Organic & Zero Budget Natural Farming: Core Principles, Techniques, Characteristics, Benefits, Challenges & Scope in Rajasthan is an important concept in Biology that emphasizes sustainable agriculture without the use of chemical fertilizers or pesticides. This farming method relies on natural resources, traditional practices, and soil-friendly techniques to improve crop productivity while maintaining ecological balance, making it highly relevant for Rajasthan’s unique climatic and soil conditions.
Organic Farming
- Organic farming is an ecological and holistic agricultural system that aims to produce food in a way that enhances and sustains the health of soil, ecosystems, and people.
- It involves the use of natural inputs and methods to maintain soil fertility, control pests, and ensure sustainable farming practices without relying on synthetic chemicals, pesticides, or fertilizers.
Core Principles of Organic Farming
The Principle of Health
- Focuses on enhancing and sustaining the health of soil, plants, animals, and humans.
- Avoids toxic chemicals and synthetic fertilizers, creating a balanced and thriving ecosystem.
The Principle of Ecology
- Aligns farming practices with natural ecosystems.
- Promotes biodiversity by integrating crops, livestock, and beneficial organisms like pollinators and natural predators.
The Principle of Fairness
- Encourages fair relationships among farmers, workers, consumers, and the environment.
- Promotes fair labor practices, better livelihoods for farmers, and safe, healthy food for consumers.
The Principle of Care
- Emphasizes responsibility and sustainability for the long term.
- Aims to preserve natural resources, biodiversity, and ecosystems for future generations.
Techniques and Practices in Organic Farming
Crop Rotation
- Involves alternating crops to improve soil fertility, control pests, and manage weeds naturally. Ex.- Legumes (e.g., beans or peas) followed by cereals (e.g., wheat or rice) to replenish nitrogen in the soil.
Intercropping
- Planting two or more different crops together in the same field. For example, planting legumes with cereals helps to fix nitrogen in the soil, enriching it for subsequent crops.
Crop Residues
- Used as animal feed and for nutrient recycling in the soil. Example: Rice husk and wheat straw are often composted and added back to the soil.
Mulching:
- Mulching is the process of covering the soil with organic materials like straw, grass, or leaves.
- This helps retain soil moisture, suppress weeds, and prevent soil erosion while gradually improving soil organic content as the mulch decomposes.
Organic Manure
- Derived from biological sources, it enhances crop growth, protection, and soil productivity.
- Types of Organic Manure:
- Bulky Manures: Farmyard manure (FYM), compost, green manure.
- Concentrated Manures:Neem Oilcakes, blood meal, fishmeal, meat meal, horn meal, hoof meal.
Waste as Manure
- Industrial by-products like distillery spent wash, molasses, and press mud (after decomposition).
- Supplementary sources: Rock phosphate, green sand, gypsum, dolomit
Bio-fertilizers
- Microorganisms that fix atmospheric nitrogen, promoting natural nutrient enrichment. Example: Rhizobium for legumes, Azotobacter for cereals, and Azolla for paddy fields.
Bio-pesticides
- Derived from natural plant products (alkaloids, terpenoids, phenolics) and other sources. Examples:
- Botanicals: Neem oil spray for controlling aphids and whiteflies.
- Biological Agents: Bacillus thuringiensis (Bt) for caterpillars, Trichogramma for managing moth eggs.
- Pheromones: Traps to disrupt insect mating, such as in fruit flies.
Vermicomposting
- Nutrient-rich organic manure produced by earthworms digesting biomass, offering superior nutrients compared to FYM.
Pest Management Methods
- Includes crop rotation, pest-resistant varieties, strip cropping, trap cropping, destruction of alternate host plants, adjusting planting dates and seeding rates, and mechanical pest removal.
Weed Management
- Combines methods like:
- Tillage, irrigation scheduling, and seed selection.
- Use of weed-free seeds, cattle foraging, flooding, mulching, composting, hand weeding, and proper disposal of straw.
Agroforestry:
- Agroforestry is the practice of integrating trees into agricultural systems. Trees provide shade, improve soil structure, reduce wind erosion, and can serve as habitat for beneficial species, all of which contribute to a more balanced ecosystem.
Water Management:
- Organic farms often use rainwater harvesting systems and efficient irrigation techniques such as drip irrigation to manage water usage.
- These systems minimize waste and ensure crops receive the right amount of water without excess runoff or evaporation.
Characteristics of Organic Farming
- Long-term Soil Fertility
- Maintained through the addition of organic matter, enhanced biological activity, and careful mechanical intervention to protect soil structure.
- Role of Soil Microorganisms
- Microorganisms play a vital role in releasing nutrients from insoluble sources, supporting plant growth naturally.
- Self-sufficiency in Nitrogen
- Achieved via biological nitrogen fixation using leguminous plants and recycling of crop residues and livestock manure.
- Weed, Disease, and Pest Management
- Managed through sustainable practices like crop rotation, introducing natural predators, crop diversification, organic manure, growing resistant varieties, and minimal thermal, biological, or chemical interventions.
- Livestock Management
- Focused on extensive management practices that respect animals’ natural adaptations, behavioral needs, and welfare.
- Wildlife and Habitat Conservation
- Prioritizes reducing the environmental impact of farming to conserve wildlife and natural habitats.
Scope in rajasthan
- The Rajasthan government has set an ambitious target of converting about 1.20 lakh hectares of agricultural land into organic farming areas.
- Rajasthan Organic Farming Mission, with an outlay of Rs 600 crore, aims to benefit around 4 lakh farmers. It aims to provide organic seeds, bio- fertilisers and pesticides to farmers
- To boost organic farming in the state, the Rajasthan government has decided to go to the grassroots to encourage it, by setting up district-level certification units and testing labs.
- Rajasthan Organic Farming Policy 2017:
- Arid & semi-arid regions of State have low consumption of pesticides and fertilizers, which makes it easy to go for organic conversion without significant yield loss during conversion period
- the districts having potential for organic production are Jaisalmer, Barmer, Jodhpur, Jalore, Pali, Sirohi, Dungarpur, Nagaur and Jhunjhunu.
- Vision → Establishment of brand “Organic Rajasthan”

Zero Budget Natural Farming (ZBNF)
- ZBNF is a farming method that reduces costs by using natural resources instead of synthetic fertilizers and chemicals. It focuses on sustainability, soil health, and high yields
- It was developed by Subhash Palekar in India.
Definition:
ZBNF is a farming method that reduces costs by using natural resources instead of synthetic fertilizers and chemicals. It focuses on sustainability, soil health, and high yields, and was developed by Subhash Palekar in India.
Core Principles of ZBNF
- Zero Cost Inputs
- Uses locally available natural materials (cow dung, cow urine, indigenous microorganisms) to replace expensive chemicals.
- Natural Farming Practices
- Works with nature to maintain healthy soil, plants, and water systems, promoting biodiversity.
- Minimal External Inputs
- Reduces reliance on costly fertilizers, pesticides, and seeds by using local resources.
Key Components of Zero Budget Natural Farming
Panchamrit
