Wheat Yield and Protein Response to Seeding Rates in Southern Egypt

Field experiment data compares grain yield, yield components, and protein concentration for two wheat cultivars under four seeding rates. The study was conducted over two years in Qena, Upper Egypt, using a randomized complete block design with three replications. Author Iqbal Zahid published the findings to determine optimal seeding rates for wheat productivity in sandy loam soils.

Use Cases

• Model grain_yield as a function of seeding_rate and cultivar using regression analysis.
• Analyze the interaction effect between cultivar and seeding_rate on harvest_index and straw_yield.
• Compare grain_protein_concentration between the bread wheat Giza 168 and durum wheat Sohag 3 cultivars.
• Fit crop production functions for yield_components based on seeding rates to extrapolate to other regions.

Strengths

• Experimental design includes three replications for statistical reliability.
• Data covers two distinct wheat cultivars and four seeding rates across two growing seasons.

Limitations

• Geographic scope is limited to a single location (Qena, Upper Egypt), reducing generalizability.
• Sample size is constrained by experimental plots, with unknown total row count for measured variables.
