Maharashtra HSC Crop Science (Vocational) study guide
Maharashtra HSC Crop Science (Vocational) · Work through your exam, one topic at a time.
Crop Science is one of the vocational subjects offered at the Higher Secondary Certificate (HSC) level by the Maharashtra State Board of Secondary and Higher Secondary Education (MSBSHSE). It is designed for Class XI–XII students who want a science-linked, practice-oriented route into agriculture rather than a purely academic one. The Maharashtra HSC Crop Science (Vocational) study guide has 11 sections and about 4,006 words.
01Introduction to Crop Science and Crop Classification
Questions here check whether you can define a crop and place any Maharashtra crop into the right class by season, use, life cycle, root system, photosynthetic pathway and soil-nutrient behaviour. Expect short definitions plus applied classification of crops such as soybean, jowar, sugarcane, tur and cotton.
368 words, about 2 min02Soil Science and Soil Fertility Management
Soil profile and texture, the soil types of Maharashtra, soil reaction and salinity, organic carbon, cation exchange and the interpretation of a soil test report. Maharashtra soils: black cotton soil (vertisol) dominates the Deccan - high clay, high water-holding capacity, low infiltration, self-mulching, pH 7.5–8.5; laterite and red soils on the Konkan and eastern hills, often acidic and low in bases; alluvial soils in river valleys and coastal plains; saline-sodic patches in rain-shadow and irrigated commands.
376 words, about 2 min03Plant Nutrition
The essential elements, criteria of essentiality, functions, deficiency and toxicity symptoms, nutrient mobility in the plant, antagonism and the choice between soil and foliar application. Seventeen elements are essential: carbon, hydrogen, oxygen, nitrogen, phosphorus, potassium, calcium, magnesium and sulphur as macronutrients; iron, manganese, zinc, copper, boron, molybdenum, chlorine and nickel as micronutrients.
412 words, about 2 min04Manures and Fertilizers
Organic manures, biofertilizers, fertilizer grades, straight and complex fertilizers, and the arithmetic of converting a recommended nutrient dose into bags of fertilizer. Bulky organic manures: farmyard manure (about 0.5% N, 0.2% P2O5, 0.5% K2O), compost, vermicompost, green manures (dhaincha, sunhemp), oil cakes and poultry manure.
365 words, about 2 min05Crop Production Practices and Agronomic Operations
The operation sequence from land preparation to harvest - tillage, seed rate, sowing method, spacing, plant population, interculture and cropping systems. Tillage: primary tillage (plough) breaks the hardpan and inverts soil; secondary tillage (harrow, cultivator, rotavator, leveller) produces a fine, level seedbed.
337 words, about 2 min06Irrigation, Water Management and Drainage
Water requirement, irrigation scheduling, methods of application, irrigation water quality, drainage and management of waterlogged or saline soils. Water requirement = consumptive use (transpiration plus evaporation) plus conveyance and application losses.
361 words, about 2 min07Crop Protection: Weeds, Insect Pests and Diseases
Identification and management of weeds, insect pests and diseases, integrated pest management, economic thresholds, herbicide selectivity and pesticide safety. Weeds are classified by life cycle (annual, biennial, perennial), morphology (grassy, broad-leaved, sedge) and habitat.
358 words, about 2 min08Farm Machinery, Implements and Tools
Identification and selection of tools, implements and machines, primary versus secondary tillage equipment, sowing and plant-protection machines, tractor–implement matching, calibration and maintenance. Primary tillage: mouldboard plough (inverts soil, buries residue, high draft), disc plough (works in hard, dry or sticky soils) and chisel plough (breaks hardpan without inverting).
366 words, about 2 min09Seed Technology and Planting Material
Seed quality attributes, the seed certification chain, testing methods, seed treatment, seed-rate calculation, seed storage and the planting material used for vegetatively propagated crops. Four quality pillars: genetic (trueness to type), physical (purity and freedom from inert matter and weed seed), physiological (germination and vigour) and sanitary (free from seed-borne pathogens and insects).
335 words, about 2 min10Post-Harvest Handling, Storage and Marketing
Harvest maturity, threshing and cleaning, grading, curing and drying, safe storage, storage pests, value addition and the marketing routes open to a Maharashtra farmer. Maturity indices: grain moisture, colour change, days to maturity and leaf drop; for fruits, total soluble solids, firmness and peel colour.
353 words, about 2 min11Entrepreneurship, Farm Management and Occupational Safety
Farm business concepts, costs and returns, budgeting and break-even, agri-enterprise opportunities and support schemes, farm records, and health and safety at work. Costs: variable costs change with area or enterprise (seed, fertilizer, casual labour, fuel); fixed costs do not (land revenue, depreciation, permanent labour, interest on land).
