Abstract
A two-year study was conducted at Sakha Research station, Agricultural Research Center (ARC), Kafr El-Shiekh governorate, Egypt during 2013/2014 and 2014/2015 to decrease mineral nitrogen (N) inputs of wheat crop. This study included two experiments each one contained 9 treatments, which were combinations of three cropping sequences (summer crop/Egyptian clover "fahl''/wheat, summer crop/fodder maize/wheat and summer crop/fallow/wheat) and three mineral N fertilizer rates (80 kg N/fad, 60 kg N/fad + ascobien and 40 kg N/fad + ascobien). A split plot design with three replications was used and combined analysis was done for the two experiments in each season. The results showed that there were clearly insignificant differences between rice and maize as a preceded summer crop on grain yield of wheat plants. The cropping sequence (maize or rice /Egyptian clover "fahl''/wheat) increased significantly all the studied wheat traits compared with the other copping systems in the two seasons. There were insignificant differences between application of 80 kg N/fad and 60 kg N/fad + ascobien for grain yield/fad in the two seasons. The optimum grain yield/fad was obtained by growing Egyptian clover "fahl'' during transition period between preceded maize or rice in the summer season and wheat that fertilized by 60 kg N/fad + ascobien in the winter season.
