Class 8 Crop Production and Management Notes

 

Class – 8th

Crop Production and Management

 

  • All living organisms require food.
  • The energy from food is utilised by an organism for carrying out its various life processes such as digestion, respiration, and excretion.
  • Plants can make their food themselves but animals including humans cannot.
  • We get our food from plants or animals, or both.
Plants of the same kind that are grown and cultivated as a source of food in a large cultivable land is called a crop.
Kya hum koi bhi crop kabhi bhi uga sakte hai? Nahi, har crop different hai jisko different weather conditions different soil and nutrients required hai.
Types of Crops
Rabi Crop
Crops which are grown in the winter season (from October to March) are called Rabi crops.
For Example: Wheat, Gram, Pea, Mustard, and Linseed.
Kharif Crop
Crops which are sown in the rainy season (from July to October) are called Kharif crops.
For Example: Paddy, maize, soyabean, groundnut, and cotton.
Zaid Crops (or Summer Crops)
The crops which are grown in the summer season are called zaid crops.
For Example : Moong, muskmelon, watermelon, cucumber, gourd and bitter gourd.
Cultivation of crops
  • Soil Preparation:It involves loosening and tilling of the soil (i.e., ploughing and watering).
Selection of Seed – Quality of the Seeds
  • The quality of the seed is an important factor that determines the crop yield.
  • The selection of good seeds is done by putting the seeds in water.
  • The dead and damaged seeds become hollow and float on water, whereas the good seeds sink.
  • Sowing:Sowing is the process of putting seeds in the soil.
  • Adding Manure and Fertilisers:The substances, which are added to the soil in the form of nutrients to improve the production of the crops and fertility of the soil are called manure and fertilisers.
  • Irrigation:Supply of water to crops at appropriate intervals is called irrigation.
  • Protection from Weeds:Weeds are the unwanted plants that grow along with the crops. Its removal is a must for the better growth of the crops. These can be controlled by spraying certain chemicals, called weedicides, like 2, 4-D.
  • Harvesting:The cutting of the crop after it is mature is called harvesting.
  • Storage: If the crop grains are to be kept for a longer time, they should be safe from moisture, insects, and rats.

Perimeter and Area Worksheet class 5

Welcome to this comprehensive worksheet designed to aid CBSE Class 5 students in mastering the concepts of perimeter and area, pivotal aspects of their mathematics curriculum.

Understanding Perimeter and Area:

Introduction:

Have you ever wondered how much fencing you would need to enclose your dream garden? Or how much carpet you would need to cover your bedroom floor? Well, the answers to these questions lie in two important concepts: perimeter and area! In this fun and engaging worksheet, we will explore these concepts and learn how to use them to measure different shapes.

What is Perimeter?

Imagine you want to walk around the edge of a playground. The total distance you cover is called the perimeter. In simpler words, the perimeter is the “fence” around a shape.

How to Calculate Perimeter:

The perimeter of a shape is the sum of the lengths of all its sides. To find the perimeter, you simply add up the lengths of all the sides!

What is Area?

The area of a shape tells you how much space it covers on a flat surface. Imagine filling a shape with sand or tiles. The amount of sand or tiles you use represents the area.

How to Calculate Area:

The area of a shape depends on its specific shape. For example, the area of a rectangle is calculated by multiplying the length by the width. We will explore different formulas for calculating the area of various shapes in this worksheet.

Practice Worksheet

  1. What is the perimeter of a square with a side length of 8 cm?
    a. 16 cm
    b. 24 cm
    c. 32 cm
    d. 64 cm
  2. The area of a rectangle is 20 cm². If its width is 4 cm, what is its length?
    a. 2 cm
    b. 5 cm
    c. 8 cm
    d. 10 cm
  3. Which shape has the greatest area given a fixed perimeter of 20 cm?
    a. Square
    b. Rectangle (length 8 cm, width 2 cm)
    c. Triangle with equal sides
    d. Circle
  4. What is the perimeter of a square with a side length of 6 units?
    a. 12 units
    b. 18 units
    c. 24 units
    d. 36 units
  5. If the perimeter of a rectangle is 30 cm and its length is 8 cm, what is its width?
    a. 5 cm
    b. 6 cm
    c. 7 cm
    d. 8 cm
  6. If the perimeter of a square garden is 28 meters, what is the length of each side?

 

  1. Compare the area of a square with a side length of 6 meters to the area of a rectangle with dimensions 4 meters by 9 meters. Which shape has a larger area and by how much?

Real-life Application:

  1. Imagine a scenario where a farmer needs to fence a rectangular pasture with a length of 20 meters and a width of 15 meters. Calculate:
  • The total length of fencing required
  • The area of the pasture
  1. A farmer wants to fence in a rectangular field with a length of 40 meters and a width of 30 meters. How much fencing material does the farmer need in total?

 

Answer Key

  1. c
  2. b
  3. b
  4. c) 24 cm
  5. c) 7 cm
  6. 7 cm
  8. i) 70 m ii) 300m2
  9. 140 cm

 

Through this worksheet, CBSE Class 5 students have engaged with a range of questions focused on perimeter and area. By solving multiple-choice questions, short-answer questions, and applying concepts to real-life scenarios, students have strengthened their understanding of these fundamental mathematical principles. Practicing such exercises will not only enhance their academic performance but also cultivate critical thinking and problem-solving skills essential for future success in mathematics and beyond.
