| This study was conducted to identify the effects of irrigation amount to produce high quality melon fruit in fertigation culture. Irrigation amount of during fruit harvesting period was doubled at the low irrigation point ($(-45{sim}50;kPa$) treatment as 115 mm as than that of the high irrigation point ($-20{sim}25;kPa$) treatment. The plant growth rates such as stem length, leaf weight and plant height were a little diminished at the low irrigation point ($-45{sim}50;kPa$) than those of the other treatments. Internode length was however not affected by irrigation amount. Fruit weight was lighter at the low irrigation point ($-45{sim}50;kPa$) than that of at the high irrigation point and fruit height was shorter, but fruit diameter was not affected by irrigation amount. Fruit soluble solid was $0.9^{circ}Bx$ higher at the low irrigation point ($-45{sim}50;kPa$) than at the high irrigation point ($-20{sim}25;kPa$) and net index was higher. Total marketable yield was highest by 3,937 kg/10a at the high irrigation point ($-20{sim}25;kPa$), but the excellent marketable yield was highest by 2,531 kg/10a at the low irrigation point ($-45{sim}50;kPa$). Inorganic contents of the soil N, K, Ca and Mg were not affected by irrigation amount. It was therefore thought that optimum irrigation point to produce high quality melon fruit by fertigation culture was $-45{sim}50;kPa$ at ripening stage. |
