Abstract

Comparison of seedling containers on growth and survival of Prosopis alba and Leucaena leucocephala in semi-arid conditions.

Abstract

Growth and survival of Prosopis alba 0166 and Leucaena leucocephala K8 were compared under non-irrigated conditions in semi-arid south Texas using large dibble-tubes (Ray Leach Supercell) that were removed prior to transplant, or cardboard plant-bands that were not removed prior to transplant. A poorly prepared seedbed was used to enhance water stress. In 1983, no rain occurred within 6 weeks of planting and 387 mm occurred in the first 9 months after planting. In 1984, the first significant rain occurred 21 days after planting and 587 mm occurred in the first 9 months after planting. In the driest year (1983), Prosopis had about 25% greater survival than Leucaena and the plant-bands had 25% greater survival than the dibble-tubes for both Prosopis and Leucaena. In the wetter year, there were n.s.d. in survival among the container types or between the species.
