| Abstract | ||||
| Two field experiments were conducted in 2015 and 2016 growing seasons at the farm of Agricultural Research Station, Sakha, Kafrelsheikh, Egypt, consisted of three cultivars(Sakha106, Giza179 and Egyptian hybrid rice one) as well as seven nitrogen (N) fertilizer treatments were added at the rate of 165 kg N/ha. Anhydrous ammonia (82% N) was injected directly into the dry soil at the depth of 20 cm before plant, while, urea (46% N) was applied according to the recommended of RRTC. Results revealed that application of nitrogen at 165 kg N/ha as anhydrous ammonia recorded the highest chlorophyll content, LAI, dry matter/m2, plant height (cm), no. of tiller/m2, panicle number/m2, panicle weight(g), panicle length (cm) and filled grains resulted in a highest grain yield. Also, economic analysis was done. Data shows that the highest profit was recorded when full dose of Anhydrous Ammonia was applied with all varieties. | ||||
