Ten (10) cowpea varieties exposed to alpha nano spin were evaluated
during the 2019 cropping season to access the role of alpha nano spin in their
growth and dry matter accumulation at the Botanical garden of Federal
University, Lafia. A Randomized Complete Block Design (RCBD) with four
replications was used. The fourth replication was used for the destructive
sampling over time. The seed was exposed to alpha nano spin before planting at 0, 20, 40 and 60 minutes
respectively. Results of the study showed that the varieties differed
significantly with respect to morphological traits studied (P < 0.05) as exposed
to the alpha nanoparticles. Morphological traits such as vine length, number of leaves and above
ground stems were significantly influenced by alpha nanospin bombardment. 40mins alpha nano spin resulted
in maximum accumulation of dry matter, leaf area and leaf area index. The
traits evaluated were stable under alpha nano spin exposure, suggesting that
they could be useful indices in creating genetic variability in each of the
varieties.
