Earthworms and microbes, by turning and loosening the soil, enhance aeration and add humus, improving soil structure and nutrient availability for plants. NCERT Class 8 Science Chapter 1 Crop Production and Management

Loosened soil allows roots to penetrate easily and breathe, facilitating better growth. It also promotes the activity of earthworms and microbes, enhancing soil quality. NCERT Class 8 Science Chapter 1 Crop Production and Management

Adding manure and fertilizers enrich the soil with essential nutrients, promoting plant growth and ensuring better crop yield. NCERT Class 8 Science Chapter 1 Crop Production and management

Soil preparation for crop cultivation involves plowing, leveling, and adding organic matter to create a suitable environment for plant growth. NCERT Class 8 Science Chapter 1 Crop Production and management

Agricultural practices are tasks undertaken by farmers for crop cultivation, including soil preparation, sowing, adding manure, irrigation, weed protection, harvesting, and storage. NCERT Class 8 Science Chapter 1 Crop Production and Management

Besides Kharif and Rabi crops, pulses and vegetables are grown during the summer season at various places in India. NCERT Class 8 Science Chapter 1 Crop Production and Management

Rabi crops are grown in the winter season, from October to March. Examples of Rabi crops include wheat, gram, pea, mustard, and linseed. NCERT Class 8 Science Chapter 1 Crop Production and Management

The rainy season in India is generally from June to September. Kharif crops like paddy, maize, soybean, groundnut, and cotton are sown during this period. NCERT Class 8 Science Chapter 1 Crop Production and Management

Crops are classified into Kharif (rainy season) and Rabi (winter season) types. Kharif crops include paddy, maize, soybean, groundnut, and cotton. Rabi crops include wheat, gram, pea, mustard, and linseed. NCERT Class 8 Science Chapter 1 Crop Production and Management

The primary purpose of photosynthesis in plants is to convert light energy into chemical energy (glucose), providing the plant with a source of nutrition and releasing oxygen as a byproduct. NCERT Class 8 Science Chapter 1 Crop Production and management
