EFFICIENCY OF NITROGEN FERTILIZER IN WHEAT AS INFLUENCED BY DIFFERENT NITRIFICATION INHIBITORS

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