The effect of soil moisture content on soil temperature of Harumanis plant's growing area under greenhouse conditions

Abstract

The soil moisture and soil temperature factors are important to determine the quality of plant production because of the high market demand of Harumanis mango. By increasing the soil temperature, it affects the growth of plants and improves the fruit color. The relationship between soil moisture content and the soil temperature of Harumanis plant was evaluated. The research has been conducted in the semi-circular greenhouse and data was collected from 21 March to 8 April. The Watermark soil moisture sensor and temperature sensor were used to measure the soil moisture content and soil temperature. Both sensors were placed in the 15cm depth of soil. The sensors were then connected to the Arduino board to produce data through Data Cloud. The moisture content led the growth of Harumanis plant. Both moisture content and temperature were related to the evapotranspiration rate of the plant. However, there were large significance differences in the soil temperature and soil moisture parameters of each plant sample. The null hypothesis of the experiment which is the soil moisture will be is increased as the soil temperature increase was accepted as the p-values of the statistical analysis lower than 0.05. It has been suggested to vary the growth stage of Harumanis plant and apply to more plant sample to observe the variation flow of soil moisture and soil temperature.
