Abstract

The standard method for seed moisture determination is the low-constant temperature oven method. Rapid determination of seed moisture content can use a moisture meter, but we must calibrate and validate first with the standard method. LDS-1G Grain Moisture Meter is recommended for only twenty types of samples (seed or seed meal). Seven tropical vegetable seeds (chickpeas, chili, cucumber, kangkong, long beans, tomatoes, and spinach) were used to validate the LDS-1G Grain Moisture Meter compared to the oven method. The paired t-test result showed no significant difference between the Oven Method and LDS-1G Grain Moisture Meter on moisture content measurement of cucumber, kangkong, long beans, and tomato. The LDS-1G Grain Moisture Meter could predict seed moisture content significantly differently with the chickpea, chili, and spinach seeds oven method. The recommended codes when measuring the moisture content of tropical vegetable seeds using LSD-1G Grain moisture meter, are as follows: cucumber on P6 and P7 codes- kangkong on codes P5, P6, P10, P11, and P12- long beans on codes P6, P7, P10, P11, and P12- and tomatoes on codes P3, P6, P10, P11, and P12.
