Studies on the Growth of Leucaena leucocephala.-2. Effect of Lime at Sowing on Production from a Low Calcium Status Soil of the Sogeri Plateau.

Abstract

Leucaeza is difficult ,to establish on l_ow calcium status, acid soils of the Sogeri family on the Sogeri Plateau. The Peru strain of Leucaena was sown and lime applied at 1, 5 and 10 tons per acre broadcast, and at 1, 2, 4 and 8 cwt per acre drilled in the row. Significant responses were obtained to the application of 5 and 10 tons per acre (P < 0.05). As agricultural lime is not at this stage produced in Papua New Guinea, use of these high levels ,of lime cannot be considered economic.
