  A field experiment was conducted at two locations (Bolosso Sore and Damot Sore) in Wolaita Zone of SNNPRS to evaluate the response of two varieties of haricot bean (Phaseolus vulgaris L.) with two rates of lime (0 and 0.4 t ha-1 CaCO3) were used on acidic soils. The treatments were arranged in factorial RCBD with three replications. Analysis result of soil samples showed that OC, Av.P, TN and soil pH values were very low. Application of lime resulted 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 (year 1 and 2). 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 at rates of 20 kg P ha-1 with lime of 0.4 t ha-1 at both locations. From the result of this study it could be conclude that liming improve soil pH, Av.P 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 soil until comes to neutral and increased the production of the crops.

  In Ethiopia, Agriculture still constitutes the major part of the country’s economy, yet the agriculture is facing a number of problems. Hence farmers are entangled in a vicious circle of ecological degradation, poverty and starvation. The causes to these rooted problems are the land degradation exhibited in form of soil fertility loss as initiated by different factors as deforestation, overgrazing and with a result of soil erosion, sedimentation, pollution, etc. The intention of this study is to discuss the status of soil fertility in country, the causes to soil fertility loss and find better solutions of soil fertility decline. As the topography of the country is rugged with varying types of soils, particularly the highland where about 90% of the arable land is concentrated, problems such as soil erosion, poor and continuous cultivation are the major causes to soil fertility decline. Therefore, the use of integrated soil fertility management with inclusion and combination of manure, compost, crop rotation, soil conservation practices such as minimum tillage, tied-ridging, residue management and other practices together with chemical fertilizer and improved germplasms gives the better production and keeps the soil fertility status to a better level. The practice being under taken by the Government which is the use of fertilizers in blanket recommendation is not successful as a result of agro-climate, soil and the socio-economic condition of the farmer, resorting to sustainable integrated soil fertility management to get maximum yield without compromising the soil fertility status in the future is wise and need to follow.
