GS Answer Writing – Organic farming | Biotechnology and its applications । Precis
Genetically engineered insulin, also referred to as recombinant DNA insulin or synthetic insulin, is insulin generated via genetic engineering methodologies. Unlike the conventional approach of extracting insulin from animal sources like pigs or cows, genetically engineered insulin is synthesized utilizing modified bacteria or yeast capable of producing human insulin.
The procedure entails the insertion of the human insulin gene into the DNA of bacteria or yeast cells. Subsequently, these genetically modified organisms (GMOs) undergo replication, generating insulin that mirrors the molecular structure of the insulin naturally produced within the human body.
Application in Agriculture:
- Tissue Culture: Cultivating whole plants from small plant parts in a controlled environment. Micropropagation is used to regenerate disease-free plantlets of bananas from tissues of healthy banana plants.
- Somatic Hybridization: Fusing protoplasts of different plant varieties to create hybrid plants. Used for producing new plant hybrids with desired characteristics.
- Genetically Modified Crops: with desirable traits such as pest resistance, disease resistance, drought tolerance, and increased nutritional value.
- Bt Cotton: Engineered with genes like cryIAc and cryIIAb from Bacillus thuringiensis, producing insecticidal proteins that target specific pests.
- Golden Rice: Genetically modified to produce beta-carotene, a precursor of vitamin A, addressing vitamin A deficiency in populations relying heavily on rice as a staple food.
- GM-Mustard:GEAC has approved the environmental release of Dhara Mustard Hybrid-11 (DMH-11).
- ‘Protato’: A genetically modified potato variety enriched with proteins, awaiting final approval for consumption.
- Pest Resistant Plants: RNA interference (RNAi) is used to silence nematode-specific genes in host plants, preventing infestation.
Organic farming is an agricultural system that uses fertilizers of organic origin such as compost manure, green manure. It emphasizes sustainability, biodiversity, and minimal use of synthetic inputs.
| Aspect | Organic Farming | Traditional Farming |
| Soil Fertility | by the addition of organic matter, enhancement of soil biological activity, and mechanical intervention in a cautious manner. | Relies on synthetic fertilizers to replenish soil nutrients |
| Soil Microorganisms | Utilized to provide crop nutrients from insoluble sources | Often overlooked in favor of chemical fertilizers |
| Nitrogen Self-Sufficiency | Achieved through biological nitrogen fixation and recycling of crop residues and manure | Relies on synthetic nitrogen fertilizers |
| Pest and Disease Control | Relies on natural methods such as crop rotation, natural predators, crop diversification, using organic manure, growing resistant varieties | Depends heavily on synthetic pesticides |
| Livestock Management | Prioritizes animal welfare and evolutionary adaptations | May prioritize productivity over animal welfare |
Component of Organic farming :
- Crop Rotation: Rotating crops to maintain soil fertility and reduce pests and diseases.
- Crop Residue: Using leftover plant material as feed for animals and for recycling nutrients.
- Organic Manure: Derived from biological sources to enhance crop growth, protection, and soil productivity.
- Bulky Organic Manure: Includes Farm Yard Manure (FYM), Compost Manure, Green Manure, etc.
- Concentrated Organic Manure: Such as Oilcakes, blood meal, fishmeal, meat meal, etc.
- Waste as Manure: Utilizing industrial waste and properly decomposed municipal and sewage waste.
- Supplementary Nutrient Sources: Powdered rock phosphate, green sand, gypsum, dolomite, etc.
- Bio-fertilizers: Cultures of microorganisms for nitrogen fixation when inoculated into suitable crops.
- Bio-Pesticides: Natural plant products and organisms to control pests.
- Vermicomposting: Organic manure produced by earthworm activity.
- Other Pest Control Methods: Manipulation of crop rotations, pest-resistant varieties, strip cropping, etc.
- Weed Management: Various methods including tillage, irrigation timings, hand weeding, mulching, etc
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”
Paper 4 (Comprehension part) – Precise
Home and College: Sanctuaries of Growth
Home shelters the young who are weak and unexperienced and unable to face the temptations in life. It is a centre of their elementary education and a nursery of sweet affections and pleasant memories. Its magic lasts for ever. A weary mind turn to it for rest. Such is the function of a home and in some measure of the university.
