Course Content
Unit 1 –
Agriculture significantly contributes to the national economy. Key principles of crop production focus on efficient soil, water, and nutrient management. The cultivation practices of rice, wheat, chickpea, pigeon-pea, sugarcane, groundnut, tomato, and mango are vital. Understanding major Indian soils, the role of NPK, and identifying their deficiency symptoms are essential for crop health. Fundamental biological concepts like cell structure, mitosis, meiosis, Mendelian genetics, photosynthesis, respiration, and transpiration are crucial for crop science. Biomolecules such as carbohydrates, proteins, nucleic acids, enzymes, and vitamins play significant roles in plant metabolism. Effective management of major pests and diseases in rice, wheat, cotton, chickpea, and sugarcane is critical. Rural development programmes and the organizational setup for agricultural research, education, and extension support agricultural growth. Basic statistical tools, including measures of central tendency, dispersion, regression, correlation, probability, and sampling, aid in agricultural data analysis.

Unit 2
The theory of consumer behavior explains decision-making based on preferences and budget constraints. The theory of demand focuses on the relationship between price and quantity demanded, while elasticity of demand measures demand responsiveness to price changes. Indifference curve analysis shows combinations of goods yielding equal satisfaction, and the theory of the firm examines profit-maximizing production decisions. Cost curves represent production costs, and the theory of supply explores the relationship between price and quantity supplied. Price determination arises from supply and demand interactions, and market classification includes types like perfect competition and monopoly. Macroeconomics studies the economy as a whole, while money and banking analyze monetary systems and financial institutions. National income measures a country's total economic output, and agricultural marketing includes the role, practice, and institutions involved in distribution, along with crop insurance, credit, and cooperatives. Capital formation, agrarian reforms, globalization, and WTO impact Indian agriculture by influencing credit access, investments, and global trade policies.

Unit 3
Farm management involves principles of farm planning, budgeting, and understanding farming systems. Agricultural production economics focuses on factor-product relationships, marginal costs, and revenues. Agricultural finance includes time value of money, credit classifications, and repayment plans. Credit analysis incorporates the 4R’s, 5C’s, and 7P’s, with a history of agricultural financing in India, led by commercial banks and regional rural banks. Higher financing agencies like RBI, NABARD, and World Bank play key roles in credit access, capital formation, and agrarian reforms in India.

Unit 4
Extension education focuses on the principles, scope, and importance of agricultural extension programs. It includes planning, evaluation, and models of organizing extension services, with a historical development in the USA, Japan, and India. Rural development addresses key issues and programs from pre-independence to present times. It involves understanding rural sociology, social change, and leadership, while promoting educational psychology and personality development in agricultural extension. The Indian rural system emphasizes community values, structure, and adult education.

Unit 5
Communication involves principles, concepts, processes, elements, and barriers in teaching methods, with various communication methods and media, including AV aids. Media mix and campaigns, along with cyber extension tools like internet, cybercafés, Kisan Call Centers, and teleconferencing, play a key role. Agriculture journalism focuses on the diffusion and adoption of innovations through adopter categories. Capacity building of extension personnel and farmers is essential, with training for farmers, women, and rural youth. Effective communication and extension methods are crucial for agricultural development.
