While number of primary branches(NPB) was determined by counting each from five randomly sampled
plants at harvest. The capsule yield(CY) was determined by weighing the fully dried harvested capsules from the
five randomly sampled plants. The CY were threshed and the realised clean seed was weighed to determined
grain yield per plant(GY/P). The grain yield per hectareG/ha) was determined from the harvest of each net plot
and converted to per hectare. Data collected were subjected to analysis of variance (ANOVA) using Stastical
Analysis Agricultural Sciences (SAS) and the means were compared using Duncan Multiple Range Test (DMRT)
(Duncan, 1955)
