This study was conducted to select the best particle size of coco peat for cucumber nurseries as well as best particle ratio for optimum plant growth and development of cucumber. The experiment was carried out in International Foodstuff Company and Faculty of Agriculture, University of Ruhuna, Sri Lanka during 2015 to 2016. Under experiment one, three types of different particle sizes were used; namely fine (≤0.5mm) (T2), medium (3mm-0.5mm) (T3) and coarse (4mm<) (T4) with normal coco peat (T1) as treatments. Complete Randomized Design (CRD) used as experimental design with five replicates. Germination percentage, number of leaves per seedling, seedling height in frequent day intervals was taken as growth parameters. Analysis of variance procedure was applied to analyze the data at 5% probability level. The results revealed that medium size particle media (sieve size 0.5mm -3mm) of coco peat was the best particle size for cucumber nursery practice, when considered the physical and chemical properties of medium particles of coco peat. In the experiment of selecting of suitable particle ratio for cucumber plants; the compressed mixture of coco peat particles that contain 70% (w/w) unsieved coco peat, 20% (w/w) coarse particles and 10% (w/w) coconut husk chips (5 – 12mm) has given best results for growth performances compared to other treatments and cucumber grown in this mixture has shown maximum growth and yield performances.
