Description

This experiment, conducted at the Federal University of Agriculture, Abeokuta, Nigeria evaluated the morphogenesis of three varieties of Pennisetum purpureum used in this study, which were the local, purple, and FI variety at different stages of growth. The plants were established through vegetative plant parts (stems) sourced from a previously established plot and planted using 1 m × 1 m spacing on plots measuring 4 m × 5 m. The plants were fertilized with split doses of poultry manure at 4 t/ha (equivalent to 120 kg N/ha). The experiment was laid out as a Randomized Complete Block Design. Data on the morphogenic traits and dry matter yield were collected at bi-weekly from the 4th week for a period of twelve weeks. Results showed that the morphogenic plant traits differed significantly (p< 0.05) between the varieties, except the tiller appearance rate (p> 0.05) which was not significantly (p> 0.05) different when the varieties were compared. The purple variety had the least plant elongation and leaf appearance rate values, however, for both traits, the F1 hybrid and local variety had similar trait values. The F1 variety had the least (p< 0.05) leaf elongation rate value and the highest leaf (p< 0.05) expansion rate value. On the other hand, the local and purple variety had comparably higher leaf elongation rate and leaf expansion rate values. The purple variety had higher (p< 0.05) dry matter yield at the 6th and 8th week, but at the 10th and 12th week, the local variety produced the highest dry matter yield. In conclusion, the varieties had distinct morphogenic traits. Also, while the purple variety produced higher dry matter yield at the early stages of growth, dry matter production was higher for the local variety at more advanced stages of growth (10 and 12 weeks).

Evaluation of Morphogenesis and Yield of Three Pennisetum purpureum Varieties in South-West, Nigeria
