a) (i) (ii) Yield levels from research stations for conventional varieties range between 2.56 (under severe moisture stress); 5.93 under moderate stress and 11.53 tonnes/ha under optimum conditions.
b) (i) (ii) Yield levels from farmers’ fields for conventional varieties range from 1.14 to 5.79 tonnes/ha depending on the level of management and stresses experienced by the maize crop. Genetically modified hybrids with the drought trait have not yet been deployed in smallholder farmer’s fields.
