NCERT Class 9 Kaushal Vikas Chapter 1 Textbook Solutions

Section 1.1 Introduction Questions & Solutions

Q1. PORTFOLIO: Select any product that you can trace back to agricultural practices. Find out (you can do an Internet search or ask different stakeholders, including vegetable sellers) the price of the raw product/produce sold by a farmer and the cost at which it is sold. What is the price difference? Find out why the value of the raw product/produce has increased.
Answer:
Product Selected: Wheat flour (atta).
Price of Raw Produce (Farmer’s Price at Farm/Mandi): ₹20 per kg.
Retail Price at Supermarket: ₹50 per kg.
Price Difference: ₹30 per kg.
Reasons for Value Increase: According to the chapter, the cost of agricultural produce increases as it travels further, is processed further, or is packaged differently. Value is added at each stage due to:
1. Post-harvest handling: Adds 15 – 20 per cent value for cleaning, sorting, and storage (refrigeration or warehouse rent).
2. Processing: Adds 30 – 50 per cent value for grinding wheat grains into flour in processing mills.
3. Marketing and Distribution: Adds 15 – 20 per cent value for transport, packaging, and retail sales.
4. Research and Seed Costs:* If hybrid seeds are used, the initial cost increases by 20 – 400 per cent to cover research costs by scientists.

Section 1.2 Agro-climatic relationship Questions & Solutions

Q1. CHECK YOUR UNDERSTANDING: Find out what kind of data farmers use in the region your school is located in. Why is this useful for them?
Answer: Farmers in our region use meteorological data (weather observations) provided by the India Meteorological Department (IMD) and Agrotechnological Advisory Services (AAS). This data is accessed through SMS alerts, All India Radio, Doordarshan, community radio, mobile apps like Bharat-VISTAAR, Kisan Portal, Krishi Vigyan Kendra (KVK), and Gramin Krishi Mausam Sewa (GKMS) at the Panchayat level.

This data is useful for farmers because:
1. It helps them plan crops across the kharif (monsoon cropping season), rabi (winter cropping season), and summer seasons based on temperature, precipitation (rainfall and snowfall), relative humidity, and wind speed/direction.
2. It guides daily farming decisions regarding crop selection, sowing, harvesting, and irrigation scheduling.
3. Weather warnings help protect standing crops from sudden heavy rains, floods, frost, or physical damage caused by strong winds.
4. IMD forecasts help predict outbreaks of livestock diseases, allowing timely prevention or treatment.

Q2. TASK: Make your own Meteorological Lab — Build a simple meteorology observatory in your school with a (i) simple rain gauge, (ii) dry-wet bulb thermometer and (iii) wind vane. Follow the steps in Figures 1.3 – 1.5 using the materials suggested. You can always substitute the materials if you wish; please consult your teacher/an expert before doing so. Use your observatory to track rainfall, temperature (including the average and range of temperature) and wind direction. You should collect and analyse the data over three months, that is, the duration of the time you are doing this work. You can also create a weather bulletin board for farmers in your region.
Answer:
Procedure and Setup:
1. Rain Gauge: Cut off the top 1/3rd of a transparent plastic bottle to make an inverted funnel placed inside the bottle. Attach a measuring scale on the outside using tape and place it in an open area at a height. Measure collected rainwater depth in mm.
2. Dry-Wet Bulb Thermometer: Attach two thermometers to a plastic bottle, wrapping wet cotton gauze around the bulb of one (wet bulb). Spin the setup using a thread attached to the top for 1 minute. The dry bulb shows actual air temperature, while the wet bulb shows a lower temperature due to evaporation cooling. Use the reading difference to find humidity (a small difference indicates humid air; a large difference indicates dry air).
3. Wind Vane: Cut a cardboard disc, mark the four cardinal directions (North, East, West, South), and insert a pencil through the center. Attach a cardboard arrow to the pencil eraser using a pin so it rotates freely in the wind to show wind direction.
Model Observatory Record:
Duration: 3 months (July to September).
Temperature Range: 20°C to 34°C; Average Temperature: 27°C.
Total Rainfall Tracked: 145 mm.
Predominant Wind Direction: South-West.
Weather Bulletin Board:* Displayed weekly temperature averages, rainfall depth, and wind advisories at the school gate for local gardeners and farmers.

