Materials of construction. Heat treatments. Principle of selection of farm machines. Field capacities. Farm economics. Questions & Answers.

3. Farm mechanization :- Introduction:- India is a vast country covering about 3.29mh Geographical area. About 166mh is cultivable land, and net area sown is about 142mh. The farm holdings in India are classified as:- Marginal farmers (<1 ha) S mall farmers (1-2 ha) Semi-medium farmers (2-4 ha) Medium farmers (4-10 ha) Large farmers (>10 ha)

4. India is producing yearly more than 2.5 lakh tractors, 10,000 power tillers, 4.5 lakh sprayers & dusters, 9.5 lakh pumping sets and 2000 combine Harvesters. At present Agriculture machinery population in India is estimated at about 150 million which includes about 3 million tractor and other self propelled machines.

5. Scope of farm mechanization:- To improve irrigation facilities. Introduction of H.Y.V. seeds. Introduction of dose of fertilizers and pesticides for different types of crops. Introduction of new crops. Multi cropping system & intensive farming.

6. Classification of farm machines :-

7. Materials of construction :- Ferrous materials . Cast iron Steel 2. Non-ferrous materials. Copper Aluminium Brass Bronze Wood Rubber Plastic etc.

8. Heat treatments:- There are several methods of heat treatment such as:- Hardening Annealing Tempering Case hardening Carburising Nitriding Carbonitriding Cyaniding Induction hardening Flame hardening

9. Principle of selection of farm machines :- Land holding Soil condition Climatic condition Cropping pattern Repairing facilities Running cost Initial cost and resale value Test report
