The experimental layout was conducted within an area of 10 m2and divided into 5 plots, the block-size per plot was 1.2 × 1.6 m. The results showed that the bulb’sdiameter was greater than 6 cm which was suitable for the floweringThe rate of leaf development corresponded to the growth process of plants and the average leaf lengths ranged f-rom 59.40 to 74.56 cm. The average plant heights of Hippeastrum equestre Herb ranged f-rom 45 to 50 cm. In addition, the study carried out the dryingHippeastrum equestre Herb’s bulbsin the the various period of 10, 15, 20, 25, 30 days to observed the flowering development. The results investigated that the driedbulbs had a significant effect on flowering time and and flower development which found the longer the drying period of bulbs and thus produced flowers soonerThe thickness, length, and width of petals of Hippeastrum equestre Herb ranged f-rom 0.079 to 0.084 cm, 10.55 to 11.62 cm and 6.48 to 7.12 cm, respectivelyKeywords Hippeastrum equestre Herb floweringgrowth, sandy soil
