Study Notes
Crop Production and Management
- Food has to be produced on a large scale to provide for a large population, and regular production, proper management, and distribution are necessary.
- Agriculture was born around 10,000 B.C.E. when people started cultivating land and producing rice, wheat, and other food crops.
Types of Crops
- Crops can be classified as kharif crops (sown in the rainy season) and rabi crops (grown in the winter season).
- Examples of kharif crops include paddy, maize, soyabean, groundnut, and cotton.
- Examples of rabi crops include wheat, gram, pea, mustard, and linseed.
Basic Practices of Crop Production
- Preparation of soil is the first step in crop production.
- Soil needs to be tilled or ploughed to loosen it and allow roots to breathe easily.
- The process of loosening and turning of the soil is called tilling or ploughing.
- Ploughs are made of wood or iron and are used to break soil clumps and add fertilizers to the soil.
Agricultural Implements
- The main tools used for crop production are the plough, hoe, and cultivator.
- A hoe is a simple tool used for removing weeds and loosening the soil.
- A cultivator is a tractor-driven tool used for ploughing the soil.
- Traditional tools used for sowing seeds include a funnel-shaped tool and a seed drill.
Sowing
- Sowing is an important part of crop production.
- Good quality, healthy seeds of a good variety are selected for sowing.
- Seeds are sown at a uniform distance and depth to promote healthy growth.
Adding Manure and Fertilisers
- Substances added to the soil to promote healthy growth of plants are called manure and fertilizers.
- Manure is an organic substance obtained from the decomposition of plant or animal waste.
- Fertilizers are chemicals rich in a particular nutrient, produced in factories.
- Examples of fertilizers include urea, ammonium sulphate, super phosphate, potash, and NPK (Nitrogen, Phosphorus, Potassium).
- Excessive use of fertilizers can lead to soil pollution and water pollution.
Advantages of Manure
- Manure enhances the water-holding capacity of the soil.
- Manure makes the soil porous, allowing for easy exchange of gases.
- Manure increases the number of friendly microbes in the soil.
- Manure improves the texture of the soil.
Irrigation
-
Irrigation is the supply of water to crops at regular intervals.
-
The time and frequency of irrigation vary depending on the crop, soil, and season.
-
In summer, the frequency of watering is higher due to increased evaporation of water from the soil and leaves.### Importance of Water
-
Water is essential for proper growth and development of plants.
-
Plant roots absorb water along with minerals and fertilizers.
-
Water helps in germination of seeds and transports nutrients to different parts of the plant.
Sources of Irrigation
- Wells, tubewells, ponds, lakes, rivers, dams, and canals are sources of water for irrigation.
- Traditional methods of irrigation include moat (pulley system), chain pump, dhekli, and rahat (lever system).
Modern Methods of Irrigation
- Modern methods of irrigation help to use water economically.
- Sprinkler system is useful for uneven land and saves water.
- Drip system is best for watering fruit plants, gardens, and trees, and is a boon in regions with poor water availability.
Crop Protection from Weeds
- Weeds are undesirable plants that grow naturally with crops and compete for water, nutrients, space, and light.
- Weeds can interfere with harvesting and can be poisonous to animals and humans.
- Farmers adopt various methods to remove weeds, including tilling, physical removal, and using weedicides.
Harvesting and Storage
- Harvesting is an important task that involves cutting mature crops.
- Weeds are removed, and grains are separated from chaff through threshing.
- Grains are stored in jute bags or metallic bins to protect them from pests and microorganisms.
- Large-scale storage is done in silos and granaries.
Food from Animals
- Animals provide various kinds of food, such as milk, fish, and cod liver oil.
- Animal husbandry involves providing proper food, shelter, and care to animals.
Agricultural Practices
-
Agricultural practices include preparation of soil, sowing seeds, irrigation, weeding, harvesting, and storage.
-
These practices help to provide food to the growing population.### Farm Visit
-
Himanshu, Mohan, David, and Sabiha visited Shri Jiwan Patel's farmhouse to collect seeds and learn about crops.
-
Shri Patel's grandfather started farming about 75 years ago, and they mainly grow wheat, gram, soyabean, and moong.
Traditional vs Modern Agriculture
- Traditional methods used tools like sickle, bullock plough, trowel, and relied on rainwater for irrigation.
- Modern methods use tractors, cultivators, seed drills, and harvesters, with good quality seeds, soil testing, manure, and fertilizers.
- Modern technology provides better crop yields, with 9-11 quintals of gram and 20-25 quintals of wheat per acre.
Importance of Earthworms
- Earthworms help farmers by turning and loosening soil for proper aeration.
Seeds and Fertilizers
- The students collected seeds, fertilizers, and soil samples from Shri Patel's farm.
Key Takeaways
- Awareness of new technology is important for better crop yields.
- Shri Patel provided useful information and made the visit pleasant for the students.
