<p>Effects of different rates of nano-NPK fertilization (NF-NPK) and salicylic acid (SA) a

Experimental data from Zhenhao Guan on the effects of nano-NPK fertilizer and salicylic acid application on tomato cultivation. The dataset includes metrics for energy input, output, efficiency, productivity, net energy, greenhouse gas emissions, and greenhouse gas ratio across the 2022 and 2023 growing seasons. Data are presented as mean values with standard error in a 9.5 KB XLS file.

Use Cases

• Modeling the relationship between fertilizer application rates and energy-use efficiency in tomato cultivation.
• Assessing the environmental impact of different fertilization strategies based on greenhouse gas emission metrics.
• Comparing the effects of nano-fertilizers versus traditional methods on net energy and productivity.
• Analyzing seasonal variability in energy and GHG performance for agricultural practices.

Strengths

• Data spans two consecutive growing seasons (2022 and 2023), allowing for seasonal comparison.
• Includes multiple calculated sustainability metrics such as energy-use efficiency, net energy, and greenhouse gas ratio.
• Data points are presented as mean values with associated standard error, indicating statistical processing.
• Available under a permissive CC-BY-4.0 license for reuse.

Limitations

• Row count is unknown, which may limit suitability assessment for large-scale modeling.
• Column-level documentation is absent; field semantics must be inferred after download.
• The dataset is very small (9.5 KB), suggesting a limited scope or number of observations.
