While meat becomes a luxury food for the poor people, legumes including soya bean, can constitute an alternative. Unfortunately, on highly weathered soils of Lubumbashi, the performance of this crop remains far below the potential. The effects of compost of Tithonia diversifolia on growth and yield of soybean were studied during the 2013-2014 cropping season on degraded soil Lubumbashi (DR Congo). Under a basic fertilizer, six levels of compost of T. diversifolia (0, 7.5T, 15T; 22,5T; 30T; 37,5T ha) were applied as treatments in a completely randomized block design with 3 replications. The observations were focused on vegetative parameters and the yield of the crop. Similar behavior of soya bean plants was observed, regardless of the dose of compost made. Under the supply of mineral fertilizers, the supply of composts to soybeans mustn't be recommended given the low-income of farmers and the availability of composts.

Abstract
While meat becomes a luxury food for the poor people, legumes including soya bean, can constitute an alternative. Unfortunately, on highly weathered soils of Lubumbashi, the performance of this crop remains far below the potential. The effects of compost of Tithonia diversifolia on growth and yield of soybean were studied during the 2013-2014 cropping season on degraded soil Lubumbashi (DR Congo). Under a basic fertilizer, six levels of compost of T. diversifolia (0, 7.5T, 15T; 22,5T; 30T; 37,5T ha) were applied as treatments in a completely randomized block design with 3 replications. The observations were focused on vegetative parameters and the yield of the crop. Similar behavior of soya bean plants was observed, regardless of the dose of compost made. Under the supply of mineral fertilizers, the supply of composts to soybeans mustn't be recommended given the low-income of farmers and the availability of composts.

Abstract: (french)
A l'heure où la viande constitue un aliment de luxe pour les populations pauvres, les légumineuses entre autres le soja constituent une alternative. Malheureusement, sur les sols fortement altérés de Lubumbashi, son rendement demeure de loin inférieur au potentiel même de la culture. Les effets de compost de Tithonia diversifolia sur la croissance et le rendement de soja ont été étudiés au cours de la saison culturale 2013-2014 sur un sol dégradé de Lubumbashi (R.D. Congo). Sous couvert d'un engrais de fond, six niveaux de compost de T. diversifolia (0 ; 7,5T ; 15T ; 22,5T ; 30T ; 37,5T de compost de Tithonia diversifolia par hectare) ont été appliqués comme traitements, dans un dispositif en blocs complets randomisés à 3 répétitions. Les observations ont porté sur les paramètres végétatifs et de rendement et les résultats obtenus ont révélé un comportement similaire des plants de soja, quelle que soit la dose de compost apportée. Sous couvert d'engrais minéraux, l'apport des composts n'est pas à conseiller en culture de soja, au regard de faibles revenus des agriculteurs et disponibilité des composts.
