Abstract:


The study was to investigate planting methods and seeding
rates appropriate for early growth (height, dry matter and
persistence of three Tephrosia species. It was a 3 x
3 x 2 factorial experiment in a split – split plot design
replicated 4 times, at an altitude of 1300m a.s.l. The
Tephrosia
species were; T. candida T. purpurea and T.
vogelii
. Planting methods were broadcasting, drilling
and space planting while planting densities were 10kg/ha and
20kg/ha. Leaf retention on the plant in the dry season was
scored on scale of 0 (no leaves on the plant) to 9 (most or
all leaves on the plant). The highest plant height (207.32
cm) was observed with T. purpurea and least (106.51
cm) with T. candida. Plants were tallest (172.59 cm)
under drilling and least (106.51 cm) under broadcasting.
Planting density did not significantly influence plant
height. Leaf retention by T. candida was
significantly higher (P <0.05) than those of T. purpurea
and T. vogelii. Leaf retention was highest under
broadcasting planting method. T. purpurea and T.
vogelii
produced more litter than T. candida.
Planting methods did not influence the amount of litter
produced by the species. In terms of growth as measured by
plant height, and DM yields, T. purpurea and T.
vogelii
performed better than T. candida. T.
purpurea
and T. vogelii are recommended for soil
fertility improvement while T. candida could be used as
browse under adverse climatic conditions.
