Some factors to consider when producing black peppercorn include temperature, humidity, rainfall, light and wind, altitude and soil.
- Temperature and humidity: Pepper plants can withstand the lowest temperature of 10 degrees, the highest 40 degrees, develop well at an air temperature of 20-32 degrees, relative humidity over 70%, and soil temperature. At a depth of 30 cm about 25-28 degrees.
- Rainfall: Pepper trees need high rainfall, evenly distributed in the rainy season but must have a clear dry season, the total annual rainfall is suitable for pepper in the range of 1,500-2,500 mm.
- Light and wind: Pepper trees love the scattered light and like the calm environment.
- Altitude: Pepper trees can be planted to a height of 1,200 m above sea level, but grow well on high land in the plains, altitudes below 600 m.
- Soil: Pepper plants grow well on fertile soil, rich in organic, porous, well-drained; Lowest soil pH 4.5; best in the range of 5.5-6.5; cultivated soil layer above 70 cm, best over 1 m; land with a slope of less than 10%, preferably 3-5%; The water table is more than 2 meters deep in the rainy season.
