“…Current environmental concerns lead to the search for strategies to maximize the efficiency of nitrogen (N) fertilization in maize crop (Kramberger et al, 2009;Setiyono et al, 2011;Ciampitti and Vyn, 2014), because under Mediterranean conditions irrigated maize crops are often associated with the risk of nitrate pollution (Salmerón et al, 2011). The excess N application is a threat to the environment (Raza et al, 2019) and potentially also to our health (Sandhu et al, 2019).…”

“…In general, optimal nitrogen applications are essential for improving the nitrogen use efficiency (NUE) in the field (Wang et al, 2018;Raza et al, 2019aRaza et al, , 2019bNoulas et al, 2018). For example, Hartmann et al (2015) found that a higher recovery efficiency (the components of NUE) could be achieved when the N supply was reduced by 100 kg ha −1 from the standard farmers' practice without reducing the crop yield of summer-corn or winter-wheat, while reducing the residual soil mineral N. Nitrate distributions and NUE in intercropping ecosystems were reported in several previous studies (e.g., Ding et al, 2014;Sun et al, 2018;Zhao et al, 2019).…”

“…Maximum increase in spike length for wheat was observed for urea + DCD treatment. Raza et al (2019) reported that urea and urea + ATC application enhanced the spike length as well compared to control. The application of urea with DCD increased spike length in wheat compared to urea alone.…”

“…The application of urea with DCD increased spike length in wheat compared to urea alone. The authors suggested that the reduction in nitrogen losses due to the inhibition of nitrification by DCD may have contributed to the increase in spike length (Raza et al 2019). He et al (2018) also found that the application of urea with DCD had no significant effect on spike length in wheat.…”

The nitrification inhibitors are very important in plant nutrition because they prevent the losses and volatilization of nitrogen fertilizers from the soil surface. In this study, the coated nitrogen fertilizers with Dicyandiamide and 4-amino-l,2,4-triazole inhibitors were used and the results from these coated fertilizers was compared with their respective control treatments (without coating). Two wheat varieties Ujala16 and NA1530 was evaluated. The field experiment was arranged in randomized complete block design under split plot arrangement with three replications. Nitrogen treatments which are urea, urea+4-amino-l,2,4-triazole (ATC) inhibitors and urea+ Dicyandiamide (DCD) inhibitor as sub factor and varieties (Ujala16 and NA1530) were maintained as main factor. A control without urea application and a positive control of urea application without coating were maintained for comparison. Data were collected for different agronomic and biochemical related parameters. The data collected was analyzed by Fisher’s analysis of variance technique to determine the variability among the data and mean values of treatments were compared by using least significant difference (LSD) test at 5% probability level. The results showed that nitrification inhibitors had increasing impact on different physiological and biochemical parameters related N treatments including (chl a, chl b, carotenoids, and catalase activity) as well as positive impact on total soluble protein. NI also contributes positively by increasing different yield and yield contributing parameters including (number of tiller per plant, grain weight per spike, 1000 grain weight, plant height, grain yield and harvest index). There is also increasing impact related to varieties with the application of NI on different biochemical parameters including (chl b, chl a+b, carotenoids, proteins, Pod and catalase activity). Different yield and yield components also enhance positively in varieties which are, (number of grains/spike, total plant height, grain yield and biological yield). Hence NI plays a positive role in increasing different physiological and biochemical parameters as well as yield and yield components and ultimately wheat yield also increase.
