To study the effect of nitrogen fertilizer sources and foliar spray of organic acids on rice crop, In this regard, this test was performed in 2010 and 2011 years at El- Gemmeiza Agricultural Research Station, El-Gharbia Governorate located at lat. 30.47, long 31.00 and 14.80 m above the mean sea; the used design was split plot randomized complete block with 3replications. Main plots, two nitrogen fertilizer sources: anhydrous ammonia & urea while subplots, were treated with foliar application of humic and / or fulvic acid resulting 4 treatments including: controls (without foliar spray), humic, fulvic and humic +fulvic acids were considered.
