Effects of Liming and Phosphorus Levels on Yield and Yield Components of Haricot Bean (Pharsalus vulgarism L.) Varieties on Nitosols at Wolaita Zone, Ethiopia

Abstract: A field experiment was conducted at 2 locations (Bolosso Sore and Damot Sore) in Wolaita Zone of SNNPRS to evaluate the response of 2 varieties of haricot bean (Phaseolus vulgaris L.) to phosphorus fertilizer rates and liming on acidic soils. Combinations of 4 levels of P (0, 10, 20 and 30 kg ha^-1) with 2 rates of lime (0 and 0.4 t ha^-1) were used on 2 varieties. The treatments were arranged in factorial RCBD with 3 replications. Analysis result of soil samples showed that OC, Av.P, TN and soil pH values were very low. Application of lime with P resulted significant changes on these chemical properties of the soils in the 2 locations. Availability of P and soil pH was improved due to the application of lime and maximum values of these parameters were recorded at 30 kg P ha^-1. Growth parameters, yield and yield components were significantly increased with increasing rates of P, both with liming and no liming at the 2 locations (year 1 and 2). Maximum grain yields (1488.40 and 1523.7 kg ha^-1 for Hawasa Dume at Gununo and Dolla, respectively and 1242.12 and 1352.01 kg ha^-1 for Omo-95 at Gununo and Dolla, respectively) were recorded at rates of 30 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 until soil comes to neutral and increased the production of the crops.
