Types of Farming| Class 12 Geography Notes

Farming in India is as diverse as its landscapes and climates. In India, how farmers grow their crops can differ, often depending on one key factor: water. The availability of water shapes the types of farming practices used. Based on the main source of moisture for crops, farming can be classified as irrigated and rainfed (barani). In this article, you will get detailed notes on Types of Farming from Chapter 3 of your Geography textbook.

Types of Farming

• Farming practices in India vary significantly. It is largely due to differences in climate, soil type, water availability, and technological advancement.
• In particular, the source of moisture for crops plays a major role in determining the type of farming.
• Broadly, farming can be categorized into two types based on the source of moisture:

1. Irrigated farming
2. Rainfed farming

Let’s learn about both of them in detail.

Irrigated Farming

Irrigated farming relies on artificial means to supply water to crops, ensuring that they receive adequate moisture regardless of natural rainfall. This type of farming can be further divided based on the objective of irrigation:

1. Protective Irrigation
2. Productive Irrigation

Protective Irrigation

• Aims to shield crops from the adverse effects of soil moisture deficiency.
• The strategy is to provide just enough soil moisture to cover the maximum possible area. It ensures survival rather than optimal growth.

Productive Irrigation

• Focuses on supplying sufficient soil moisture during the cropping season to achieve high productivity.
• The water input per unit of cultivated land is significantly higher than that of protective irrigation. It aims for the best possible crop yield.

Rainfed Farming

Rainfed farming, , depends on natural rainfall as the primary source of moisture for crops. It is also known as barani. This type of farming can be classified based on the adequacy of soil moisture during the cropping season:

1. Dryland Farming
2. Wetland Farming

Dryland Farming

• It is predominantly found in areas with annual rainfall less than 75 cm.Farmers grow hardy and drought-resistant crops such as ragi (finger millet), bajra (pearl millet), moong (green gram), gram (chickpea), and guar (a fodder crop).Techniques for soil moisture conservation and rainwater harvesting are commonly practiced to make the most of the limited water.

Wetland Farming

• Occurs in regions where rainfall exceeds the soil moisture requirements of plants during the rainy season.
• These areas may experience challenges such as flooding and soil erosion.
• Water-intensive crops like rice, jute, and sugarcane are cultivated, and aquaculture is practiced in freshwater bodies.

Importance of Adaptation

The choice between these farming types and their subcategories depends on several factors, including the local climate, soil conditions, and available water resources. Each type of farming has adapted to its environment in unique ways:

• Advanced irrigation technologies such as drip and sprinkler systems are increasingly used in productive irrigation to maximize water efficiency and crop yield.
• Dryland farmers often employ innovative strategies like contour plowing and the use of mulch to reduce water loss and improve soil fertility.
• In flood-prone areas, farmers may construct raised beds for crops or utilize integrated farming systems that combine agriculture with fish farming to enhance productivity and sustainability.

Conclusion

Understanding the types of farming based on the source of moisture is important for developing effective agricultural practices and policies. By tailoring farming techniques to suit specific environmental conditions, farmers can optimize water use, protect the environment, and achieve sustainable crop production.

Types of Farming- FAQs

What is irrigated farming?

Irrigated farming is a method where water is artificially supplied to crops to ensure they receive adequate moisture, regardless of natural rainfall.

How is protective irrigation different from productive irrigation?

Protective irrigation aims to prevent crop failure by minimizing soil moisture deficiency, while productive irrigation seeks to maximize crop yield by ensuring optimal soil moisture levels throughout the cropping season.

What crops are typically grown in dryland farming?

Dryland farming focuses on drought-resistant crops such as ragi (finger millet), bajra (pearl millet), moong (green gram), gram (chickpea), and guar (fodder crop).

What is the main challenge of wetland farming?

The main challenges include managing excess water, which can lead to flooding and soil erosion, while optimizing the growth of water-intensive crops like rice, jute, and sugarcane.

Why is rainwater harvesting important in dryland farming?

In regions with low annual rainfall, rainwater harvesting helps conserve soil moisture and provides a supplemental water source, making it crucial for sustaining crops in dryland farming.

Can aquaculture be integrated with wetland farming?

Yes, aquaculture, or fish farming, can be integrated with wetland farming in areas with excess rainfall, utilizing freshwater bodies for both crop cultivation and aquaculture to enhance productivity and sustainability.

What are some advanced irrigation technologies used in productive irrigation?

Drip and sprinkler irrigation systems are advanced technologies used in productive irrigation to deliver water directly to the plant roots or spray over the crops, respectively, improving water efficiency and crop yields
