Quantitative Aptitude and Reasoning
Percentage: x% of y = (x/100)×y; increase by p% then decrease by p% gives net decrease of (p²/100)%; successive changes multiply factors.
Ratio and proportion: if a:b = c:d then ad = bc; compound ratio; divide a quantity in ratio m:n as parts m/(m+n) and n/(m+n).
Average: sum = average × number; if each item increased by k, average increases by k; weighted average formula.
Time, speed, distance: distance = speed × time; average speed for equal distances = 2xy/(x+y); relative speed for opposite directions = sum of speeds.
Profit and loss: profit% = (SP-CP)/CP ×100; discount% = (MP-SP)/MP ×100; successive discounts multiply factors.
Simple and compound interest: SI = P×R×T/100; CI = P[(1+R/100)^T – 1]; difference for 2 years = P(R/100)².
Reasoning: number series (differences, ratios, squares/cubes), coding-decoding, blood relations, direction sense, syllogisms.
Data interpretation: tables, bar charts, pie charts; calculate percentages, ratios, and averages accurately.
Basic Computer Knowledge

Soil Science and Soil Conservation Principles
Soil texture: sand (>0.05 mm), silt (0.002–0.05 mm), clay (<0.002 mm); textural triangle classifies soils.
Soil structure: granular, blocky, prismatic, platy; good structure improves aeration, infiltration, and root growth.
Soil pH: acidic <6.5, neutral 6.5–7.5, alkaline >7.5; affects nutrient availability (N, P, K, micronutrients).
Soil organic matter (SOM): improves water holding capacity, cation exchange capacity (CEC), and microbial activity; FYM, compost, green manure.
Erosion types: water erosion (sheet, rill, gully), wind erosion; factors: rainfall erosivity, soil erodibility, slope, cover, management (USLE: A=R×K×LS×C×P).
Conservation measures: contour bunding, terracing, check dams, grassed waterways, strip cropping, mulching, afforestation, zero tillage.
Nutrient management: NPK fertilizers, integrated nutrient management (INM), biofertilizers (Rhizobium, Azotobacter, PSB), soil test based recommendations.
Soil survey and classification: alluvial, black, red, laterite, desert, mountain soils; Soil Health Card parameters (pH, EC, OC, N, P, K, micronutrients).
Agronomy, Crop Husbandry and Watershed Management
Crop seasons: Kharif (monsoon, June–Oct), Rabi (winter, Oct–Mar), Zaid (summer, Mar–Jun); Odisha mainly rice in Kharif.
Crop rotation and mixed cropping: legumes fix nitrogen; rotation breaks pest cycles; intercropping uses resources efficiently.
Seed rate, spacing, and sowing depth: vary by crop; e.g., rice 20–25 kg/ha, spacing 20×10 cm or 20×15 cm.
Irrigation methods: surface, sprinkler, drip; critical stages for rice (tillering, panicle initiation, flowering), wheat (CRI stage).
Integrated pest management (IPM): cultural, mechanical, biological, chemical; economic threshold level (ETL).
Watershed: area draining to a common point; components: ridge, slope, valley; watershed management includes soil conservation, water harvesting, and crop planning.
Water harvesting structures: farm ponds, check dams, percolation tanks, contour trenches; increase groundwater recharge.
Cropping systems: rice-rice, rice-pulses, rice-oilseeds; diversification for income and soil health.
Extension Education
Extension education: non-formal education for rural people to bring about desirable changes in knowledge, skills, and attitudes.
Teaching methods: individual (farm visit, office call), group (demonstration, method demonstration, result demonstration), mass (radio, TV, print, social media).
Extension teaching steps: identify needs, plan, execute, evaluate, and follow-up.
Adoption process: awareness, interest, evaluation, trial, adoption; innovators, early adopters, early majority, late majority, laggards.
Communication elements: sender, message, channel, receiver, feedback; barriers (physical, cultural, psychological).
Participatory approaches: PRA (Participatory Rural Appraisal), RRA (Rapid Rural Appraisal), farmer field schools (FFS), self-help groups (SHGs).
Role of extension worker: change agent, facilitator, link between research and farmers; build trust and local leadership.
Evaluation: formative and summative; indicators like adoption rate, yield increase, income change.
