Amazing facts in Agricultural Science

Cows technically have one stomach, not four. However, a cow's stomach has four compartments. These are: rumen, reticulum, omasum and abomasum

Peanuts are legumes and not nuts

Although plants neither see nor hear, they can recognize their siblings and even give them preferential treatments

Squirrels do plant more trees (through their actions) than an average human in their lifetime. They often hide their acorns and nuts underground and forget about them

Cows have got the ability to walk up stairs, but not down stairs

A group of cows is called a team, drove or herd.

People just prefer to call them herd

Notable points in Agricultural Science

Below are characteristics of gymnosperms:

  1. Their seeds have cones that protect them.

  2. Sepals and petals aren't present in their cones.

  3. Stigma and style are absent.

  4. They do not produce fruits. Only seeds are formed.

  5. Companion cells are absent.

  6. Sporophyll form the cones.

  7. Anther and filament are absent.

  8. The ovules are not present in the ovary.

  9. Gymnosperms do not possess flowers.

  10. Please read on the anatomical differences between gymnosperms and angiosperms here

The flower is the reproductive organ in plants' sexual reproduction. In order to achieve a successful sexual propagation or reproduction in plants, the floral parts of the flower are utilized.

The floral parts of a flower consists of the followings:

  1. Sepals

  2. Petals

  3. Stamen

  4. Carpel

The stamen is male portion of a plant. It consists of the anther and filament.

The carpel (or pistil) is the female portion of the plant. It consists of the stigma, style and ovary.

An organism will be considered a pest if it does one of the followings:

  • Attack crops and eat its seeds, roots, stem, leaves and flowers. Examples are locust and grasshoppers.

  • Cause damage to stored food, fruits or other agricultural produce. Some may even urinate or deaficate on these products. Examples are rodents, cockroaches and mice.

  • Attack and kill farm animals like goats, sheep and cattle. Examples are foxes, wild cats and snakes.

  • Act as disease vectors. A vector is an organism that carries parasite and other disease causing organisms, without being affected; but when they introduce the parasites into their host, such host becomes infected with disease. Examples of vectors are rodents and mosquitoes.

Below are the classification of crops based on their uses:

  • Oil crops

  • Vegetable crops

  • Latex crops

  • Drug and Medicinal crops

  • Beverage crops

  • Fibre crops

  • Fruit crops

  • Root and Tubers

  • Legumes

  • Spices

  • Cereals

All crops are plants but not all plants are crops. Below are some instances:

  • Weeds are considered as plants, not crops.

  • Parasitic plants are not necessarily crops. Examples of parasitic plants include mistletoe, corpse flower and striga.

  • Carnivorous or insectivorous plants are not necessarily crops. Examples are sundew, venus flytrap and pitcher plant. The image below shows a carnivorous plant (venus flytrap).
