Agricultural Practices
Unlock Audio Book
Signup and Enroll to the course for listening the Audio Book
In order to provide food to our growing population, we need to adopt certain agricultural practices.
Detailed Explanation
Agricultural practices are essential methods adopted by farmers to ensure sufficient food production. These practices include soil preparation, planting, and crop maintenance, which help increase yield and manage resources effectively.
Examples & Analogies
Think of agricultural practices like a recipe for baking a cake. Just as you need to follow steps carefully to bake a delicious cake, farmers must follow specific practices to grow healthy crops.
Crops Definition
Unlock Audio Book

Same kind of plants cultivated at a place constitute a crop.
Detailed Explanation
A crop refers to a group of plants that are all of the same species and are grown together in a specific area. For instance, if a farmer grows wheat in a large field, all the wheat plants there together make up one crop.
Examples & Analogies
Imagine a garden where you have planted only sunflowers. All of those sunflowers together represent a crop. It’s like creating a team of players, where each player is the same type – together they make a stronger unit.
Types of Crops

In India, crops can be broadly categorised into two types based on seasons - rabi and kharif crops.
Detailed Explanation
Crops are classified into two main categories based on the seasons they are planted in. Rabi crops are sown in the winter and harvested in the spring, while kharif crops are sown with the onset of monsoon rain and harvested in the autumn. Understanding this helps farmers plan their planting schedules effectively.
Examples & Analogies
Think of it as two different sports seasons: basketball season (rabi) happens during the winter and spring, while cricket season (kharif) takes place during the rainy months. Each sport requires specific conditions to thrive.
Soil Preparation
Unlock Audio Book

It is necessary to prepare soil by tilling and levelling. Ploughs and levellers are used for this purpose.
Detailed Explanation
Soil preparation is a crucial first step in crop production. It involves tilling (mixing and aerating the soil) and leveling (making the soil even) to create a suitable environment for seeds to grow. Tools like ploughs and levellers help make this process efficient.
Examples & Analogies
Preparing soil is like preparing a bed for a new mattress: you must make sure it is level and ready to support the mattress properly. Without proper preparation, the mattress (or seeds) won't settle in well.
Seed Selection and Sowing
Unlock Audio Book

Sowing of seeds at appropriate depths and distances gives good yield. Good variety of seeds are sown after selection of healthy seeds. Sowing is done by seed drills.
Detailed Explanation
Selecting the right seeds and ensuring they are sown at the correct depth and distance apart is vital for a successful crop yield. This helps each plant get enough space, sunlight, and nutrients. Modern technology has introduced seed drills for efficient sowing.
Examples & Analogies
Imagine planting flowers in your garden; if you plant them too close together, they won't grow well. Just like flowers need space and care, so do crops need proper seeds and planting techniques for a bountiful harvest.
Soil Enrichment
Unlock Audio Book
Signup and Enroll to the course for listening the Audio Book
Soil needs replenishment and enrichment through the use of organic manure and fertilisers. Use of chemical fertilisers has increased tremendously with the introduction of new crop varieties.
Detailed Explanation
To support plant growth, soil must be enriched with nutrients, which can be done through organic manure (natural) and chemical fertilizers (manufactured). As more efficient crop varieties have been developed, the use of fertilizers has risen to maximize yields.
Examples & Analogies
Think of enriching soil like adding vitamins to your diet. Just as vitamins help you grow strong and healthy, nutrients in soil help plants thrive and produce better.
Irrigation Importance
Unlock Audio Book
Signup and Enroll to the course for listening the Audio Book
Supply of water to crops at appropriate intervals is called irrigation.
Detailed Explanation
Irrigation is the method used to provide crops with water at intervals deemed necessary for their growth. Different crops require different watering schedules based on their needs, and irrigation practices can greatly affect the health of the crops.
Examples & Analogies
Think of irrigation as giving a plant a drink of water. Just as you need to make sure your plants aren't thirsty, farmers must ensure their crops get the right amount of water to grow well.
Weeding
Unlock Audio Book
Signup and Enroll to the course for listening the Audio Book
Weeding involves removal of unwanted and uncultivated plants called weeds.
Detailed Explanation
Weeds are unwanted plants that can take away nutrients and space from crops, harming their growth. Weeding is the process of removing these plants manually or through chemicals to protect crops.
Examples & Analogies
Imagine trying to study in a room full of distractions. Weeds are like those distractions; they compete with crops for resources, so removing them is important for the crops to thrive.
Harvesting
Unlock Audio Book

Harvesting is the cutting of the mature crop manually or by machines.
Detailed Explanation
Harvesting is the final step in crop production, involving the collection of mature crops. This can be done by hand with tools like a sickle or mechanically with harvesters. Proper harvesting ensures that the crops are collected efficiently.
Examples & Analogies
Think of harvesting like picking ripe fruit from a tree. You want to make sure you collect the fruit at the right time so it’s ready to be eaten. Similarly, crops need to be harvested at the right point for optimal quality.
Threshing
Unlock Audio Book
Signup and Enroll to the course for listening the Audio Book
Separation of the grains from the chaff is called threshing.
Detailed Explanation
Threshing is the process of separating the edible parts of the grain from the non-edible parts (chaff) after harvesting. This can be done using various machines or manually.
Examples & Analogies
Imagine peeling a banana. Once you remove the peel, you’re left with the part you can eat. Threshing is like that for grains; it gets rid of the parts we don't eat.
Storage of Grains

Proper storage of grains is necessary to protect them from pests and microorganisms.
Detailed Explanation
After harvesting and threshing, grains must be stored correctly to avoid spoilage and contamination from pests and microorganisms. This can involve drying them out and keeping them in safe environments.
Examples & Analogies
Storing grains is like keeping food in the fridge to keep it fresh. Just as you want to protect your food from spoiling, farmers must ensure their grains are stored safely for later use.
Animal Husbandry
Unlock Audio Book

Food is also obtained from animals for which animals are reared. This is called animal husbandry.
Detailed Explanation
Animal husbandry involves the breeding and care of animals to provide food products such as milk, eggs, and meat. This practice is important for supplementing the food supply alongside crop production.
Examples & Analogies
Animal husbandry is like having a pet that you feed and take care of; in return, it might provide you with milk or eggs. Just as we look after pets, farmers take care of animals for essential food resources.
