Crop Production and Management
Class 8 · Science
4 ideas in Class 8 Science, explained in plain words, with games and quizzes to practise.
Crops and Growing Seasons
Part of: Crop Seasons
A crop is a large-scale planting of one kind of plant. Kharif crops are sown in the rainy season, while rabi crops grow in winter.
Why it matters. Season and local climate affect which crop can grow well.
Try it in two minutes
- Name the season for sowing.
- Sort the crop as kharif or rabi.
- Consider its water needs.
Try at home. Sort familiar grains into crops grown in rainy or winter seasons.
Preparing Soil and Sowing Seeds
Part of: Soil and Sowing
Tilling turns and loosens soil so roots can grow and air can reach them. Farmers select healthy seeds and sow them with enough spacing and depth.
Why it matters. Good preparation supports roots and reduces overcrowding.
Try it in two minutes
- Loosen soil before sowing.
- Choose clean healthy seeds.
- Place seeds at suitable spacing and cover them.
Try at home. Compare two seed-starting plans and predict which avoids crowding.
Soil Nutrients and Watering
Part of: Inputs and Irrigation
Manure comes from decomposed plant or animal waste and adds humus. Fertilisers are factory-made nutrient-rich substances. Irrigation supplies water to crops at intervals.
Why it matters. The right inputs help crops grow while protecting soil and water.
Try it in two minutes
- Compare where each nutrient source comes from.
- Choose a watering method for the field.
- Consider effects of excess fertiliser.
Try at home. Find examples of organic waste that could become manure.
Weeding, Harvesting and Storage
Part of: Crop Care and Storage
Weeds compete with crops for water, nutrients, light and space. Mature crops are cut at harvest; grains are separated from chaff and dried before storage.
Why it matters. Each step protects crop growth and prevents stored grains from spoiling.
Try it in two minutes
- Remove weeds before they make seeds.
- Cut the crop when mature.
- Dry grains and store them away from pests and moisture.
Try at home. Make a simple sequence from weeding to storage.
