Agronomy and Crop Production
Cropping intensity (%) = (total cropped area ÷ net sown area) × 100; it measures how many crops a field carries per year.
Cropping system types: sole cropping, multiple cropping, sequence cropping, intercropping, mixed cropping, relay cropping, strip cropping.
Intercropping advantage is judged by Land Equivalent Ratio (LER); LER above 1.0 means the intercrop out-yields the same land in sole crops.
Cereal-legume intercropping (e.g., maize + cowpea, pearl millet + moth bean) adds nitrogen through legume symbiosis and buffers yield risk.
Seed rate (kg/ha) = (desired plant population per ha × test weight in g) ÷ (1000 × germination fraction × purity fraction).
Crop seasons in Haryana: kharif (June–October, rice, cotton, bajra, moong), rabi (October–April, wheat, mustard, gram), zaid (summer short-duration crops).
Wheat yield components: effective tillers/m², grains per ear, and 1000-grain weight; yield (q/ha) = tillers/m² × grains/ear × test weight (g) ÷ 100,000.
Rice transplanting: 2–3 seedlings per hill, 20 × 15 cm or 20 × 10 cm spacing; puddled transplanting improves water retention and weed control.
Pulses fix nitrogen via Rhizobium; treat seed with appropriate rhizobial culture before sowing to improve nodulation in moong, gram and lentil.
Soil Science and Soil Health Management
Soil texture classes by sand, silt and clay percentage: sandy, loamy sand, sandy loam, loam, silt loam, clay loam, clay; a textural triangle converts percentages to class.
Bulk density (g/cm³) = oven-dry soil mass ÷ total soil volume; typical agricultural mineral soils range 1.1–1.6 g/cm³.
Soil pH affects nutrient availability: pH 6.0–7.5 favours most nutrients; phosphorus availability drops sharply below pH 5.5 and above pH 7.5.
Electrical conductivity (dS/m) measures salinity; soils above roughly 4 dS/m in saturation extract are saline and restrict germination of sensitive crops.
Essential plant nutrients: 17 in total - macronutrients N, P, K, Ca, Mg, S; micronutrients Fe, Mn, Zn, Cu, B, Mo, Cl, Ni.
Organic carbon below 0.5% is a low-fertility indicator; regular addition of FYM or green manure builds carbon and improves structure.
Fertilizer dose calculation: nutrient required (kg/ha) ÷ nutrient fraction in fertilizer; urea is 46% N, DAP is 18% N and 46% P₂O₅, MOP is 60% K₂O.
Soil sampling: collect from 0–15 cm depth, mix 8–10 cores in a zig-zag pattern to form a composite sample, quarter it and send about 500 g to the lab.
Saline-sodic soils respond to gypsum application followed by leaching; the gypsum requirement depends on exchangeable sodium percentage.
Plant Protection and Integrated Pest Management
IPM hierarchy: cultural, mechanical, physical, biological, botanical and chemical control; chemical control is the last resort.
Economic Threshold Level (ETL) is the pest density at which control action pays for itself; scouting at regular intervals is required to compare field counts with ETL.
Major Haryana wheat pests and diseases: yellow rust, brown rust, loose smut, termites, aphids; rice: stem borer, leaf folder, bacterial blight, blast.
Cotton pink bollworm management uses pheromone traps for monitoring, timely termination of the crop, and destruction of infested bolls and stubble.
Biological control agents: Trichogramma egg parasitoids against lepidopteran borers, Chrysoperla (green lacewing) against aphids and whiteflies, Bt formulations against caterpillars.
Pesticide label information: common name, formulation, active ingredient concentration, toxicity class (red, yellow, blue, green triangles), dose, waiting period and expiry.
Pre-harvest interval (PHI) is the minimum days between the last spray and harvest; harvesting earlier leaves illegal residues.
Fungicide groups and rotation: repeated use of a single systemic fungicide selects resistant pathogen strains, so alternate modes of action.
Weed categories: grasses, sedges and broadleaf weeds; selective herbicides kill target groups without harming the crop, non-selective ones kill all vegetation.
Horticulture and Vegetable Production
Vegetable nursery: raised beds of 10–15 cm height, solarized soil, and a 1:1:1 ratio of soil, sand and FYM is a common sowing medium.
Kharif vegetables include okra, brinjal, cucumber, bitter gourd, bottle gourd; rabi vegetables include cauliflower, cabbage, carrot, pea, tomato.
Tomato staking and pruning improve fruit quality; indeterminate types need support and regular removal of side shoots.
Nursery transplanting shock is reduced by hardening seedlings for 5–7 days and transplanting in the cool part of the day with irrigation.
Fruit tree propagation: grafting (mango, guava), budding (citrus, ber), cuttings (grape, pomegranate), layering (guava, litchi).
Vegetable seed rate examples: tomato 400–500 g/ha, okra 8–10 kg/ha, onion 8–10 kg/ha; excess seed causes dense stands and disease.
Protected cultivation uses polyhouse or shade net to control temperature, humidity and pest entry; drip plus fertigation is standard inside.
Post-harvest handling: harvest at correct maturity, grade, pre-cool, and avoid rough handling to reduce losses in perishable vegetables.
Animal Husbandry and Livestock Management
Cattle body temperature is about 38.5 °C; a rise above 39.5 °C with off-feed and reduced rumination signals illness.
