Study Notes

Advantages of Manure

Enhances water holding capacity of soil, improving moisture retention.
Increases soil porosity, facilitating easier gas exchange.
Boosts population of beneficial microbes, promoting soil health.
Improves soil texture, aiding in overall plant growth.

Irrigation

Defined as the supply of water to crops for agricultural purposes.
Two main types of irrigation sources:
- Traditional Methods:
  - Moat System
  - Chain Pump System
  - Dhekli System
  - Rahat System
- Modern Methods:
  - Sprinkler System
  - Drip System

Weeds

Undesirable plants that compete with crops for nutrients and space.

Weedicides

Sprays or chemicals used to kill weeds and protect crops from unwanted plant growth.

Harvesting

The process of cutting crops when they are ready for collection.

Threshing

Separating seeds from the remaining waste or plant material after harvesting.

Storage

A designated place for keeping harvested crops to prevent spoilage.

Winnowing

A method or machine used to separate seeds from chaff and other waste materials.

Animal Husbandry

The practice of breeding and caring for animals, providing proper food and care to yield products like milk and eggs.

Crop Production and Management

Importance of food is rooted in energy provision for daily activities.
Definition: A crop consists of plants of the same kind cultivated over a large area.

Types of Crops

Kharif Crops:
- Sown during the rainy season (June to September).
- Examples: Paddy, maize, soybean, groundnut, cotton.
Rabi Crops:
- Grown in the winter season (October to March).
- Examples: Wheat, gram, pea, mustard, linseed.

Tilling and Ploughing

Defined as the process of loosening and turning the soil to prepare for planting.

Soil Crumbs

Large pieces of soil that contribute to soil structure and aeration.

Seed Floatation

Damaged seeds tend to float on water because their density decreases.

Sowing

The act of preparing soil and placing seeds in it for crop growth.

Manure and Fertilizers

Substances added to soil to provide essential nutrients for the healthy growth of crops.

Difference Between Fertilizer and Manure

Manure is organic, derived from animal waste, while fertilizers can be either organic or synthetic, providing concentrated nutrients.
