituted the control. Results showed that although in general, ginger establishment and plant height reduced significantly with the application of legume crops, integration of short duration grain legume crops into ginger-based system improved the organic matter, total N, available P and exchangeable K contents of the experimental soil relative to the control. Egusi melon and vegetable cowpea gave statistically same rhizome yield result with the control and showed greater prospects of being siutable alternative mulch sources to Panicum maximum for ginger production on the low fertility soils of South Eastern Nigeria. Optimum rhizome yield performance was achieved with 40, 000 legume plants/ha.
