Study of genetic diversity in bread wheat germplasm using nitrogen uptake and nitrogen use efficiency characteristics
In order to evaluate the traits related to nitrogen utilization and to identify the superior genotypes, 33 bread wheat landraces along three check cultivars of Chamran and Koohdasht (from Iran) and Gobustan (from the Republic of Azerbaijan) were studied in simple lattice statistical design with two replications under two treatments of non-usage and application of 200 kg/ha ammonium nitrate fert...
متن کاملNitrogen Dynamics and Fertilizer Use Efficiency in Rice Using the Nitrogen-15 Isotope Techniques
Nitrogen-15 ( N)-labeled biogas slurry (digested anaerobic organic residues (DAOR)) and chemical 15 fertilizer (CF) were applied to soil with low fertility cropped with rice. The N dilution method was used to 15 estimate the N uptake and recovery; potted soil was labeled with 1.0 atom % excess [ N] ammonium chloride 15 NH Cl. Certain select soil characteristics were also measured in soil amende...
متن کاملLong-Term Effects of Nitrogen Management Practices on Grain Yield, Nitrogen Uptake, and Efficiency in Irrigated Corn
Crop management strategies that improve Nitrogen Use Efficiency (NUE) increase profits while reducing the detrimental effects on the environment associated with fertilizer nitrogen (N) loss. Effective N management should include several critical factors that are very interrelated. A study was conducted at the Panhandle Research and Extension Center, Goodwell, OK to evaluate the effects of multi...
متن کاملThe 15N isotope to evaluate fertilizer nitrogen absorption efficiency by the coffee plant.
The use of the 15N label for agronomic research involving nitrogen (N) cycling and the fate of fertilizer-N is well established, however, in the case of long term experimentation with perennial crops like citrus, coffee and rubber tree, there are still shortcomings mainly due to large plant size, sampling procedures, detection levels and interferences on the system. This report tries to contrib...
