A field experiment was carried out in Dhi Qar Governorate, Al-Fadhliya region, for season of 2018-2019. Chemical compounds DMPP, DCD, and ATS as well as aqueous extracts of capers seeds and palm bast, were added to inhibiting the nitrification in the soil, and some of the growth characteristics of the wheat. Three of nitrogen level were added as urea (46% N) fertilizer (100, 150 and 200 kg N per ha). Aqueous extracts of plants were added to the urea fertilizer at a concentration of 100 ml for each kg of fertilizer. The experiment designed used RCBD with three replications. Wheat seeds were sown at 11/15/2018. Soil samples were Collecting from the soil (0-30) cm during the growing season after (10, 20, 40 and 60) days after the fertilization. The amount of ammonium, nitrate and nitrite, were estimated. The results showed that the fertilizer level 150 kg N ha −1 with all extracts and chemical compound treatments were exceeded compared with 200 kg N ha −1 without treatments.
