Red pitaya (Hylocereus polyrhizus) is a popular minor fruit crop in Malaysia. It has high demand from domestic market due to its nutrition value and phytonutrient content such as betacyanins, flavonoids and phenolic acids. It started to grow in Malaysia since early of 2000’s and the total planted area in year 2018 was estimated about 680 hectares. An observation was conducted to study the flowering pattern and fruit production of red pitaya under Malaysian growing condition. Total of forty-five trellises of red pitaya plants at the age of two years after fruiting from three different blocks were used to monitor the flowering batches, flower intensity, fruit production and yield for the period of two years. The recorded data indicated that red pitaya flowering minimum one batch per month to maximum three batches per month. The average flower intensity was 3.5 flowers per trellis per batch, the maximum flower numbers at peak season was 12.7 flowers per trellis and only 0.3 flowers per trellis at the low season. The average monthly flowering intensity was 6.9 flowers per trellis with the annum flowers production of 82.6 flowers per trellis. Meanwhile, the fruiting pattern of red pitaya showed to produce 4.4 fruits per trellis per month with the total annum fruit production of 52.9 fruits per trellis. The average yield of red pitaya was 20.1 tonnes per hectare per annum with the monthly yield of 1.7 tonnes per hectare. The peak production season of red pitaya was from April to September with the average monthly yield of 2.0-3.0 tonnes per hectare as compared to low season from October to January only recorded less than 1 tonnes per hectare.
