| The effect of the particle size of perlite and irrigation amount on the growth, root activity and mineral competition of tomato was investigated in a recycling system. The particle sizes used were small (SPP, ©ªl¡2 mm), medium (MPP, ©ª2¡3 mm), (LPP. ©ª4¡5 mm). Plant height, fresh weight and dry weight of tomato at the earlier growth stage were good at 3.0 L/day in MPP and LPP, but these were not significantly affected by irrigation amount in MPP, Fruit number, weight and yield increased at 1.5 L/day in SPP and 3.0 L/day at MPP or LPP, Deformed fruits tended to increase at higher irrigation amounts regardless of particle size. Root activity increased with increasing particle size with higher irrigation amount during early stage after transplanting, but remarkably decreased at 3.0 L/day in SPP as compared with the others at 100 days. Mineral contents of plants after harvest were higher at MPP and LPP than SPP, but were highest at 3.0 L/day in LPP. In conclusion, it was regarded that tomato growth in a recycling system was optimal at MPP or LPP with irrigation amount of B.0 L/day. |
