EFFET DE LA FERTILISATION MINERALE ET ORGANIQUE SUR LE RENDEMENT EN FRUITS DU PIMENT (Capsicum annuum L.; SOLANACEAE) EN ZONE FORESTIERE DE BASSE ALTITUDE AU CAMEROUN

摘要: A study on the effect of mineral and organic fertilizations fruits yield pepper ( Capsicum annuum L.) was carried out in Cameroon. Three types fertilizers: urea (46 %N), single superphosphate (16 %P2O5), potassium sulphate (48 %K2O) were used alone, or combination with each other a bulk fertilizer NPK (19-4-16) also formulated order to optimize fruit yield. Poultry manure as fertilizer. During crop growth, plant height, canopy width, planting-flowering interval, flowering-fruiting period number weight harvested measured. The results show that bulking 3 fertilizers, applied 4 times during cropping produced highly significant effects all growth parameters. Significant differences observed parameters reproduction when period. Furthermore, NPK, regularly broadcasted under canopy, gave highest This latest treatment yielded income benefit-cost ratio. fertilization had higher ratio than many chemical treatments.
