Effect of liming and application of phosphatic fertilizer on growth and root nodulation of common bean in an old tea land was investigated. A field trial was conducted where tea had been uprooted after 70 years of monoculture under high inorganic fertilizer input. Lime was applied at 0, 4, 8 and 12 tonnes ha-1 and triple superphosphate at 0, 5, 10 and 15 g per planting hole. The treatments were combined in a factorial design and investigated for effects on the soil pH, nodule formation, and some plant growth parameters. Lime application raised the soil pH and also significantly (P= 0.05) increased dry matter production and nodule quantity. Phosphorus also increased dry matter production and nodule quantity significantly (P = 0.05). These observations are discussed in regard to ways of enabling bean crop grow on old tea lands.
