Rice Yield and Nitrogen Use Efficiency with Nano-Urea Treatments in India, 2022-2024

Field experiments from 2022 to 2024 in Varanasi and Guwahati assess the effects of nano-urea application on rice yield, economic returns, and nitrogen use efficiency. The dataset likely contains results from nine treatments in 2022 and seven treatments in 2023 and 2024, conducted in a Randomized Block Design replicated three times. It was authored by Panneerselvam Peramaiyan and is licensed under CC-BY-4.0.

Use Cases

• Compare rice yields based on conventional soil-applied nitrogen versus foliar nano-urea treatments.
• Analyze nitrogen savings achieved by combining reduced recommended doses with nano-urea sprays.
• Evaluate economic returns of different nitrogen application strategies in rice cultivation.
• Model the relationship between nitrogen application timing (panicle initiation, maximum tillering) and yield outcomes.

Strengths

• Data is derived from multi-year field experiments (2022–2024) replicated three times.
• Results are geographically specific, comparing outcomes in Varanasi and Guwahati.
• The study quantifies nitrogen savings (15–40 kg N ha⁻¹) and yield penalties (16–19%) with specific treatments.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The dataset is very small (35.3 KB), suggesting limited scope or summary-level data.
