Net Primary Productivity (NPP) is the rate at which biomass accumulate per unit area per time, minus amount of organic materials used for autotrophic respiration. This study aimed at determines the influence of edaphic fertility on herbaceous NPP. Soil samples were collected using soil auger at 0-15cm depth, and chemical parameters were analysed using standard methods. NPP was determined in 400 (1m x 1m) randomly selected quadrats, by clipping aboveground biomass of central 20cmx20cm quadrats and digging 40cm depth for collecting belowground biomass using hands and forceps. Fresh biomasses were oven dried at 650C for 2days. Soil chemical properties were statistically significantly (P<0.05) higher in Site A, with pH (7.31±1.57), N (0.16±0.05%), P (12.33±0.93), Na (0.13±0.10), Mg (0.85±0.21), Ca (6.33±0.31), CEC (7.35±0.61), OC and OM had 0.45±0.02% and 0.77±0.01% respectively, but highest value of K (0.17±0.01) was recorded in Site D. ANPP shows a gradual increase from 15.00±2.5gm-2/month in June to 154.03±11.23gm-2/month in September, while BNPP ranges from 7.34±1.22gm-2/month in June to 62.81±6.39gm-2/month in October and the results was significant between the months (p<0.05). Between the Sites NPP varies significantly (P= 0.0198) and increase in the following trends; C<D<B<A with 138.8±10.01gm-2/month), 142.73±13.55gm-2/month, 148.5±8.51gm-2/month, 189.54±14.67gm-2/month respectively while BNPP was not statistically significant between the study Sites (P= 0.282). NPP is higher in edaphic fertile and neutral to slightly basic soil (pH= 7.31±1.57) than strongly acidic or basic soil. Further research on NPP of the most dominant species and the effect of climatic variables on NPP should be conducted.
