Effect of Foliar Application of Urea with N-(n-butyl) thiophosphoric triamide (NBPT) on the Yield of Cotton
نویسندگان
چکیده
Foliar fertilization with nitrogen (N) is used to supplement soil N application in order to meet the high N requirements of crops (Oosterhuis and Weir, 2010). Urea is the most common foliar N source in cotton, due to its relatively low toxicity, quick absorption, and low cost (Maples and Baker, 1993; McConnell et al., 1998; Oosterhuis and Bondada, 2001). However, in the literature reports of yield, increments with foliar urea application are not consistent. The general objective of this research was to determine the effect of addition of N-(n-butyl) thiophosphoric triamide (NBPT) to foliar urea to improve urea absorption and cotton yields.

Effect of Salinity on Cotton Nitrogen Uptake and Assimilation of Urea Applied with N-(n-Butyl) Thiophosphoric Triamide and Dicyandiaminde
Salinity is an abiotic stress factor that can cause significant crop yield losses. Nitrogen (N) is an essential plant element that is usually limited in most agricultural soils. Recently, incorporation of additives such as N-(n-butyl) Thiophosphoric triamide (NBPT) and Dicyandiaminde (DCD) into N fertilizers has been done with the purpose of increasing N use efficiency of crops. To our knowledg...

To limit nitrogen (N) losses from the soil, it has been suggested to provide urea to crops in conjunction with the urease inhibitor N-(n-butyl) thiophosphoric triamide (NBPT). However, recent studies reported that NBPT affects urea uptake and urease activity in plants. To shed light on these latter aspects, the effects of NBPT were studied analysing transcriptomic and metabolic changes occurrin...

A field experiment was designed to study the effects of nitrogen (N) source and urease inhibitor N-(nbutyl) thiophosphoric triamide (NBPT) or nitrification inhibitor dicyandiamide (DCD) on nitrous oxide (N2O) emission and N use efficiency (NUE) in a sandy loam soil. Six treatments including no N fertilizer (control), N fertilizer urea alone (U), urea plus NBPT (NBPT), urea plus DCD (DCD), urea ...
متن کاملInfluence of the novel urease inhibitor N-(n-butyl) thiophosphoric triamide on ruminant nitrogen metabolism: II. Ruminal nitrogen metabolism, diet digestibility, and nitrogen balance in lambs.
Three lamb metabolism experiments were conducted to investigate the effects of chronic administration of the novel urease inhibitor N (n-butyl) thiophosphoric triamide (NBPT) on ruminal N metabolism, fermentation, and N balance. In Exp. 1, ruminally cannulated wethers (n = 28; 45.0 +/- .9 kg) were administered one of seven doses of NBPT (0 [control], .125, .25, .5, 1, 2, or 4 g of NBPT daily) a...
