Benth] Management and S orghum [Sorghum bicolor (L.) Moench ] Growth and Yield in Pawe District, Northwestern Ethiopia Sorghum production in Pawe District is often constrained by low soil fertility resulting from continuous cropping with minimum or no input which in turn encourages Striga infestation. Field experiment was conducted during the 2010 cropping season to investigate the effects of Leucaena leaf biomass incorporation and NP fertilizer application on sorghum growth and Striga control. Two levels of Leucaena leaf biomass (2.5 and 5 t ha -1 ) were applied with 50% recommended dose of urea (RDU) with or without 50% recommended dose of diammonium phosphate (DAP). The experiment included a standard treatment of 100% recommended dose of fertilizer (RDF i.e. 100 kg urea + 100 kg DAP) and farmers’ practice of growing sorghum with...

To combat the problem different Soil and Water Conservation (SWC) measures were introduced in the country. This research was conducted in the Harowerke micro-watershed, West Showa Zone, Oromia Regional State to assess effect of conservation measures on selected soil properties. Graded stone bunds are one of the conservation measures in study area. It included a comparison between farm plots with six-year graded stone bund and non conserved ones. A total of 48 surface soil samples were collected and analyzed for soil bulk density (BD), moisture content (MC), organic matter (OM), total nitrogen (TN), hydrogen ion concentration (pH) and cation exchange capacity (CEC) of soil. Results showed that soil BD and soil MC were significantly (p≤0.05) affected by the soil conservation measures and slope gradients. Soil OM, TN, and CEC also showed...
