Abstract
The combination of urea or ammonium sulphate (A\so4) with farmyard manure (FYM) as well as using anyone of them alone as a source of nitrogen for rice cultivation was studied at Rice Research and Training Center (RRTC), Sakha, Kafr EL-Sheikh Governorate, Egypt during 2005 and 2006 seasons. The results revealed that, grain and straw yields and yield components significantly increased with the application of nitrogen sources in comparison to unfertilized check. There were no significant differences between urea and ammonium sulphate on the above mentioned characters. The ability of FYM alone to provide nitrogen is insufficient because of its lower N-content and higher C\N ratio. Generally, the combination of urea or ammonium sulphate with FYM in 75:25 ratio and full dose of mineral fertilizer either urea or ammonium sulphate gave the same effect of yield and yield components of rice. Under this study we can recommended that application of urea or ammonium sulphate or its combination with FYM in ratio 75:25 gave the best grain yield of rice.
