5(a) Technologies and Policies for Rainfed Agriculture Sustained crop production in rainfed areas, which constitute 52% of India’s net sown area, relies on integrated technological and policy interventions. Technologically, the focus is on in-situ moisture conservation and drought resilience. Key practices include contour bunding, terracing, and zero-till farming to reduce evaporation and runoff. The introduction of drought-resistant and early-maturing varieties by institutions like ICRISAT, such as hybrid millets and sorghum, has significantly improved yields. Watershed development under the Watershed Development Component of Pradhan Mantri Krishi Sinchayee Yojana (PMKSY) integrates soil and water conservation with on-farm water management.

Policy support is equally critical. The Mahatma Gandhi National Rural Employment Guarantee Act (MGNREGA) provides labor for water harvesting structures, check dams, and farm ponds, ensuring rural livelihoods while enhancing water security. The establishment of the National Rainfed Area Authority (NRAA) aims to coordinate research, extension, and policy formulation specifically for dryland agriculture. Furthermore, crop insurance schemes like PMFBY mitigate the high risk associated with erratic monsoons. Together, these measures create a resilient framework that balances ecological sustainability with economic viability for smallholder farmers in rainfed zones.

5(b) ICTs in Agriculture: Definition and Initiatives Information and Communication Technologies (ICTs) refer to the digital tools and platforms used for the creation, storage, and exchange of information. In agriculture, ICTs bridge the information gap between research, markets, and farmers. The Indian government has launched several initiatives to promote ICT adoption. The Kisan Call Centres (KCCs) provide toll-free (1551) voice-based advisory services in local languages, reaching remote areas. The mKisan SMS portal sends weather alerts, market prices, and crop advisories directly to registered farmers' mobile phones, enabling timely decision-making.

The National Agriculture Market (eNAM) is a pan-India electronic trading portal that creates a unified national market for agricultural produce, reducing middlemen and ensuring price transparency. The Soil Health Card (SHC) portal digitizes soil test data, providing farmers with specific nutrient recommendations for efficient fertilizer use. Recently, the AgriStack initiative aims to create a unified digital identity for farmers, integrating data from various schemes to streamline service delivery. Additionally, drone-based technology is being promoted for crop health monitoring and precision spraying. These initiatives collectively enhance agricultural productivity by ensuring timely, accurate, and accessible information flow, thereby empowering farmers with data-driven insights.

5(c) Minimum Support Price (MSP) and Determination The Minimum Support Price (MSP) is a price floor announced by the Government of India for 23 notified crops to protect farmers from excessive falls in prices. The determination of MSP is a complex process guided by the Committee of Appropriate Cost and Price (CACP). The CACP recommends MSP based on the cost of production, calculated as A2+FL. A2 represents cash expenses (seeds, fertilizers, pesticides, hired labor), while FL is the imputed value of family labor.

The Swaminathan Commission (2006) recommended that MSP should be at least 50% above the cost of production (C2 cost, which includes imputed rent and interest on owned capital). While the government has not formally adopted the 50% margin as a statutory rule, the CACP considers it a benchmark. Other factors influencing MSP include market price trends, demand-supply balance, international price trends, and the fiscal impact on the government. The final MSP is approved by the Cabinet Committee on Economic Affairs (CCEA). This mechanism ensures that farmers receive a guaranteed price, stabilizing income and encouraging the cultivation of essential crops, though its effectiveness is often debated due to limited procurement infrastructure outside major states.

5(d) Pradhan Mantri Fasal Bima Yojana (PMFBY) Pradhan Mantri Fasal Bima Yojana (PMFBY), launched in 2016, is a comprehensive crop insurance scheme aimed at protecting farmers against natural calamities and yield loss. A key feature is the uniform premium rate: 2% for Kharif, 1.5% for Rabi, and 5% for commercial/horticultural crops. The remaining premium is shared between the Central and State governments. For most states, the sharing is 50:50, but for North-Eastern and Himalayan states, the Centre bears 90% of the premium to account for higher risks and lower fiscal capacity.

PMFBY utilizes modern technology for loss assessment, including remote sensing, drones, and smartphone-based Crop Cut Estimates (CCEs), which reduce delays and disputes in claim settlement. The scheme has seen significant progress in coverage, with millions of farmers enrolled annually. However, challenges persist, particularly in eastern states where penetration is lower due to limited banking infrastructure and awareness. Despite these hurdles, PMFBY has improved claim settlement times and provided financial security to a vast number of small and marginal farmers, thereby stabilizing rural incomes.

5(e) Parameters for Irrigation Water Quality The quality of irrigation water is determined by chemical and physical parameters that affect soil structure and plant health. The primary parameters include Electrical Conductivity (EC), which measures salinity; Sodium Adsorption Ratio (SAR), which indicates sodicity hazard; and Residual Sodium Carbonate (RSC), which assesses alkalinity.

EC is measured in μmhos/cm or dS/m. High EC indicates saline water, which can reduce crop yield. SAR is calculated using sodium, calcium, and magnesium concentrations. High SAR leads to soil dispersion and poor permeability. RSC is used to detect residual carbonate hazard, which can cause sodium accumulation in soil. Additionally, specific ion toxicities, such as boron, chloride, and fluoride, are critical parameters. Boron toxicity is particularly damaging to sensitive crops like citrus and vegetables.

Irrigation water is classified into categories based on these parameters. Salinity is classified as C1 (low), C2 (medium), C3 (high), and C4 (very high). Sodicity is classified as S1 (low), S2 (medium), S3 (high), and S4 (very high). The combination of C and S classes (e.g., C3S1) determines the suitability of water for specific crops and soil types. Proper classification ensures that water is matched with appropriate crops and soil management practices, preventing long-term degradation of agricultural land.
