Evaluación ecofisiológica de trece leguminosas nativas con potencial forrajero para la producción animal en el Espinal, Tolima
The south of Tolima and north of Huila are regions with two dry seasons during the year and have a flora rich in native legumes whose potential has not been neither studied nor enough explored. For these reasons, in 1991 and 1992, seeds of these species were collected and then classified by dAT. In 1994B, a study was carried out at "Nataima" research center located at 40 12' N.L. and 74052 W.L., 431 m.a.s.l. with an average temperature of 28° C. 1.300 mm. of annual rainfall and classified as Tropical Dry Bosque. The main objective of this study was to evaluate eco-morpho-physiologically 13 genus of legumes which where classified, according to its growth habit in crawled and erect. The evaluation was based on climatic variables such as rainfall, temperature at 5 cm below soil and environmental temperature; the morpho-physiological variables leaf area and leaf dry weight were evaluated by using the semidesfrucfive analysis technique for analogy; and experimental design of complete randomized blocks with sampling was used. The results showed that Ga/act, striata with a cubic relationship for leaf area and leaf dry weight through the time, appears to be the best adapted followed by Macroptilfum atropurpureum. For erect legumes, Sty/osanthes sacbra with an equation adjusled to a cubic model for leaf area and leaf dry weight showed the best adaptation followed by Tephros/a c,ierea and Chamaecrista ro/und/folia. The expectation is to continue the agronomic evaluation of association or protein bank, as well as zootecnologic studies focussed to give to the farmers an alternative to their animal food problems and soils improvement.

| Summary: | The south of Tolima and north of Huila are regions with two dry seasons during the year and
have a flora rich in native legumes whose potential has not been neither studied nor enough
explored. For these reasons, in 1991 and 1992, seeds of these species were collected and then
classified by dAT. In 1994B, a study was carried out at "Nataima" research center located at
40 12' N.L. and 74052 W.L., 431 m.a.s.l. with an average temperature of 28° C. 1.300 mm. of
annual rainfall and classified as Tropical Dry Bosque. The main objective of this study was to
evaluate eco-morpho-physiologically 13 genus of legumes which where classified, according
to its growth habit in crawled and erect.
The evaluation was based on climatic variables such as rainfall, temperature at 5 cm below soil
and environmental temperature; the morpho-physiological variables leaf area and leaf dry
weight were evaluated by using the semidesfrucfive analysis technique for analogy; and experimental design of complete randomized blocks with sampling was used. The results showed that Ga/act, striata with a cubic relationship for leaf area and leaf dry
weight through the time, appears to be the best adapted followed by Macroptilfum atropurpureum. For erect legumes, Sty/osanthes sacbra with an equation adjusled to a cubic model for
leaf area and leaf dry weight showed the best adaptation followed by Tephros/a c,ierea and
Chamaecrista ro/und/folia. The expectation is to continue the agronomic evaluation of association or protein bank, as well as zootecnologic studies focussed to give to the farmers an alternative to their animal food problems and soils improvement. |
