Response of Faba Bean (Vicia faba L.) to Phosphorus Fertiliizer and Farm Yard Manure on Acidic Soil in High Land of Tembaro Woreda, Southern Ethiopia

Abstract

Faba bean (Vicia faba L.) variety was evaluated for its performance upon the application of P (TSP) fertilizers and Farm yard manure in Tembaro Woreda  of Kembata Tembaro Zone in 2016 cropping season. This study was carried out with the objectives of investigating the optimum rates of P fertilizers (0,15,30,45 and 60 kg/ha) and FYM(0, 4 and 8 t/ha) for faba bean production on acidic soils. The experiment was laid out in factorial RCBD design with three replications. The data collected were plant height, tillers per plant (productive  & Non-productive), Pods per plant, Seeds per pod, grain yield, biomass and hundred  seed weight. In the analysis of variance some of the parameters such as tillers per plant, Seeds per pod, pods per plants, total biological yield and grain yield showed significance difference (p<0.05, 0.01, 0.001). In the mean comparison analysis for significant parameters, the FYM with the rate of 4 and 8 t/ha combined with 60 kg/ha P fertilizer performed better than that other combinations. Application of FYM modified after harvesting the soil chemical properties such Soil P^H, TN(%), Av.P(ppm), OM %  and CEC (meq/100g) showed variation before sowing 5.21, 0.43, 6.7, 5.7 and 24,  after harvesting  6.31, 0.39, 8.2, 7.8 and 32  ,respectively and soil physical properties such as particle size distribution, water holding capacity, bulk density and soil porosity. Soil water holding capacity showed variability at Tembaro site before sowing (FC=34,  PWP=20, WHC=14) and after harvesting (FC=44,  PWP=23, WHC=21). The soil acidity changed from strongly acidic to moderately acidic after harvesting.
