Abstract:
This study investigates the effect of organic and inorganic supplements on the reduction of ammonia (NH 3 ) volatilization, improvement in nitrogen use efficiency (NUE), and wheat yield. Methods A field experiment was conducted following a randomized block design with 10 treatments i.e ., T 1 -without nitrogen (control), T 2 -recommended dose of nitrogen (RDN), T 3 -(N-(n-butyl) thiophosphoric triamide) (NBPT @ 0.5% w/w of RDN), T 4 -hydroquinone (HQ @ 0.3% w/w of RDN), T 5 -calcium carbide (CaC 2 @ 1% w/w of RDN), T 6 -vesicular arbuscular mycorrhiza (VAM @ 10 kg ha −1 ), T 7 -(azotobacter @ 50 g kg −1 seeds), T 8 -(garlic powder @ 0.8% w/w of RDN), T 9 -(linseed oil @ 0.06% w/w of RDN), T 10 -(pongamia oil @ 0.06% w/w of RDN). Results The highest NH 3 volatilization losses were observed in T 2 at about 20.4 kg ha −1 per season. Significant reduction in NH 3 volatilization losses were observed in T 3 by 40% , T 4 by 27%, and T 8 by 17% when compared to the control treatment. Soil urease activity was found to be decreased in plots receiving amendments, T 3 , T 4 , and T 5 . The highest grain yield was observed in the T 7 treated plot with 5.09 t ha −1, and straw yield of 9.44 t ha −1 in T 4 . Conclusion The shifting towards organic amendments is a feasible option to reduce NH 3 volatilization from wheat cultivation and improves NUE.
