Role of crop production
A crop is a plant that people grow on purpose. Crop production means growing crops and getting a harvest.
- Food: grains, pulses, vegetables, fruits, oil and sugar.
- Animal feed: fodder, maize and oil cake that feed cows, hens and fish.
- Fibre: cotton and jute become cloth and ropes.
- Fuel and industry: sugarcane gives ethanol, oilseeds give biodiesel, and many crops are raw material for factories.
Crop production also gives work to millions of people and income to villages. Farmland holds soil and helps keep the countryside green.
Daily life and use of crops
Look at your day. Breakfast may be roti, rice or poha (cereals). Dal at lunch is a pulse. Tea needs sugar and milk; the cow ate crop feed. Your shirt may be cotton. The notebook may use sugarcane waste or straw pulp.
Some crops are eaten as they are (fruit). Some are processed: wheat becomes flour, milk becomes curd, oilseeds become oil. Processing makes food last longer and adds value.
Crop distribution and supply-demand trends
Distribution is the journey of a crop from the farm to the buyer: harvest, cleaning and packing, storage, transport, market, shop, home. Good storage (cold rooms, godowns) and roads reduce waste.
Supply is how much of a crop is for sale. Demand is how much buyers want and can pay for. A trend is the way a number moves over the years.
- Supply more than demand: surplus, price falls.
- Demand more than supply: shortage, price rises.
Farmers watch trends. If more people eat vegetables and fruit, farmers may grow more of them. If a crop has a surplus every year, they may switch crops or process it.
Try it
At home, look at your lunch plate. For each item, write which crop it came from and whether it is food, feed, fibre or fuel (a cooked meal is all food, so also look at the room: clothes, paper, soap). Then, in the 3D, set supply high and demand low. Predict the price before you read it.
Key formulas and definitions
- Uses of crops: Food, Feed, Fibre, Fuel
- Supply > Demand: surplus, price falls
- Demand > Supply: shortage, price rises
- Distribution: farm, storage, transport, market, home
- Wastage % = (crop lost / crop harvested) × 100
Worked examples
1. Name the main use of (a) cotton, (b) maize for hens, (c) sugarcane for ethanol.
(a) cotton is fibre, (b) maize for hens is animal feed, (c) sugarcane for ethanol is fuel.
2. A market gets 800 kg of tomatoes but buyers want only 500 kg. What is this situation called and what will probably happen to the price?
Supply (800) is more than demand (500), so there is a surplus of 300 kg. The price will probably fall.
3. A farmer harvests 2,000 kg of potatoes and 150 kg rot in bad storage. Find the wastage percentage.
Wastage = 150 / 2000 × 100 = 7.5%. Better storage would cut this loss.
Common mistakes
- Thinking crops are only for food. They are also feed, fibre and fuel.
- Mixing up supply and demand. Supply comes from sellers; demand comes from buyers.
- Saying a high price always means a good crop. A high price often means a shortage.
- Forgetting distribution. A great harvest helps nobody if it rots before it reaches a market.
