GOMEZ, I; FERNANDEZ, J.L; OLIVERA, Yuseika  and  ARIAS, R. Effect of cattle manure on the establishment and seed production of Teramnus labialis. Pastos y Forrajes [online]. 2007, vol.30, n.2, pp.1-1. ISSN 0864-0394.

The effect of the application of five doses of cattle manure (0, 8, 16, 24 and 32 t/ha) on the establishment and seed production of the forage legume Teramnus labialis (Semilla Clara) was studied, on a Fluvisol soil of the Cauto Valley, which was sown in 30 m plots in August. During the establishment the area covered was measured, and in the reproductive stage the length of the pod, quantity of seeds per pod, total seed yield and yield of pure germinable seed (PGS) were determined. Significant differences were found in the cover percentage of this species 60 and 120 days after sowing, and the highest variability among treatments was reached with the lower age; while with higher age the doses from 8 to 32 t/ha were similar and they were higher than the control. Likewise, during the reproductive stage there was a trend towards the better performance with the organic applications as compared to the control, except in the total seed yield, because there were no differences between it and the application of 8 t/ha. The economic analysis showed statistical differences among treatments and the lowest cost of the kilogram of seed was obtained with the applications of 16 and 24 t of manure. The use of cattle manure as organic fertilizer was concluded to produce a positive effect, on the establishment of this species as well as on the pure seed yields, and the 16 t/ha dose is recommended for being the most productive and economical.
