Cassava growing conditions：

Cassava is generally grown not in areas where the crop grows best, but in those areas where it grows better than other competing crops.

Cassava grows well in tropical and subtropical areas up to about 250 N and S, with 1000-2000 mm annual rainfall, and with 4-6 months of dry season.

Cassava grows best in well-drained sandy loam to clay loam soils, with pH 4.5-7.5 and with lowintermediate levels of OM, P and K.

The best times to plant and harvest:

? Plant as early as possible at the beginning of the wet season, and harvest in the middle of the dry season (at about 10-11 months), or

? Plant towards the end of the wet season and harvest in the middle of the next dry season (at about 16 months)

? In subtropical climates, plant in the very early spring and harvest in early to late winter, or plant at any time and harvest after at least 12 months, but not in the hot and raining time of the year
