Welcome to class!
In today’s class, we will be talking about the roles of science and technology in agricultural development. Enjoy the class!
Roles of Science and Technology in Agricultural Development
Science and Technology have played significant roles in the development of agriculture in Nigeria and many other countries of the world. These roles include
- Modern farm machinery: – The development of modern farm implement such as tractor, plough, planter, harvester, sheller to replace old simple tools such As hoe and cutlass has been made possible by science and technology. This has greatly increased productivity (commercial farming) and farm work becomes easier, faster and attractive.
- Agro-climatology: – Science has been able to explain the ideal climatic conditions for plants and animals. Farmers are equally helped to understand the weather and climate of their area and can determine the type of crops to grow and animals to rear.
- Pests and disease control: – Chemicals in the form of pesticides, fungicides, nematicides, fumigants have been developed by science and technology to combat the problems caused by pests and disease.
- Crops and animals improvement: – Through genetics and breeding, improved crop varieties and animal breeds which possess desirable qualities such as disease resistance, fast growth, early maturity, high yield have been developed.
- Soil fertility: – The development and application of organic manure and inorganic fertilizers by science and technology has been able to solve the problem of soil infertility and also increase crop yield. Farmers can also test the soil; determine the nutrient deficiencies and the type of crop to plant on farmland.
- Animal health management: – Feeds are formulated to meet the nutritional needs of farm animals, other factors such as ventilation, sanitation, immunization and medication have been put in place by science and technology to ensure good health and productivity of farm animals.
- Storage and processing facilities: – To preserve excess farm produce and to avoid wastage, modern storage facilities such as silos, cold rooms and processing facilities such as millers, shellers have been developed by science and technology.
- Transportation network: – Science and technology have been able to develop roads, railways and waterways linking food-producing areas to urban centres.
- Soil and water conservation: – Through irrigation, drainage and erosion control, the soil is preserved from losing its fertility and water is made available at optimum level required for plant growth.
- Land surveying: – Surveying equipment is made available by science and technology and with this equipment, the physical feature and size of farmland can be determined. This help to determine the suitability of a farm location for various uses and input requirement of given farmland.
- Agricultural system: – Improved farm management system such as crop rotation, mixed farming, rotational grazing has been put in place by science and technology to maintain soil fertility, increase yield and maximize land use.
