Influence des amendements calcaire et organique sur le rendement de l'arachide en sol acide dégradé au Sénégal

The influence of organic and calcareous amendments on yield of groundnut produced on acid degrated soils, in Senegal. Trials were carried out during the 1984 and 1985 seasons to determine the influence of organic matter and liming on low feriility acid soils using groundnuts as an indicator. Results indicated that groundnuts have a wide tolerance to variation in pH. Horse manure applied in 1984 had a significant influence on yield, reduced the rate of plant mortality, and had a positive residual effect in 1985. Peat mixed with either manure or commercial fertilizer increased yield, but to a lesser extent than manure alone because of its specific characteristics however, further testing of these treatments is under way
