Abstract

A field experiment to study the effects of plant spacing (45x30cm, 35x30cm, 25x30cm and 15x30cm) on the growth and yields of Bambara groundnut varieties (EXMFI, EXMF4, IITA165 and ENZK1) was conducted in the School Farm of Ogbaru High School, Ogbakuba in Anambra State. The experiment was designed with split-plot in a randomized complete block design replicated three times. The main plots were assigned to Bambara groundnut varieties (EXMF1, EXMF4, IITA165 and ENZK2), while sub-plots were assigned to plant spacing (45x30cm, 35x30cm, 25x30cm and 15x30cm) with population densities of 7,407, 9,524, 13,333 and 22,222 plants/ha respectively. Results showed that the number of pods per plant, pod weight and grain yields of Bambara groundnut increased with decrease in plant spacing. Plants with spacing 45x30cm had the least yield of 2455 kg/ha, where as the best yield results were from plants spaced at 15x30cm with the mean value of 3939 kg/ha. Furthermore, variety EXMF4 had the highest yield of 3384 kg/ha but was not significantly different (P
