MATERIALS NEEDED TO GROW CROPS
The following materials are needed to grow crops:
Seeds to be grown must be viable (living healthy seeds). They must not be seeds that are affected by diseases. Examples are good seeds of beans, melon and maize grains.
Good stem cuttings are used in growing cassava and some tree crops. The cuttings must not be affected by diseases and must be clean and healthy looking.
Fertilizers or manure supply mineral nutrients that serve as food to crop plants. They are usually added to the soil to make our crops grow well and healthy.
Chemicals called insecticides can be spayed on the plants to kill insects. Baits are used for rodents (rats, rabbit) and scare crow for birds. Chemicals called rodenticides can be used to kill rodents.
