MATERIALS NEEDED TO GROW CROPS

The following materials are needed to grow crops:

1. Good seeds
2. Good stem cuttings
3. Fertilizer or manure

1. Good seeds

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.

2. Good stem cutting

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.

3. Fertilizer or manure

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.

4. Pest killing chemicals

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.