Q3. PORTFOLIO: Keep a record of data you have collected over a period of time with your DIY meteorological laboratory and share it with a farmer/gardener. Record their feedback.
Answer:
Model Data Log:
Monitoring Period: July (4 weeks).
Recorded Observations: Total rainfall = 82 mm; Daily temperature range = 22°C to 33°C; High relative humidity recorded on dry-wet bulb thermometer; Primary wind direction = West.
Gardener/Farmer Feedback:
* The local community gardener reviewed our daily weather log and shared: “Tracking humidity and daily rainfall helped us avoid over-watering our vegetable beds during humid mornings. Knowing the wind direction also helped us schedule pesticide spraying safely without wind drift.”

Section 1.3 Processes related to agricultural practices Questions & Solutions

Q1. TASK: Soil sample collection — To carry out these tests, soil can be collected from your own garden or nearby fields. The process of sample collection is very important to get good results. Take soil from different spots, for example, from a sandy area, organic pit and water channel, and mix the samples, as soil quality can vary even within a small area. Avoid shady areas (like under trees) and places, where fertilisers are stored in the field. Remove stones, leaves and other debris. Dry the soil in sunlight for a few hours. Crush clumps and sieve the mixture to get fine soil suitable for testing. Label each sample carefully, for example, date of collection, whether the previous crop was grown, and use it for both mason jar texture tests and pH testing.
Answer:
* Model Procedure and Sample Log:
1. Collected soil from multiple spots across a local field (sandy patch, organic pit, and near a water channel) in a zig-zag pattern, avoiding shady areas under trees and fertilizer storage spots.
2. Removed stones, leaves, and debris from the collected soil.
3. Sun-dried the soil for 3 hours, crushed hard clumps, and sieved the mixture to obtain fine soil.
4. Labeled the sample container with collection date (12th August), field location, and previous crop grown (wheat). Reserved the prepared sample for mason jar texture testing and pH testing.

Q2. TASK: Testing soil for its clay and sand percentage (mason jar test) — Understanding soil texture and pH is another crucial step in evaluating soil health. Soil texture is determined by the amount of sand (largest particles), silt (medium – sized particles) and clay (smallest particles). Soil texture affects how well the soil holds water, nutrients and how easily roots can grow in it. You can assess soil texture through a mason jar test. Figure 1.7 shows the process for the mason jar test. 1. Fill a transparent jar halfway with soil.
Answer:
Procedure:
1. Filled a transparent glass jar halfway with the sieved soil sample.
2. Added water and a few drops of liquid dish soap, leaving space at the top.
3. Shook the jar thoroughly and placed it undisturbed on a flat surface for 24 – 48 hours.
4. Measured settled layers: sand settled at the bottom first, silt in the middle, and clay on top.
Model Test Result:
Sand = 82%, Silt = 12%, Clay = 6%.
Result: Sand percentage is more than 80 per cent – this will hold very little water, leading to wilting of plants.
Action to be taken:* Added compost (organic matter) or garden soil to increase the water-holding capacity of the soil and add necessary nutrients for plants.

Q3. CHECK YOUR UNDERSTANDING:
1. Which test did you do?
2. What were the results of the test?
3. What steps did you take to improve the quality of the soil?
Answer:
1. Tests Performed: Conducted the Mason Jar Soil Texture Test and the Soil pH Slurry Test.
2. Results of the Tests:
Mason Jar Texture Test: Sand = 83%, Silt = 11%, Clay = 6%. This indicates sandy soil with over 80 per cent sand, which holds very little water.
Soil pH Test: The pH strip reading was 5.5, indicating acidic soil (pH below 6).
3. Steps Taken to Improve Soil Quality:
For Sandy Soil (>80% sand): Mixed compost (organic matter) into the soil to increase its water-holding capacity and supply essential plant nutrients.
For Acidic Soil (pH below 6): Added compost, wood ash, or lime/dolomite to neutralize acidity and raise the pH to the optimal slightly acidic to neutral range (pH 6 – 7) required for nutrient absorption.

Q4. TASK: Floating method — 1. Take 1 L water in bucket. 2. Add 100 g salt to water. 3. Add 250 g of wheat seeds. 4. Wait for 3 – 5 minutes. 5. Damaged, infected or hollow seeds float on water. 6. Discard floating seeds, wash remaining seeds in fresh water and dry in shade.
Answer:
Principle: Adding common salt (NaCl) increases the density of water (making water heavier). Hollow, damaged, or insect-infected seeds are lighter and float to the top, while healthy seeds sink to the bottom. Salt water also removes microbial infections from the seed coat.
Model Execution & Observations:
1. Mixed 100 g of common salt in 1 L of water inside a bucket.
2. Poured in 250 g of wheat seeds and waited for 4 minutes.
3. Observed approximately 22 g of hollow/damaged seeds floating on the water surface.
4. Skimmed off and discarded all floating seeds.
5. Collected the healthy sunken seeds, washed them thoroughly in fresh water to remove excess salt, and dried them in shade prior to sowing.

