Pepper Farm
The purpose of this research is to study the effects of climate and soil quality on biochemical constituents of Trang pepper and to compare the biochemical constituents of Trang pepper in Palian and Nayong districts, Trang. The researcher collected data by visiting study area of Mr. Charoon Siem Mai pepper plantation, Suso sub-district, Palian district and Miss Supinya Panrung pepper plantation, Lamor sub-district, Nayong district, Trang Province by collecting weather data and soil samples using GLOBE Protocol to analyze quality and correlation with piperine content percentage obtained from HPLC Chromatogram. According to studying results, the weather data of Palian District had an average rainfall between September 2022 to January 2023, more than Nayong District but the soil quality data of Palian District had lower soil moisture than Na Yong District because the soil texture of Palian District is clay loam. Sandy silty soil, which can drain well, therefore has lower moisture content in the soil than Na Yong District, which has a silty clay soil texture that can retain moisture in the soil better. It was found that Nayong district had higher soil nutrient (NPK) levels than Palian district. Therefore, the amount of rainfall stored in the form of moisture in the soil and the nutrient level in the soil resulted in the percentage of piperine in the two pepper plantations, There was a statistically significant difference. Nayong District had the percentage of piperine 3.100.20%, Palian District therefore contains the percentage of piperine 2.770.37% Nayong District had higher soil moisture content and soil mineral content than Palian District. As a result, the piperine content of Na Yong District was higher than that of Palian District. From the characteristics of soil texture and soil moisture above. The soil of the Nayong pepper garden is suitable for the growth of Trang pepper.

I found your research report very well written, and your video presentation was also very well done! The topic of your research, looking at the impact of weather and soil quality on the quality of the special pepper that is grown in your area is perfect for this year's focus on the interconnections between Earth's systems. If you would like to include satellite data in your next research project, the NASA satellite that I support is called the Global Precipitation Measurement mission, or GPM for short. We have measured precipitation using this amazing satellite technology since 1997, and the data is freely available. You can find out how to upload and analyze seasonal precipitation data at this site here. https://gpm.nasa.gov/education/current-activities/The-GLOBE-Program.  It would be really interesting to see you integrarte satellite data as well as ground-based data into this study. Great work!
