Abstract: A field experiment was conducted at two locations (Bolosso Sore and Damot Sore) in Wolaita Zone, Southern Nations Nationalities and People’s Regional State to evaluate the response of varieties haricot bean (Phaseolus vulgaris L.) with two rates of lime ( 0 and 0.4 t ha-1 CaCO3) used on acidic soils. The treatments were arranged in factorial RCBD with three replications. Analysis resulted of soil samples showed that organic carbon, availabile phosphorus, total nitrogen and soil pH values were very low. Application of lime resulted in significant changes on these chemical properties of the soils in the two locations. Availability of P and soil pH was improved due to the application of lime and maximum values of these parameters were recorded. Growth parameters, yield and yield components were significantly increased with increasing rates of liming at the two locations. Maximum grain yields (1282.49 and 1416.99 kg ha-1 for Hawasa Dume at Gununo and Dolla, respectively and 1079.40 and 1122.58 kg ha-1 for Omo-95 at Gununo and Dolla, respectively) were recorded with rates of 20 kg P ha-1 with lime (0.4 t ha-1) at both locations. From the result of this study it could be conclude that liming improve soil pH, availability of phosphorus and performance of haricot bean varieties but till now there is some gap on correcting acidity of the soils and also grain yield of the varieties. So application of lime should be repeated in the coming season until soil comes to neutral and increased the production of the crops.