Section 1.4 Selection of vocation Questions & Solutions

Q1. TASK: Exploring vocations around us — Look around you and answer the following questions: 1. What kind of work related to agricultural practices do you observe around yourself? You can use different sources of information, for example, experts, site visits, libraries, online resources, specific government sites or reports. 2. Briefly describe what the work involves – what are the inputs, what are the key processes and what are the outcomes.
Answer:
1. Work Observed: Rooftop Gardening / Nursery Management.
2. Description of Work:
Inputs: Growing media (soil, vermicompost, coco peat), healthy seeds or saplings, containers/pots, water, hand tools (trowels, watering cans), organic fertilizers, and organic pesticides like Daśhaparṇī arka (an organic pesticide made from ten different plant leaves, cow-dung, and cow-urine).
Key Processes: Soil testing and amendment (checking pH [potential of hydrogen, a measure of acidity or alkalinity] and texture), seed selection using the salt-water floating test, preparing vermicompost (compost produced using earthworms), sowing, regular irrigation, pest management, and harvesting.
* Outcomes: Fresh pesticide-free vegetables and herbs, healthy soil maintenance, production of quality saplings, and greening of urban roof spaces.

Q2. PORTFOLIO: Which vocation have you chosen and why?
Answer:
Chosen Vocation: Rooftop Gardening.
Reason for Choice: Selected Rooftop Gardening because urban land space is limited, and rooftops offer unused space to cultivate fresh vegetables. It allows hands-on practice of essential agricultural processes learned in this chapter, such as soil testing, seed treatment, weather tracking, and organic composting.

Q3. Mapping resources: Do you think it is possible for you to do the work in school? Discuss in a group why/why not. Table 1.2 will help you decide.
Answer:
Model Discussion Summary (evaluated against Table 1.2 criteria):
Yes, it is possible to do Rooftop Gardening at school based on resource mapping:
1. Completion in 3 months: Yes, short-duration leafy vegetables can complete their growth cycle within 3 months.
2. Adequate space: Yes, the flat school roof or open balcony provides adequate sunlight and space for growing containers.
3. Expert identified: Yes, our school science teacher and a local agricultural extension officer agreed to guide us.
4. Resource management: Yes, inputs like pots, organic waste, cow dung, seeds, and water can be managed easily at minimal cost.
5. Real hands-on work:* Yes, students can directly collect soil, build weather tools, test seeds, prepare organic fertilizers, and manage plant growth.

Section 1.6 Assess your learning Questions & Solutions

Q1. A farmer has sandy soil with high acidity. Suggest two amendments and explain how they will improve soil quality.
Answer:
1. Adding Compost (Organic Matter):
Explanation: Sandy soil has a sand percentage greater than 80 per cent, which holds very little water and causes plants to wilt. Adding compost increases the water-holding capacity of sandy soil, adds necessary plant nutrients, and improves soil structure.
2. Adding Wood Ash / Lime or Dolomite:
Explanation: Acidic soil has a pH below 6, which prevents plants from absorbing certain essential nutrients. Adding wood ash, lime, or dolomite neutralizes soil acidity, raising the pH to an optimal slightly acidic to neutral range (pH 6 – 7).

Q2. Non-timber Forest Produce (NTFP) refers to all useful products from forests (except timber), including resin, medicinal plants, fruits, nuts, etc. Lac is an important NTFP that is produced by a tiny insect, Kerria lacca, which secretes a resinous substance as a protective coating on the branches of host trees. Lac production is dependent on insect population. Insect growth in turn depends on suitable host plants and a warm and humid climate, among other factors like growth of plant, etc. If you were part of a team building a meteorological observatory to help monitor conditions for the growth of Kerria lacca, which two instruments would you prioritise and why?
Answer:
1. Dry-Wet Bulb Thermometer:
Reason: Kerria lacca insect growth strictly depends on a warm and humid climate. A dry-wet bulb thermometer measures ambient air temperature (dry bulb) and relative humidity (calculated from the difference between dry bulb and wet bulb readings), enabling farmers to monitor humidity and temperature closely.
2. Rain Gauge:
Reason: A rain gauge measures precipitation depth over a specific period. Since excessive rainfall or unexpected heavy rain can damage insect populations or wash away host tree foliage, tracking rainfall helps farmers take timely protective measures.

