CONTRERAS, Vicente  y  OCHOA, Ángel. Short and thick stakes: An agronomic option for vegetative sowing of Gliricidia sepium. Zootecnia Trop. [online]. 2003, vol.21, n.4, pp.413-424. ISSN 0798-7269.

Summary To improve the agronomic efficiency in the asexual propagation of Gliricidia sepium, two essays were installed: one at La Colorada on 04-24-98 , and the other at La San Juana on 07-29-98 , both of them located in Colón ( Pre Mountainous Humid Forest ), Táchira state, Venezuela . In the first essay, a completely randomized factorial 3x3 design with three replicates was conducted, where treatments were stakes length: L1=10, L2=15, and L3=20 cm, and diameter ranges, D1=2.5-3.5, D2=3.6-4.5, and D3=4.6-5.5 cm. In the second essay, 10 replicates in a completely randomized design where treatments were stakes length: M1=8 and M2=10 cm, and diameter ranges: E1=5.0-6.0, E2=6.1-7.0, and E3=7.1-8.0 cm. In the first essay, sprouting occurred 22-37 days after sowing. In the second essay, sprouting occurred 9-60 days after sowing. In stakes £20 cm length it was evident that the diameter had a direct influence on sprouting. The probability of sprouting of short stakes with diameters <4.5 cm was practically null. Stakes of 10 cm length with diameters >5 cm showed the highest agronomic efficiency. In those stakes, sprouting ranged 90 to 100%.
