Abstract
A field experiment was conducted at EL-Gemmeiza Experiments Station using wheat plant (Triticm aestivum L.) (v.gemmeiza 9) during two successive seasons (2011/2012) and (2012/2013) to evaluate the use efficiency of urea fertilizer mixed with humic acid (HA). The treatments as follows: T1) Control without addition, T2) Urea at 75 kg N fed-1+ Humic Acid (2%), T3) Urea at 50 kg N fed-1 + Humic Acid (2%), T4) Urea at 75 kg N fed-1and T5) Urea at 50 kg N fed-1. Results are summarized as follows: Wheat yield (grain and straw) show a significant response to nitrogen application. The best treatment was urea mixed with humic acid compared with using urea alone. The highest value of yield was recorded with 75 kg N. fed-1 mixed with HA, followed by 50 kg N fed-1 with HA. These results proved that loss of nitrogen on form of ammonia is reduced when urea is mixed with an appropriate amount of HA. Therefore, using the same amount of nitrogen fertilizer mixed with humic acid ensure a substantial increase in wheat yield.