Q3. Table 1.3 shows the rainfall in a region and the rainfall requirements of some crops. On the basis of the rainfall data, suggest which among the following crops can be safely planted in the region and when. Justify your choice.
Answer:
Rainfall Data Analysis: The annual rainfall in the region over 10 years ranges from 333 mm (lowest in 2016) to 974 mm (highest in 2019), with most years receiving 480 mm to 693 mm.
Crop Recommendations & Timing:
1. Pulses (Requirement: 400 – 500 mm): Can be safely planted in almost all years (including dry years like 2015, 2018, 2021, 2023, and 2024) during the kharif season (monsoon months, June – July sowing) or rabi season, as its water requirement matches the region’s lower rainfall limits.
2. Jawar, Maize, Soyabean, Cotton, Groundnut (Requirement: 500 – 1000 mm / 500 – 1250 mm): Can be safely planted during normal and good rainfall years (such as 2017, 2019, 2020, 2022, and 2024) during the kharif season when monsoon rainfall is maximum.
3. Wheat (Requirement: 750 – 1000 mm): Can be grown during good rainfall years in the rabi season (winter crops, October – December sowing) using stored soil moisture or supplemental irrigation.
* Crops to Avoid: Rice (1500 – 3000 mm) and Jute (1250 – 2000 mm) should not be planted relying on rainfall alone, because the region’s maximum annual rainfall (974 mm) falls far short of their minimum requirements.

Q4. Create a farm-to-plate journey map for any farming produce. Indicate the value chain as the produce travels from where it was grown to the table in the form of food.
Answer:
Farm-to-Plate Value Chain Journey Map (Wheat Produce):
1. Farming / Production (Base Cost = ₹100): Cultivation, harvesting, and initial farm-gate sale of wheat grains by the farmer.
2. Post-Harvest Handling (Adds 15 – 20% value): Cleaning, sorting, grading, and storage in warehouses.
3. Processing (Adds 30 – 50% value): Grinding wheat grains into flour (atta) in processing mills.
4. Marketing & Distribution (Adds 15 – 20% value): Transporting, packaging, branding, and wholesale distribution to mandis (agricultural markets) and supermarkets.
5. Consumption / Table (Adds 10 – 15% value): Final retail purchase by consumers and preparation into food on the dining table.
(Note: If hybrid seeds are used, initial seed research adds an additional 20 – 400% value).

Q5. Of the tasks that you did, which did you enjoy the most? Which did you enjoy the least? Give examples of what went well and what did not go well. What would you do differently next time?
Answer:
Task Enjoyed the Most: Building the DIY rain gauge and wind vane, and observing soil layers separate during the mason jar texture test.
Task Enjoyed the Least: Waiting 30 – 40 days for the fermentation of Daśhaparṇī arka pesticide due to its strong smell during daily stirring.
What Went Well: The salt-water seed floating test worked efficiently; hollow, damaged seeds floated to the top within 5 minutes and were easily discarded.
What Did Not Go Well: Our first DIY rain gauge blew over during strong winds because the base was too light.
* What to Do Differently Next Time: Anchor the rain gauge firmly with heavy stones or mount it securely at a height, and collect soil samples from more spots across the field in a proper grid pattern.

Q6. Give examples of how you can apply your learning in a real-life situation.
Answer:
1. Soil & Seed Quality Management: Test garden soil pH using pH paper and amend acidic soil with wood ash or compost before planting vegetables at home. Perform the salt-water floating test on crop seeds to ensure only healthy seeds are sown.
2. Weather Monitoring for Farming: Use simple DIY weather tools (rain gauge, dry-wet bulb thermometer) or digital apps like GKMS and Bharat-VISTAAR to track rainfall and humidity, helping local farmers schedule irrigation and protect crops from frost or wind damage.
3. Preparing Organic Inputs: Convert agro waste and cow dung into nutrient-rich vermicompost, and prepare organic pesticide (Daśhaparṇī arka) from local plant leaves (neem, papaya) to manage crop pests without using chemical sprays.
4. Smart Purchasing: Apply knowledge of the agricultural value chain to compare produce costs between local mandis and supermarkets to make informed purchasing choices.
