Area of Science:

  • Agronomy
  • Plant Science
  • Crop Physiology

Background:

  • Nitrogen is a crucial nutrient for bread wheat (Triticum aestivum L.) growth and yield.
  • Optimizing nitrogen application is key to enhancing crop productivity and grain quality.

Purpose of the Study:

  • To evaluate the impact of varying nitrogen levels on four distinct bread wheat varieties.
  • To identify optimal nitrogen rates and superior wheat varieties for improved yield and protein content.

Main Methods:

  • A split-plot design experiment was conducted with four replications.
  • Four bread wheat varieties (Inqilab-91, Daman-98, Dera-98, Punjab-96) were tested.
  • Nitrogen was applied at rates of 0, 50, 100, 150, and 200 kg/ha.

Main Results:

Related Experiment Videos

  • Nitrogen levels significantly affected plant height, plant population, grain yield, and protein content.
  • The highest plant height, yield, and protein content were recorded at 200 kg N/ha.
  • Daman-98 exhibited the greatest plant height, biological yield, and grain yield, while Inqilab-91 had the highest grain protein.

Conclusions:

  • Applying 200 kg N/ha is optimal for maximizing bread wheat yield and protein content.
  • Daman-98 and Inqilab-91 demonstrated promising traits for high yield and protein, respectively.
  • Nitrogen management strategies should consider variety-specific responses for enhanced crop production.
