Résumé
A field experiment was conducted to assess the role of integrated use of farm yard manure (FYM) and mineral fertilizers on soil fertility parameters and grain yield and yield components of wheat in the highlands of northeastern Ethiopia. The soil chemical properties were affected by both application of FYM alone and integrated with mineral fertilizers. Increases in soil fertility parameters were observed with increased levels of FYM application. The integrated application of FYM with mineral fertilizers significantly increased wheat yield and yield components. The addition of 5 and 10 ton ha-1 FYM gave yield advantages of 15.7 and 16.4% over the non-manured plots, respectively. The highest grain yield of wheat (2253.4 kg ha-1 ) was obtained by applying 5 ton ha-1 FYM combined with 0/10 Kg ha-1 N/P. As a conclusion, the application of FYM at 5 and 10 ton ha-1 with 50% the locally recommended mineral fertilizer rates had a positive effect on soil fertility parameters and wheat yield and yield components.
