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. Keywords :- Farmyard manure, Triple superphosphate, treatments, replication DOI : 10.7176/JBAH/9-1-04
Highlights
Faba bean (Vicia faba L.) is among the major grain food legumes cultivated in different part of Ethiopia including Kembata Tembaro zone(CSA, 2013)
A study was undertaken on the effects five levels of P fertilizer and three level of air dried decomposed farmyard manure on growth,yield and yield components of faba bean
The study was conducted with the aim of evaluating the effects of P fertilizer with FYM on growth of Faba bean
Summary
Faba bean (Vicia faba L.) is among the major grain food legumes cultivated in different part of Ethiopia including Kembata Tembaro zone(CSA, 2013). Broad beans have a long tradition of cultivation in Old World agriculture, being among the most ancient plants in cultivation and among the easiest to grow They are still often grown as a cover crop to prevent erosion, because they can overwinter and because as a legume, they fix nitrogen in the soil. These commonly cultivated plants can be attacked by fungal diseases, such as rust (Uromyces viciae-fabae) and chocolate spot (Botrytis fabae). Acid soils occur widely in the highlands of Ethiopia where the rainfall intensity is high and the land has been under cultivation for many years These soils have PH values of less than 5.5, which result in low faba bean yields compared to other faba bean growing areas of the country. Objective of the study To find out the effects of farm yard manure and P fertilizer on the yield and yield components To determine the optimum rates of P fertilizer and FYM for faba bean production
