Planting Density of Red Pitaya (Hylocereus Polyrhizus) to Achieve Optimum Yield Under Malaysia Weather Condition

Then Kek Hoe
Red Pitaya (Hylocereus polyrhizus) was commercially been planted in Malaysia in the early 2000’s. It grows well under local weather condition and started to fruit within a year after planting. Red pitaya received high demand from domestic market due to its high nutrition value. A study was conducted to improve the yield productivity of red pitaya planting by introduced two intensive planting densities at 1,815 trellis plants/ha (3.0m x 1.8m) and 1, 556 trellis plants/ha (3.0m x 2.1m) as compared with the common planting density at 1,361 trellis plants/ha (3.0m x 2.4m). This study was laid out in Randomised Complete Block Design in three replications with 30 recorded trellises per density. This study was conducted for four years. The cumulative yield over four years of harvesting showed that the highest planting density at 1,815 trellis plants/ha produced 48.7 t/ha (170, 066 fruits/ha), followed by 41.8 t/ha (152, 177 fruits/ha) and 38.2 t/ha (133, 786 fruits/ha) with the planting density of 1, 556 trellis plants/ha and 1, 361 trellis plants/ha, respectively. The average fruit weight and fruit number per trellis among the planting densities were almost similar and ranged from 276-293 g/fruit and 94-98 fruits per trellis, respectively. The high planting density at 1, 815 trellis plants/ha did not affect the fruit number and fruit weight, but increased the total fruit yield of red pitaya by 26.5%. Therefore, the high planting densities at 1,815 trellis plants/ha was recommended for red pitaya planting under Malaysia weather condition to achieve the optimum yield productivity
