Abstract

A pot experiment was conducted to elucidate the effects of nitrification inhibitor (NI) 3, 4-dimethylpyrazole phosphate (DMPP) on the nitrogen uptake, yield components, yield and grain protein content of spring wheat (Triticum aestivum L.) cv. Bahar during 2011 at ShahreKord University. A factorial experiment in randomized complete block design was carried out with two factors of type of N fertilizer (1- control with no added N fertilizer, 2-urea 3- ammonium sulphate nitrate (ASN) and 4- ASN plus DMPP) and soil type (10 soils) with three replications. The results indicated that application of nitrification inhibitor DMPP with ASN led to significant increase (P
