Lost Crops of Africa: Volume I, Grains
High Temperature
Finger millet thrives under hot conditions. It can grow where temperatures are as high as 35°C.14 In Uganda, the crop grows best where the average maximum temperature exceeds 27°C and the average minimum does not fall below 18°C.15
Soil Type
The crop is grown on a variety of soils. It is frequently produced on reddish-brown lateritic soils with good drainage but reasonable water-holding capacity. It can tolerate some waterlogging.16 It seems to have more ability to utilize rock phosphate than other cereals do.17

In recent trials of nine cereal species subjected to waterlogging from seedling to heading, finger millet was the most resistant, except for rice. It resisted waterlogging much better than maize. (Kono et al., 1988.)

In pot experiments, the rock phosphate mobilizing capacity increased in the order maize: pearl millet: finger millet. (Flack et al., 1987.)
