    Study Notes

    Crop Classification

    • Over 600 plant species are cultivated, but only 15 are considered economically significant.
    • Botanical Classification: Plants are categorized based on their genus and species, using a binomial system.
      • Monocotyledons: Have a single cotyledon (seed leaf) in the seed.
        • Gramineae: Wheat, barley, rice, maize, oats, sugarcane, sorghum, ryegrass, Sudan grass.
        • Liliaceae: Onion, garlic.
      • Dicotyledons: Have two cotyledons in the seed.
        • Leguminosae: Fababean, lupine, chickpea, lentil, fenugreek, Egyptian clover, alfalfa, soybean, peanut, grass pea, castor bean, red clover, white clover.
        • Malvaceae: Cotton.
        • Linaceae: Flax.
        • Solanaceae: Potato, tomato, tobacco.
        • Pedaliaceae: Sesame.
        • Composite: Sunflower, safflower.
    • Agronomic Classification: Categorizes crops based on their agricultural use.
      • Cereals/Grain Crops: Grasses grown for their edible seeds (e.g., wheat, oats, barley, rye, rice, maize, grain sorghum).
      • Legumes: Grown for their seeds (e.g., fababean, peanut, fenugreek, lupine, cowpea, soybean, chickpea, lentil).
      • Sugar Crops: Sugar beet, sugarcane.
      • Oil Crops: Flax, soybean, peanut, sunflower, safflower, sesame, castor bean, rape.
      • Fiber Crops: Cotton, flax, jute, sisal, ramie.
      • Fodder Crops: Alfalfa, Egyptian clover, sorghum, Sudan grass, grass pea, lablab, Napier grass, millet, white clover, red clover.
      • Rubber Crops: Para rubber, Castilla rubber, guayule.
      • Tuber Crops: Potatoes, Jerusalem artichoke.
      • Root Crops: Sweet potatoes, sugar beet.
      • Medical Plants: Castor bean and others.
      • Stimulants: Tobacco, tea, coffee.
    • Special-Purpose Classification: Focuses on specific agricultural uses.
      • Catch/Emergency Crops: Quick-growing substitutes for failed crops (e.g., toria, fodder, rye, millet, clover).
      • Cash Crops: Grown for generating income (e.g., sugarcane, cotton).
      • Cover Crops: Protect soil and prevent erosion (e.g., green manures, pulses, clover).
      • Green Manure Crops: Ploughed into soil to improve its properties (e.g., Egyptian clover, lupine, cowpea).
      • Companion Crops: Intercropped with other crops for mutual benefit (e.g., mustard in sugarcane, wheat in sugarcane, onion and garlic in cotton, soybean in maize).
      • Silage Crops: Preserved for feed through fermentation (e.g., corn, sorghum, forage grasses, legumes).
    • Classification According to Life Span: Based on how long a crop lives.
      • Annual Crops: Complete their life cycle in one growing season (e.g., wheat, barley, rice, maize, sorghum, safflower).
      • Biennial Crops: Complete their life cycle in two seasons, with vegetative growth in the first and flowering/seed production in the second (e.g., onion, sugar beet).
      • Perennial Crops: Live for more than two years, potentially producing seeds annually (e.g., sugarcane, alfalfa).
    • Classification According to Root Depth:
      • Shallow Root Crops: Root system extends up to one meter deep (e.g., wheat, barley, rye).
      • Intermediate Root Crops: Root system extends from 1 to 1.5 meters deep (e.g., fababean, sugar beet).
      • Deep Root Crops: Root system extends deeper than 1.5 meters (e.g., alfalfa).
    • Classification According to Growing Season: Categorizes crops based on the time of year they are planted and harvested.
      • Winter Crops: Planted in fall and harvested in spring (e.g., wheat, barley, fababean, lentil, chickpea).
      • Summer Crops: Planted in spring and harvested in summer (e.g., maize, mungbean, urdbean).
      • Rainy Season Crops: Planted during rainy season and harvested in fall (e.g., rice, cotton, wheat, mungbean).
    • Kharif Crops: Planted and harvested during the monsoon season (e.g., paddy, maize, soybean, sorghum, groundnut, cotton, urd).
    • Classification According to Mode of Pollination:
      • Naturally Self-Pollinated Crops: Pollination occurs within the same plant (e.g., rice, wheat, okra, tobacco, tomato).
      • Naturally Cross-Pollinated Crops: Pollination occurs between different plants (e.g., maize, many grasses, avocado, grape, mango).
      • Both Self- and Cross-Pollinated Crops: Pollination can occur both within and between plants (e.g., cotton, sorghum).
    • Classification According to Taxonomy: Based on plant families.
      • Asteraceae/Composite: Sunflower, safflower, niger.
      • Cruciferae: Mustard, radish, cabbage, cauliflower.
      • Cucurbitaceae: Bottle gourd, bitter gourd, pumpkin.
      • Chenopodiaceae: Sugar beet, beet, spinach.
      • Euphorbiaceae: Castor, tapioca.
      • Malvaceae: Cotton, ladyfinger, rosette.
      • Papilionaceae/Leguminosae: Pea, gram, arhar, groundnut, berseem, lathyrus, sunhemp, lucerne, urd, moong, lentil, soybean.
      • Linaceae: Linseed.
      • Pedaliaceae: Sesame (til).
      • Poaceae/Graminae: Cereals, millets, grasses, sugarcane, napier, oat.
      • Polygonaceae: Buckwheat.
      • Solanaceae: Potato, tobacco, tomato, chili, brinjal.
    • Classification Based on Root System:
      • Tap Root System: Main root grows deep into the soil (e.g., tur, grape, cotton).
      • Adventitious/Fiber Rooted: Shallow, spreading root system (e.g., cereal crops, wheat, rice).
    • Classification Based on the Number of Cotyledons:
      • Monocots/Monocotyledons: Have one cotyledon (e.g., all cereals and millets).
      • Dicots/Dicotyledonous: Have two cotyledons (e.g., all legumes and pulses).
    • Classification Based on Climate:
      • Tropical: Grow well in warm and hot climates (e.g., rice, sugarcane, jowar).
      • Temperate: Grow well in cool climates (e.g., wheat, oats, gram, potato).
    • Classification Based on Cultural Method/Water:
      • Rainfed: Rely solely on rainwater (e.g., jowar, bajara, mung).
      • Irrigated Crops: Need supplementary irrigation (e.g., chili, sugarcane, banana, papaya).
    • Classification Based on Economic Importance:
      • Cash Crops: Grown for generating income (e.g., sugarcane, cotton).
      • Food Crops: Grown for food and fodder (e.g., jowar, wheat, rice).
    • Classification Based on Photoperiod: Based on the length of daylight required for flowering.
      • Short-Day Plants: Flower when days are shorter than a critical threshold (e.g., rice, jowar, green gram, black gram).
      • Long-Day Plants: Flower when days are longer than a critical threshold (e.g., wheat, barley).
      • Day-Neutral Plants: Photoperiod has little effect on flowering (e.g., cotton, sunflower).
