چکیده

Foliar application of nitrogen (N) is used to supplement soil N application in order to meet high N requirements of crops (Oosterhuis, 1999). 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 and it is not clear whether the occurrence of phytotoxicity from foliar urea application is caused by toxic accumulation of urea or ammonia.

Effect of Foliar Application of Urea with N-(n-butyl) thiophosphoric triamide (NBPT) on the Yield of Cotton

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).

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...

Effects of Temperature and Application of Urea with N-butyl Thiophosphoric Triamide and Dicyandiaminde on Cotton

Crops are usually known to have low N use efficiency, recovering only 30-35% of the N supplied (Constable and Rochester, 1988; Daberkow et al., 2000). Different practices have been recommended to increase crop N-use efficiency and much attention has been focused on the use of urease and/or nitrification inhibitors to decrease losses of N by volatilization and leaching. Cotton (Gossypium hirsutu...
