This study aimed to determine supplemental substrates that can be mixed with soil growing melon plants in an isolated bed cultureand also substrate to soil ratio in order to provide a favorable soil condition in the culture for producing premium melon fruits in year-round producing system. Results of this study were practically used for melon growers.
1. When the soil was mixed with perlite and straw in the isolated bed culture, the total root growth increased more than that of control plants. It may be associated with that the perlite substrate improves aeration pores in the soil.
2. The thicker root diameter was observed when the straw was mixed with a 20 L volume-soil compared to the perlite substrate.
3. Suitable irrigation system for the isolated bed culture can be set up on the basis of soil moisture tension. The recommendable point of irrigation is when soil water potential drops below-25kPa in terms
of obtaining goodplant growth, fruit weight and soluble solid concentration.
4. The good performance of plant growth was observed in the order of-15kPa > control >-20kPa >-25kPa > timer >-30kPa treatment, while the fruit weight was in the order of control > timer >-25kPa >-20kPa >-15kPa >-30kPa treatment. The soluble solid concentration was negatively correlated with irrigated water amount.
5. A soil medium inserter developed in this study is attachable to a small-sized manager. It consists of an inhaler for inhaling soil medium and a conveyor for conveying the soil medium to the bed system. Unevenly dropped soil medium by the inserter can be adjusted to left and right direction depending on the position of the isolated bed.
