| Abstract | ||
| Farmyard manure (FYM) is a vital organic resource and their extensively used in soil management for sustainable agriculture. Field experiment was carried out during two successive growth seasons of 2014 and 2015 at the Experimental Farm of Department of Soils and Water, Faculty of Agricultural, AL-Azhar University, Assiut governorate to examine the effect of farmyard manure and level of applied phosphatic fertilizeron phosphorus availability and corn (Zea mays) yield. The experiment was designed as a randomized complete block design in split plots with four replications. Results showed that the farmyard manure treatments (0 and 30 m3/fed.) were assigned to the main plots and levels of superphosphate (100, 200 and 300 kg /fed.) were in the sub-plots. The application of FYM to this soil increased significantly available phosphorus throughout two growth seasons. Also addition 30 m3 FYM increased the grain yield of corn from 12.59 to 17.19 ardab/fed. in first season and from 12.22 to 19.61 ardab/fed in the second season. Application of 30 m3 FYM combined with 200 kg/fed superphosphate resulted of increasing (GY) from 11.87 to 18.23 ardab/fed. at first season and from 11.82 to 21.43 ardab/fed. in second season.We Application of 200 kg superphosphate /fed combined with 30 m3farmyard manure to the soil led to positive effect of this treatment on grain yield of corn. | ||
