RAEO exam mainly covers agriculture and related subjects. Candidates should have basic knowledge of crop production, soil science, irrigation, horticulture, and agricultural extension.
In the 2017 RAEO exam, the paper was conducted for 200 marks.
However, in the 2023 exam pattern, the paper was reduced to 100 objective questions carrying 100 marks.
To make your preparation easier, we have shared the complete subject-wise RAEO syllabus below.
Latest CG RAEO Syllabus
Agriculture Subjects and Topics List
Agriculture
Agriculture is the foundation of the RAEO syllabus. This section explains how agriculture has developed over time and how crop production has improved in India and Chhattisgarh.
Candidates should understand the history of agricultural development and major agricultural revolutions such as the Green Revolution that increased food production.
This section also includes topics related to crop area, production, and productivity. Students should know how fertilizer use and irrigation systems influence crop yield.
Knowledge about national and international agricultural research organizations is also important because these institutions play a key role in agricultural innovation and development.
Agronomy
Agronomy focuses on the scientific management of field crops. It helps farmers improve crop production through better cultivation practices. Candidates should understand the definition, scope, and importance of agronomy and how it connects with other agricultural sciences.
This section includes agro-climatic zones of India and Chhattisgarh, classification of crops, and factors affecting crop production such as soil, climate, and nutrients.
Topics like tillage, cropping systems, crop rotation, and crop diversification are also important. Students should also learn about sustainable agriculture, rainfed farming, dry farming, and water conservation practices.
Agronomic practices such as weed management, pest and disease control, fertilizer management, and yield improvement methods are also covered in this section.
Water Management
Water management is essential for successful crop production. This topic explains how water resources are used efficiently in agriculture.
Candidates should understand irrigation concepts, irrigation development in India and Chhattisgarh, and the relationship between soil, plant, and water. Important topics include crop water requirement, evapotranspiration, effective rainfall, and irrigation scheduling.
Different irrigation methods such as surface irrigation, sprinkler irrigation, and drip irrigation are also important.
Students should also learn about irrigation efficiency, water use efficiency, watershed management, and drainage systems used to remove excess water from agricultural land.
Agricultural Meteorology and Crop Physiology
Agricultural meteorology studies the effect of weather and climate on agriculture. It helps farmers understand how temperature, rainfall, wind, and humidity influence crop growth.
Candidates should study atmospheric composition, weather and climate concepts, global warming, cyclones, and weather hazards. Understanding these factors helps in planning agricultural activities.
Crop physiology explains the internal processes that occur inside plants. Topics include seed germination, seed viability, photosynthesis, respiration, transpiration, and plant growth regulators.
Knowledge of C3 and C4 plants is also important in understanding crop productivity.
Entomology and Plant Pathology
This section deals with insects and diseases that affect crops. Crop losses due to pests and diseases can be very high, so understanding their management is very important.
Students should learn the morphology, classification, and ecology of insects. Syllabus also includes major insect pests of cereals, pulses, and oilseed crops grown in Chhattisgarh.
Integrated Pest Management (IPM) is an important concept that combines biological, cultural, and chemical methods to control pests in an environmentally safe way.
This Section also covers stored grain pests, plant pathogens, and basic nematology.
Soil Science
Soil science focuses on soil formation, soil properties, and soil fertility. It explains how soil supports plant growth and how nutrient management improves crop productivity.
Candidates should understand soil formation processes, soil components, soil profile, and physical properties of soil. The syllabus also includes the soils of Chhattisgarh and land capability classification.
Important topics include soil organic matter, humus, carbon-nitrogen ratio, and soil water relationships.
Students should also learn about essential plant nutrients, nutrient deficiencies, fertilizer use efficiency, and types of manures and fertilizers used in agriculture.
Genetics and Plant Breeding
Genetics and plant breeding focus on improving crop varieties to increase productivity and resistance to pests and diseases.
Students should understand Mendel’s laws of inheritance and different types of gene interactions. Topics like mutation, DNA and RNA structure, and plant reproduction systems are also included.
Plant breeding methods such as hybridization, heterosis, and mutation breeding are important for developing improved crop varieties.
Syllabus also includes seed production, seed quality, and different classes of seeds used in agriculture.
Extension Education and Agricultural Extension
Extension education is the process of transferring agricultural knowledge from research institutions to farmers. It helps farmers adopt new technologies and improve farming practices.
Candidates should understand the meaning, scope, and importance of extension education. Topics also include social structure, social values, communication methods, and community development.
Agricultural development programs and extension communication methods are also covered in this section because RAEO officers work directly with farmers and rural communities.
Agricultural Economics
Agricultural economics explains how economic principles apply to farming and agricultural production.
Students should understand basic concepts of economics such as demand, supply, and production economics. Farm management practices are also included in this section.
Knowledge of livestock and fisheries is also important because these activities contribute to rural income and agricultural sustainability.
Horticulture
Horticulture deals with the cultivation of fruits, vegetables, flowers, plantation crops, and medicinal plants. It plays an important role in improving farm income and crop diversification.
Candidates should understand the package of practices for horticultural crops including soil management, irrigation, fertilizer application, pest management, and yield improvement.
Other important topics include plant propagation methods, nursery management, protected cultivation, post-harvest technology, orchard management, and irrigation management for horticultural crops.
Biotechnology
Biotechnology focuses on the genetic and biochemical processes of plants. It helps scientists develop improved crop varieties with better yield and resistance.
Topics include genetic material, DNA replication, chromosomes, mutation, and heredity. Students should also understand plant cell structure and biochemical processes.
Syllabus also includes metabolism of carbohydrates, proteins, and lipids, as well as enzymes and vitamins. Biotechnology applications in food and pharmaceutical industries are also included.
Agricultural Engineering
Agricultural engineering deals with the use of machinery, tools, and technology in farming operations.
Candidates should study surveying and land leveling methods used in agriculture. Irrigation equipment, water lifting devices, and irrigation measurement techniques are also important.
This section also includes soil erosion and conservation methods, farm machinery used for tillage and harvesting, and post-harvest management of agricultural and horticultural produce.
