This study was to assess the effect of different nutrient sources on the agroeconomic performance of potato (Solanum tuberosum var. Dosa) to offer farmers a more economical and sustainable alternative. For this purpose, an experimental device in completely randomized blocks with three sources of nutrients (mineral NPK fertilizer, green Tithonia diversifolia and laying hen droppings) was used. He had six (6) treatments and 3 repetitions. The treatments were defined in such a way as to satisfy the potassium requirements at a rate (180 kg/ha of K2O) necessary for the cultivation of the potato. The different treatments applied were: T0: Control, T1: Tithonia diversifolia, T2: chicken droppings, T3: mineral fertilizer, T4: (½Tithonia diversifolia+ ½ mineral fertilizer), T5: (½ chicken droppings +½ mineral fertilizer). The data collected on the growth variables (number of leaves, height of the plants, diameter at the collar, plant cover) and yield were subjected to analyzes of variance (ANOVA) and multiple comparisons of the means according to Duncan's test at the 5% threshold have been carried out. To test the profitability of the treatments used, an economic analysis was carried out. 

The treatments varied significantly between them. However, the results showed that: Treatments T2 and T5 were the most favorable to potato growth and yield. The highest yields were obtained respectively with treatments T5 (36.7 t/ha) and T2 (35.53 t/ha). T1 treatments; T4 and T3 gave statistically similar yields respectively of (20.55 t/ha), (20.01 t/ha) and (16.62 t/ha) and the lowest yield was obtained with T0 (7.44 t/ha). 

The economic analysis showed that the organic treatments alone (T1 and T2) or combined with mineral fertilizer (T4 and T5) may be best suited to the farming environment because they obtained an acceptability index (AI) higher than 2. However, given the limited incomes of farmers in Cameroon, T1 treatments (Tithonia diversifolia) and T5 (½ chicken droppings + ½mineral fertilizer) are the most recommended. Cette étude avait pour but d’évaluer l’effet de différentes sources d’éléments nutritifs sur les performances agroéconomiques de la pomme de terre (Solanum tuberosum var. Dosa) afin de proposer aux paysans une alternative plus économique et durable. A cet effet, un dispositif expérimental en blocs complètement randomisés avec trois sources d’éléments nutritifs (l’engrais minéral NPK, l’engrais vert Tithonia diversifolia et la fiente de poule pondeuse) a été utilisé. Il avait six (6) traitements et 3 répétitions. Les traitements ont été définis de manière à satisfaire les besoins en potassium à raison (180 kg/ha de K2O) nécessaire à la culture de la pomme de terre. Les différents traitements appliqués étaient : T0 : Témoin, T1 : Tithonia diversifolia, T2 : fiente de poule, T3: engrais minéral, T4 : (½ Tithonia diversifolia+ ½ engrais minéral), T5: (½ fiente de poule +½ engrais minéral). Les données collectées sur les variables de croissance (nombre de feuilles, hauteur des plantes, diamètre au collet, couvert végétal) et de rendement ont été soumises à des analyses de variances (ANOVA) et des comparaisons multiples des moyennes selon le test de Duncan au seuil de 5% ont été réalisées. Pour tester la rentabilité des traitements utilisés, une analyse économique a été réalisée. 
Les traitements ont varié significativement entre eux. Toutefois, les résultats ont montré que : Les traitements T2 et T5 ont été les plus favorables à la croissance et au rendement de la pomme de terre. Les rendements les plus élevés ont été obtenus respectivement avec les traitements T5(36,7 t /ha) et T2 (35,53 t/ha). Les traitements T1; T4 et T3 ont donné les rendements statistiquement similaires respectivement de (20,55 t/ha); (20,01 t/ha) et (16,62 t/ha) et le plus faible rendement a été obtenu avec T0 (7,44 t/ha).
L’analyse économique a montré que les traitements organiques seuls (T1 et T2) ou combinés à l’engrais minéral (T4 et T5) peuvent être les mieux adaptés en milieu paysan car ils ont obtenu un indice d’acceptabilité (IA) supérieur à 2. Cependant, au vu des revenus limités des paysans au Cameroun, les traitements T1 (Tithonia diversifolia) et T5 (½ fiente de poule + ½ engrais minéral) sont les plus recommandables.
