Dwarf Variety

The effects of short-day (SD) and gibberellic acid (GA3) treatments on promoting vegetative propagation during the summer were examined in Napier grass (Pennisetum purpureumSchumach). A dwarf variety of late heading type (DL) Napier grass was exposed to three SD treatments (5, 10, and 20 short days plus a spray of 400 ppm GA3solution following each SD treatment, GASD) or no treatment (control). Additionally, then, a dwarf variety of early heading (DE) and the normal variety of Merkeron (ME) were exposed to 10 days of GA-SD treatment together with nontreated controls. For DL and DE, GA-SD treatments showed the following effects: 10-day GA-SD treatment increased significantly (P<0.05) the length of lateral tiller buds, maintained a high rooting percentage, and increased the diameter of the tiller buds. This resulted in a taller plant, one with enhanced tiller numbers, and thus a greater number of established nursery plants for the two dwarf varieties. In contrast, there was only a limited positive effect of the GA-SD treatments on the normal variety, ME. Thus, 10 days of GA-SD treatment was judged to be the most effective treatment for promoting lateral tiller bud elongation and early maturation in tiller buds for the two dwarf varieties of Napier grass.

Cattle in the tropics mostly depend on pastures. During dry periods the forage available is usually mature, constraining both intake and digestion. These constraints need to be understood, for intake and digestibility define productivity. Intake depends on the rumen space made available by fermentation and outflow. Markers such as PEG (liquid phase), and chromium mordanted fibre (solid phase) can be used to measure rumen volume and outflow, but have limitations. The objective of this experiment was to measure intake, digestibility, and rumen kinetics of cattle fed ad libitum forages with very different degradation characteristics, and also to compare rumen volumes measured with markers with those obtained by manual emptying.

A trial was conducted to investigate the germination percentage and emergence potential of nine imported temperate forage germplasms at the National Animal Production Research Institute, Shika, Nigeria. The seeds consisted of seven grasses namely; Beefsteak plant (Fructus perillae), Sweet elephant grass (Pennisetum alopecuroides), Wild foxtail millet (Setaria viridis), Napier grass (Pennisetum purpureum), King grass (Pennisetum sinese), Chinese sorghum (Sweet sorghum) and Zea mexican schard (Purus frumentum) and two legumes namely; Chinese woad (Isatis tinctoria) and Chinese alfalfa (Medicago sativa). A laboratory germination test and pot emergence trial was carried out to ascertain their viability. The result of the experiment showed that Sweet elephant grass, napier grass and king grass recorded over 90 % germination and the least was 30 % in Chinese sorghum. Chinese alfalfa and wild foxtail millet had least germination percentage with 100 % Seed dormancy.Highest emergence rate, seedling length and seedling vigour indexwere observed in king grass than the other forage germplasms. The highest percentage emergence was obtained in king grass > sweet elephant grass > napier grass > Zea mexican schard > beefsteak plant > Chinese woad > Chinese sorghum, respectively. It was concluded that these forages can successfully be adopted as animal feed resources in Nigeria and therefore, recommended formulti-locational trials in all the ecological zones of the country.

Signal Grass

Signal grass (Brachiaria brizantha) and Giant Pangola (Digitaria valida Stent) were introduced into Puerto Rico by the Agricultural Experiment Station in 1957, from Ceylon and Cuba, respectively. Field observations and unpublished data on yields indicate good forage possibilities for these grasses for the Island. Both were submitted to a palatability test and compared with Napier grass, (Pennisetum purpureum), which is one of our most palatable forage grasses, using a 3 x 3 Latin-square design. The two grasses are as palatable as and contain more dry matter per pound of green forage than Napier grass. Both grasses are under grazing trials and must be submitted to more field observations before final recommendations are given to the farmers.

Plant-pathogenic phytoplasmas found in wild grasses in East Africa could pose a serious threat to the cultivation of Napier grass, Pennisetum purpureum, the most important livestock fodder in the region. To asses this threat, leaves from plants of 33 grass species were sampled from Mbita, Bungoma, and Busia districts in western Kenya; Tarime district in northern Tanzania; and Busia and Bugiri districts in the eastern Uganda to determine which species host phytoplasmas, the identity of the phytoplasmas, and their relationship with disease symptoms. Phytoplasmas were detected using universal primers based on conserved phytoplasma-specific 16S rDNA sequences from 11 grass species collected. Sequence and phylogenetic analysis revealed the presence of Napier grass stunt-related phytoplasmas in 11 grass species, ‘Candidatus Phytoplasma cynodontis’ in three, and goosegrass white leaf phytoplasma in 2 wild grass species. This study showed that the geographical distribution, diversity of phytoplasmas, and their grass host species in East Africa is greater than antecedently thought and that typical disease symptoms, including white leaf or stunting alone, are not reliable indicators of the presence of phytoplasma. It also shows the need to identify insect vectors responsible for phytoplasma transmission from native grasses to Napier grass or other cereals present in the region.
