The effect of four leguminous plants on the productivity of Coffea canephora var. Robusta in Togo
With the aim of identifying efficient forest leguminous plants capable of improving soil fertility and protecting the environment in coffee growing in Togo, four species (Erythrophleum guineensis [E. suaveolens], Albizzia adianthifolia (Albizia adianthifolia), A. lebbeck and Samanea saman) were tested in 1995 at the CRA-F station at Tove. They were compared to an absolute control (without fertilizer) and to a reference control (usual fertilizer dosage). After the 1998 and 1999 harvest seasons, the experimental field suffered drought in 1999-2000 and the plants had to be pruned. This situation permitted: the measurement of the aptitude of the species to protect the coffee plant in the event of a prolonged drought (mortality readings); the evaluation of the capacity of leguminous plants to improve on the fertility of the soils (analysis of soil samples); and the measurement of productivity (yields). The results showed clearly that A. lebbeck was the best leguminous plant to protect coffee plants (4.16 percent mortality rate), support productivity (1261 kg/ha of marketable coffee).
