MATERIALS NEEDED FOR GROWING CROPS
The following are needed for growing crops
- Good seeds;
- Good stem cuttings;
- Fertilizer or manure;
- Weed and pest killing chemicals.
Use seed that have the following:
- The seeds should be healthy.
- They must not be infected by disease.
- The seeds should be fresh.
- The seeds should not have holes or damage on them.
TYPE OF SEED
- Maize seeds
- Melon seeds
- Bean seeds
GOOD STEM CUTTING
Some plants or tress crops stem can be plated like cassava.
Before planting a stem ensure the following are in place:
- The cutting must be infected by diseases.
- The stem must be clean
- The stem must be healthy
FERTILIZER OR MANURE
They gives the soil nutrients and it is pass to the plant for effective growth.
Types of fertilizer
- Inorganic or synthetic fertilizer;
- Organic fertilizer or manure.
PESTS OR WEED KILLING CHEMICALS
Chemical such as gram Oxone, prim extra and atrazine can be used to kill weeds by spraying it on the weed to kill the weed or spraying it on the ground for the weed not to germinate.
Insecticides are sprayed on plants to kill insects, baits are used for rodents or rodenticides chemical and scare crow for birds.
SAFETY MEASURES IN APPLYING CHEMICALS
- Avoid using bare hand when mixing chemicals.
