Which of the following sentence is/are correct about crop rotation? 1. Crop rotation helps return nutrients to the soil without synthetic inputs. 2. Crop rotation is the pratice of planting different crop sequentially on the same plot of land to improve soil health. 3. Crop rotation deteriorates the soil structure as same nutrients are used time and time again. Correct Answer 1 and 2

The correct answer is 1 and 2.

Key Points

  • Crop Rotation
    • Crop rotation is the practice of growing a series of different types of crops in the same area across a sequence of growing seasons. Hence statement 2 is correct.
    • It reduces reliance on one set of nutrients, pest and weed pressure, and the probability of developing resistant pests and weeds.
    • Crop rotation involves planting a sequence of different kinds of crops in a location over a number of seasons.
    • Rotating crops helps maintain or improve soil health and maintain or increase the productivity of the farm over time. Hence statement 1 is correct.
    • Crop rotations can improve soil structure and organic matter, which reduces erosion and increases farm system resilience. Hence statement 3 is incorrect.
    • A diverse crop rotation gives the soil microbes different food sources, which ultimately makes soil healthier.

Additional Information

  • Intercropping:
    • Examples- Planting alternating rows of maize and beans, or growing a cover crop in between the cereal rows.
    • Intercropping means growing two or more crops in the same field at the same time.
  • Sequential Cropping:
    • Example- Planting maize in the long rains, then beans during the short rains.
    • Sequential Cropping involves growing two crops in the same field, one after the other in the same year.
  • Monocropping:
    • Example- Planting Wheat year after year in the same field.
    • Monocropping is when the field is used to grow only one crop season after season.

Read the following passage and answer the item that follows. Your answers to this item should be based on the passage only. Many farmers use synthetic pesticides to kill infesting insects. The consumption of pesticides in some of the developed countries is touching 3000 grams/hectare. Unfortunately, there are reports that these compounds possess inherent toxicities that endanger the health of the farm operators, consumers and the environment. Synthetic pesticides are generally persistent in environment. Entering in food chain they destroy the microbial diversity and cause ecological imbalance. Their indiscriminate use has resulted in development of resistance among insects to insecticides, upsetting of balance in nature and resources of treated populations. Natural pest control using the botanical pesticides is safer to the user and the environment because they break down into harmless compounds within hours or days in the presence of sunlight. Plants with pesticidal properties have been in nature for millions of years without any ill or adverse effects on the ecosystem. They are easily decomposed by many microbes common in most soils. They help in the maintenance of biological diversity of predators and human health hazards. Botanical pesticides formulated from plants are biodegradable and their use in crop protection is a practical sustainable alternative. On the basis of the above passage, the following assumptions have been made: 1. Synthetic pesticides should never be used in modern agriculture. 2. One of the aims of sustainable agriculture is to ensure minimal ecological imbalance. 3. Botanical pesticides are more effective as compared to synthetic pesticides. Which of the assumptions given above is/are correct?
The selling price of plot is directly proportional to the square of area of plot in m2. If the cost price of square shaped plot is Rs. 50000 and the profit percent of a dealer is 25% on selling square shaped plot then find the cost price of rectangular shaped plot if the dealer gains 50% on selling of rectangular plot where the length and breadth of rectangular plot is 30 m and 20 m while the side length of square plot is 20 m.

We have forgotten that health really means to enable a person to do his work and do it well. A lot of modern medicine, and this includes many patients as well as many physicians, pay very little attention to health but very much attention to those who imagine they are ill. Our great concern with health is shown by the medical columns in newspapers, the health articles in popular magazines and the popularity of television programmes and all those books on medicine. We talk about health all the time. Yet for the most part the only result is more people with imaginary illness. A healthy man should not be wasting time talking about health : he should be using health for work.

A rectangular plot has a concrete path running in the middle of the plot parallel to the breadth of the plot. The rest of the plot is used as a lawn which has an area of 420 sq. m. If the width of the path is 4 m and the length of the plot is greater than its breadth by 36 m, what is the area of the rectangular plot? 
A big rectangular plot of area 4320 m2 is divided into 3 square-shaped smaller plots by fencing parallel to the smaller side of the plot. However some area of land was still left as a square could not be formed. So, 3 more square-shaped plots were formed by fencing parallel to the longer side of the original plot such that no area of the plot was left surplus. What are the dimensions of the original plot ?
