Discussion

Field experiment shows improved grain yield and protein content in wheat with higher nitrogen and phosphorus levels in semi-arid regions.

The highest grain yield of 4650 kg/ha was achieved with 180 kg N and 40 kg P₂O₅ per hectare, highlighting optimal nutrient levels.
Significant improvements in growth, yield attributes, and protein content were observed with adequate nitrogen and phosphorus application.
The maximum net return of ₹88,348/ha indicates the economic feasibility of balanced fertilization in wheat production.
Results suggest that nitrogen and phosphorus are essential for enhancing soil fertility and productivity in semi-arid conditions.

Parmar et al. (2025) studied this question.
