Rapid Soil Checker and Smart Soil and Rain Sensor are designed to measure P and K levels in real time; however, their relationship with vegetable crop growth has not yet been studied. This research aimed to assess the correlation between the readings from Rapid Soil Checker and Smart Soil and Rain Sensor for available P and K and the growth of several types of vegetable crops. Nutrient saturation was conducted from January to February 2024 at the Cikarawang Experimental Field, Department of Agronomy and Horticulture, Faculty of Agriculture, IPB University. The correlation study was carried out from March to May 2024 in the Sukamantri greenhouse, Faculty of Agriculture, IPB University. The research consisted of four experiments: correlation tests between multi-sensor readings and dry plant weight of shallot, Chinese mustard (caisim), tomato, and chili pepper, each under five nutrient saturation levels: very low (0X), low (1/4X), medium (1/2X), high (3/4X), and very high (X). The results showed that the correlation between nutrient readings from both sensors and plant dry weight was very weak. In contrast, the Mehlich-1 laboratory method demonstrated a strong positive correlation
