For cowpea
Number of pods per plant: The number of pods per plant were counted from the five taken
sample plants.
Number of seeds per pods: The number of seeds per pod were determined from 20 pods taken
from the five sampled plants.
Grain yield: was determined from the net harvestable area and converted into adjusted yield by
using this formula Adjusted yield=AGY-(AGY*0.1)
100 seeds weight (g): weight of 100 seeds were randomly obtained from samples used for grain
yield analysis.
Harvest index (HI): This was the ratio of grain yield to aboveground biomass multiplied by
100.
HI =
Grain yield
Aboveground biomass
x 100
3.7. Land Equivalent ratio (LER)
Land Equivalent Ratio (LER): the ratio of the area under sole cropping to the area under
intercropping needed to give equal amounts of yield at the same management level. It is the sum
of the fractions of the intercropped yields divided by the sole-crop yields (FAO, 1976).
Relative yield was first determined by dividing intercrop yield of each crop by yield of sole crop.
From the sum of relative yields the land equivalent ratio (LER) were calculated mathematically as
follows as described by (FAO, 1976)
