Abstract

Response of two sorghum cultivars namely Izra-7 and Razini to manure and phosphate fertilizer was studied in factorial arrangement in two separate field experiments on calcareous soil at Jordan University of Science and Technology campus (JUST). Increased yields of both cultivars was obtained by integrated application of manure and P, which was a consequence of high harvest index, grain number and panicle length coupled with more total dry matter production. Grain and biological yield of Izra-7 responded to lowest combinations of manure and fertilizer P when compared to Razini that responded significantly up to the highest combination rates. Regression analysis showed linear effects of both manure and P on grain and biological yields. Increased residual P content of the soil after sorghum harvest was evidenced with much more contribution from manure compared to P applied. Overall, manure application at highest rate increased grain yield and other yield component; however, its effects were more pronounced when applied with mineral P. The benefit of integrating manure with Phosphate fertilizer was evident.
