\n<\/h2>\n

\u00a0A crop is a plant which is cultivated by man for some beneficial purposes. Crops can be classified based on (i) life cycle (ii)morphology (iii) uses. <\/p>\n

\u00a0<\/p>\n

CLASSIFICATION BASED ON LIFE CYCLE
\n<\/h2>\n

The life cycle of a crop is the period from planting of seed to maturity of the crop. Based on life cycle, crops can be grouped into three: – <\/p>\n

    \n
  1. \n
    ANNUAL CROPS: – These are crops which grow and complete their life cycle within a year e. g. cotton, cowpea, yam, rice etc.\n<\/div>\n<\/li>\n
  2. \n
    BIENNIAL CROPS: – These are crops which grow and complete their life cycle within as year e. g. cassava, pepper, onions, carrot, ginger etc.\n<\/div>\n<\/li>\n
  3. \n
    PERENNIAL CROPS: – These are crops which grow and complete their life cycle in more than two years e. g. banana, orange, cocoa, coconut etc.\n<\/div>\n<\/li>\n<\/ol>\n

      \u00a0<\/p>\n

      CLASSIFICATION BASED ON MORPHOLOGY
      \n<\/h2>\n

      On the basis of morphology i.e. structure (form and shape of a plant), crops are classified as: <\/p>\n

        \n
      1. \n
        MONOCOTYLEDONOUS CROPS: These are crops which bear seeds that have only one seed leaf (cotyledon). Their leaves have parallel veins and they have fibrous root system. Examples include:maize, rice, millet, wheat,oil palm, grasses, etc.\n<\/div>\n<\/li>\n
      2. \n
        DICOTYLEDONOUS CROPS: These are crops which bear seeds that have two seed leaves or cotyledons. They possess leaves with net veins and tap root system. Example include: mango, orange, cowpea, groundnut, kola nut, pepper, etc.\n<\/div>\n

        EVALUATION QUESTIONS <\/p>\n

          \n
        1. \n
          State five characteristics of monocot crops and three examples.\n<\/div>\n<\/li>\n
        2. \n
          State five characteristics of dicot crops and three examples.\n<\/div>\n<\/li>\n<\/ol>\n

          CLASSIFICATION BASED ON USES
          \n<\/h2>\n
            \n
          1. \n
            CEREALS: – Crops grown for their grains or seeds which are rich in carbohydrates. They belong to the grass family e. g. maize, millet, rice, wheat, oat, barley, guinea corn etc.\n<\/div>\n<\/li>\n
          2. \n
            LEGUMES (PULSES): – These are crops grown for their seeds or grains which are rich in proteins e. g. cowpea, groundnut, soya beans, pigeon peas etc.\n<\/div>\n<\/li>\n
          3. \n
            ROOTS AND TUBERS: – These crops produce tubers under the ground that are rich in carbohydrates e. g. cassava, yam, potato, carrot, etc.\n<\/div>\n<\/li>\n
          4. \n
            VEGETABLES: These are crops grown for their leaves, fruits, or roots which are rich in vitamins and minerals e. g. tomato, lettuce, okro, amaranthus, cabbage etc.\n<\/div>\n<\/li>\n
          5. \n
            SPICES: – These crops are also rich in vitamins and minerals and are rich in food flavours\n<\/div>\n

            e. g. pepper, ginger, garlic, onions, curry etc.\n<\/li>\n

          6. \n
            BEVERAGE CROPS: – They are used in making food drinks e. g. cocoa, coffee, tea, kola nut etc.\n<\/div>\n<\/li>\n
          7. \n
            FRUIT CROPS: – These are plants which bears edible fruits that are rich in vitamins and minerals e. g. oranges, cashew, guava, water melon etc.\n<\/div>\n<\/li>\n
          8. \n
            OIL CROPS: – These are crops which produce edible oil when processed e. g. cotton seed, coconut, oil palm, groundnut, shear butter etc.\n<\/div>\n<\/li>\n
          9. \n
            LATEX CROPS: – They produce fluid called latex which when processed served as raw materials for making tyres, plastics, foam etc. Example is rubber tree.\n<\/div>\n<\/li>\n
          10. \n
            FIBRE CROPS: – They produce fibres used for making clothes, ropes, sacs etc. Examples include cotton, sisal, jute, hemp, kenaf etc.\n<\/div>\n<\/li>\n
          11. \n
            DRUG PLANTS: – Crops grown for medicinal purposes e. g. tobacco, neem, Indian hemp etc.\n<\/div>\n<\/li>\n
