Abstract

Growth and yield parameters of bambara groundnut [Vigna subterranea L. Verdc. landraces: White Seed Coat (WSC), Black Seed Coat (BSC) and Light Red Seed Coat (RSC)] were evaluated under organic and inorganic fertilization in order to determine the field performance, for the improvement of smallholder agriculture in Cameroon. Four fertilizer application rates (0, 3, 6 and 12 t ha-1) of Water Lettuce (WL) and Poultry Manure (PM) and four fertilization rates (0, 100, 150 and 200 kg ha-1) of N, P and K were used in a randomized complete block design experiment with four replications. Application of WL or PM at 12 t ha-1 significantly (p<0.001) increased leaf water content, plant dry weight and total chlorophyll content in RSC landrace. Application of PM at 12 t ha-1 increased significantly (p<0.001) the number of pods per plant, the number of seeds per pods, the 1000 grain weight, the grain yield and the pod yield in RSC landrace. Significant (p<0.001) increase in plant dry weight was observed in all landraces at 100 kg ha-1 N, P or K fertilization. The fertilization rates above 100 kg ha-1 N, P or K led to a decline in yield in all the bambara groundnut landraces compared to the optimum 100 kg ha-1 N, P or K fertilization. RSC landrace showed better growth and yield than WSC and BSC landraces revealing a greater response of this cultivar to fertilization.