Rumen pH in a healthy animal is around 6.5–7.0; sudden feeding of high-concentrate diets lowers it and causes acidosis.
Colostrum should be fed within the first hour after birth, about 10% of body weight in the first 24 hours, to transfer passive immunity.
Heat detection in cattle: standing to be mounted is the primary sign; the estrus cycle averages 21 days and heat lasts 12–18 hours.
Gestation periods: cattle about 280 days, buffalo about 310 days, goat about 150 days, sheep about 148 days.
Vaccination schedule basics: FMD, HS, BQ and brucellosis are major preventable diseases in Haryana cattle and buffalo herds.
Balanced ration must contain energy, protein, minerals and vitamins; green fodder plus dry fodder plus concentrate in a defined ratio.
Milking hygiene: wash the udder, use clean utensils, discard foremilk, and practise post-milking teat dipping to prevent mastitis.
Farm Machinery, Tools and Equipment
Tractor power take-off (PTO) standard speeds are 540 and 1000 rpm; implement matching depends on PTO power, not engine power alone.
Draft requirement of tillage tools rises with depth and soil moisture; operating at too high a moisture content smears the soil and increases draft.
Field capacity measures the fraction of time a machine is productive; field efficiency (%) = (effective field capacity ÷ theoretical field capacity) × 100.
Effective field capacity (ha/h) = (implement width in m × speed in km/h × field efficiency) ÷ 10.
Common tillage implements: mouldboard plough, disc plough, cultivator, harrow, rotavator, leveller; each suited to different depth and soil conditions.
Sprayer calibration: nozzle discharge test, walking speed and swath width determine litres per hectare; incorrect calibration causes under- or over-dosing.
Seed drill calibration is done by turning the ground wheel a set number of revolutions and weighing the seed dropped.
Safety: PTO shafts must have intact guards; never step over a rotating shaft or clean a machine while it is running.
Irrigation and Water Management
Irrigation water requirement = crop evapotranspiration − effective rainfall; scheduling by soil moisture depletion avoids both stress and wastage.
Soil moisture tension measured with tensiometers; irrigation is triggered at a set tension that depends on soil texture and crop sensitivity.
Drip irrigation saves water by delivering directly to the root zone; emitter discharge is rated in litres per hour and must match crop demand.
Sprinkler irrigation suits undulating land and close-growing crops; runoff and wind drift reduce uniformity.
Flood irrigation is common in rice; field-to-field water loss and percolation are the main inefficiencies and can be reduced by laser levelling.
Critical irrigation stages: wheat at crown root initiation and flowering, rice at panicle initiation, mustard at flowering and pod formation.
Water use efficiency (kg/m³) = crop yield ÷ water applied; it rises with drip, mulching and timely irrigation.
Conjunctive use of canal and tube well water, and rainwater harvesting in farm ponds, buffer against canal rotation gaps.
Agricultural Economics
Gross income = yield × price; net income = gross income − total cost of cultivation.
Cost concepts: fixed cost (land rent, depreciation, interest) does not vary with output; variable cost (seed, fertilizer, labour, irrigation) does.
Benefit-cost ratio = total returns ÷ total cost; a ratio above 1 indicates a profitable enterprise.
Farm size classes in India: marginal (<1 ha), small (1–2 ha), semi-medium (2–4 ha), medium (4–10 ha), large (>10 ha).
Cost of production per quintal = total cost of cultivation ÷ total yield in quintals.
Labour requirement is expressed in man-days per hectare; mechanization reduces peak labour demand and shifts cost toward machinery.
Marginal returns: an input should be increased until the value of the additional output equals the cost of the additional input.
Crop insurance and minimum support price influence the risk-adjusted profitability of a cropping plan.
Marketing and Entrepreneurship
Marketing channels: producer → village trader → wholesaler → retailer → consumer; each intermediary adds margin and reduces the producer share.
Marketable surplus = production − family consumption − seed and other on-farm retention.
Price spread = consumer price − producer price; it measures total marketing cost plus margins in the chain.
Grading and standardization (AGMARK) improve price realization; sorting by size, colour and quality attracts better buyers.
Value addition through cleaning, grading, packaging, processing or branding raises the unit value of produce.
Direct marketing options include farmer producer organizations (FPOs), e-NAM and direct supply to processors or retailers.
Entrepreneurship basics: identify a demand gap, estimate cost and revenue, arrange finance, and keep simple records of cash flow.
Warehouse receipts allow farmers to store produce and borrow against it instead of distress selling at harvest.
Agricultural Extension and Communication
Extension methods: individual (farm visit, telephone call), group (demonstration, field day, farmer interest group) and mass (radio, TV, print, social media).
The adoption curve classifies farmers as innovators, early adopters, early majority, late majority and laggards.
A field demonstration is most effective when it compares a new practice with the local practice on the same field and season.
Communication elements: sender, message, channel, receiver and feedback; feedback confirms whether the message was understood.
Participatory approaches such as farmer field schools build local decision-making rather than one-way instruction.
Baseline survey data (crop, area, yield, income) is needed to measure the impact of an extension programme.
Kisan Call Centre and agricultural extension portals give farmers direct access to expert advice in local languages.
Barriers to adoption include cost, risk perception, lack of inputs, and low literacy; extension messages must address these.
