🌾 The Wonderful World of Science
Class 8 – Chapter 1: Crop Production and Management
Understand how farmers grow crops, manage soil, irrigate fields, and store food for millions. Agriculture is science in action!
🌱 What is Crop Production?
Crops are plants of the same kind cultivated on a large scale. To grow them successfully, farmers follow several steps called agricultural practices — from preparing soil to harvesting and storage.
🌾 Types of Crops
- Kharif Crops: Grown in rainy season (June–Sept), e.g., Paddy, Maize.
- Rabi Crops: Grown in winter (Oct–March), e.g., Wheat, Gram.
🧑🌾 7 Basic Steps in Crop Production
- Preparation of Soil
- Sowing
- Adding Manure and Fertilisers
- Irrigation
- Protection from Weeds
- Harvesting
- Storage
🛠️ Tools Used in Farming
- Plough: Turns and loosens the soil
- Hoe: Removes weeds
- Seed Drill: Sows seeds evenly
- Combine: Harvests and threshes crops
💧 Modern Irrigation Methods
- Sprinkler System: Rotating nozzles mimic rainfall
- Drip System: Saves water by supplying it drop-by-drop to roots
