Abstract
Two filed experiments were conducted during 2015 and 2016 seasons at the Research Farm of El-Sirw Agricultural Research Station, Damietta Governorate, Egypt. The experiments were performed to study the response of Giza179 rice cultivar to eight nitrogen sources Viz; ammonium sulfate (AS), ammonium nitrate (AN), urea (U), Di-ammonium phosphate (DAP), mono ammonium phosphate(MAP), calcium ammonium nitrate (CAN), and calcium nitrate (CN) and potassium nitrate (KN) under saline sodic soil conditions. The experimental soil was clay with salinity level 7.5 and 7.3 dSm-1 and sodicity (ESP) level 41and 40% dSm-1 in 2015 and 2016 seasons, respectively. The experiment was performed in randomized complete block design and repeated four times. The main obtained results could be summarized as follows; The nitrogen source had significant differences on nutrients leaf contents (NPK), rice growth (leaf area index, dry mater production and chlorophyll content), yield attributes and grain yield in both seasons. Ammonium sulphate showed good and better regarding nitrogen leaf content, while, CAN and KN recorded the highest values of K leaf content. However, DAP and MAP recorded the highest values of P leaf content in both seasons. Ammonium sulphate recorded the highest values of studied growth traits while, the sources contain nitrate (AN, CAN, CN and KN) had the lowest values. The DAP and MAP were comparable regarding their favorable effect on rice growth occupying the second position after ammonium sulphate. The ammonium sulphate had high yield component giving high grain yield followed by DAP and then MAP. Generally, urea or ammonium nitrate as well as any sources contains nitrate is not efficient to apply it for rice under the same saline sodic soil conditions.
