On Farm

SUMMARYThe possible use of tropical forage legumes in pastures based on Brachiaria decumbens and Andropogon gayanus pastures was tested on farms in the humid tropics region of Pucallpa, Perú. The pastures were established by farmers using manual labour. They were associated with maize in some cases and were normally grown without fertilizers. The pastures were established in areas where fallow regrowth was felled and burnt. These pastures, with grass-alone controls, were incorporated by farmers into their normal paddock rotation and were grazed by dual-purpose cows. Despite the variable terrain and soil conditions, all the pastures established and persisted well. Over a four year period under grazing, the legume contribution to the forage averaged 21% and ranged between 1 and 66%. Desmodium ovalifolium was the dominant legume in paddocks that were not burnt, whereas in pastures regularly burnt to control weeds it tended to disappear and Stylosanthes guianensis was the main legume present. It is concluded that where farmers ensure the maintenance of adequate levels of forage, grass-legume mixtures are a viable and persistent option even if the pasture is occasionally burnt.

Commercially Important

Genetic transformation though protoplast electroporation has been established for commercially important plant species. In this work, explant sources, electric field strengths, electroporation buffers, DNA forms and osmotic pretreatment were assayed in order to optimize transient reporter gene expression in electroporated tissues of Stylosanthes guianensis, a tropical forage legume. Higher transformation rates were obtained employing cotyledonary explants and an electric field strength of 250 V cm-1. Linear plasmid DNA, chloridefree electroporation buffer and osmotic pretreatment with 1.6 mol L-1 mannitol also improved transient transformation but non-significantly. Transgene specific PCR amplification was employed to prove the transformed status of the tissues.

The study was designed to evaluate the dry matter yield and quality of two temperate (T. Pratense and T. repens) and two tropical forage legumes (S. guianensis and C.molle) harvested at early-flowering stage for hay in a cool tropical environment of Vom, Jos, Plateau State, Nigeria. The legumes were planted in the month of June, 2015 and 2016 in a 4 x 4 Latin Square Design with four replicates in plots measuring 5 m x 3 m. The forages were harvested at early-flowering stage for yield components, dry matter yield and nutrient quality evaluation. The result showed that C. molle was significantly (P<0.01) higher in height in the two seasons compared to the other legumes. Number of leaves per plant was higher (P<0.01) significantly in S. guianensis (125.00) in 2015 whereas, T. repens had higher (P<0.01) value (187.25) in 2016 cropping season.  Stylosanthes guianensis produced significantly (P<0.01) higher dry matter with 10.42 t ha-1 in 2015, while the dry matter yield obtained from C. molle (2.90 t ha-1) was the highest in 2016. Trifolium pratense and T. repens were scored excellent grade, while Stylosanthes guianensis and Centrosema molle were scored good in quality. Crude protein content was significantly (P<0.01) higher in T. repens (18.38%) compared to T. pratense (16.50 %), whereas S. guianensis produced the least value of 13.83%. The crude fibre content of the of the forage materials on the other hand was significantly higher (P<0.0I) in S. guianensis (37.29 %) compared to the other forage legumes. The temperate forage legumes in this trial were higher in nutrient content, but lower in dry matter yield. Therefore, the forage crops may serve as better supplementary feeds for livestock feeding especially during the dry season.
