Effect of Pigeon Pea Hedgerow Alley Management on the Growth and productivity of Ginger in a Tropical Ultisol in South Eastern Nigeria
Abstract
Growth, yield and yield attributes responses of ginger were assessed in a two-year (2010 and 2011 cropping seasons) field investigation conducted at the National Root Crops Research Institute, Umudike, South Eastern Nigeria. Treatments comprised three pigeon pea hedgerow alley populations of 20,000, 33,333 and 66,667 plants/ha in factorial combinations with three inter row alley spacings of 1m, 2 m and 3 m fitted into a randomized complete block design with three replications. Results showed that optimum performance in terms of plant height, number of leaves and number of tillers/plant and fresh rhizome yield of ginger were obtained with pigeon pea population of 20,000 plants/ha spaced 2 m apart. Although ginger plant height, number of leaves and number of tillers/plant, and fresh rhizome yield were relatively reduced in the pigeon pea treatments relative to the control, planting ginger within hedgerow alleys of pigeon pea resulted in an improvement in the productivity of the system in addition to significant reductions in the incidence of yellow leaf spot disease occurence of ginger.
