Boojho wants to know where we use the tools like khurpi, sickle, shovel, plough, etc.?<br>Ans. We use tools like khurpi, sickle, shovel, plough, etc., in agricultural activities.<\/p>\n\n\n\n<p>Q. 2. Boojho wants to know, since we all need food, how can we provide food to a large number of people in our country?<br>Ans. Food will have to be produced on a large scale. In order to provide food for a large population, regular production, proper management and distribution of food are necessary.<\/p>\n\n\n\n<p>Q. 3. Boojho wants to know why paddy cannot be grown in the winter season.<br>Ans. Paddy requires a lot of water. So, it is grown only in the rainy season.<\/p>\n\n\n\n<p><mark style=\"background-color:#00ff2f\" class=\"has-inline-color\">Page-4<\/mark><\/p>\n\n\n\n<p>Q. 4. One day Paheli saw her mother put some gram seeds in a vessel and pour some water on them. After a few minutes, some seeds started to float on the top. She wondered why some seeds floated on water?<br>Ans. Damaged seeds become hollow and are thus lighter. Therefore, they floation water.<\/p>\n\n\n\n<p>Q. 5. Boojho saw one nursery near his school. He found that little plants were kept in small bags. He wants to<br>know, why?<br>Ans. Seeds of a few plants such as paddy are first grown in nursery. When small plantlets are formed, they are transplanted in the field manually. Some forest plants and flowering plants are also grown in the nursery.<\/p>\n\n\n\n<p>Q. 6. Boojho went to a farm and saw a healthy crop growing there. Whereas in the neighbouring farm the plants were weak. He asked Paheli why do some plants grow better than others?<br>Ans. This is because of insufficient manuring and care.<\/p>\n\n\n\n<p><mark style=\"background-color:#00ff2f\" class=\"has-inline-color\">Page-10<\/mark><\/p>\n\n\n\n<p>Q. 7. Boojho told the farmer that there were other plants growing along with wheat. He wanted to know if they had been purposely grown.<br>Ans. No, in a crop field many other undesirable plants may grow naturally along with the crop, these are called weeds.<\/p>\n\n\n\n<p>Q. 8. Boojho wants to know whether weedicides have any effect on the person handling the weedicide sprayer.<br>Ans. Yes, sprayer of weedicide may affect the health of farmers.<\/p>\n\n\n\n<p>Q. 9. One day Paheli saw her mother putting some dried neem leaves in an iron drum containing wheat. She wondered, why?<br>Ans. This prevents the attack by insects, pests, bacteria and fungi.<\/p>\n\n\n\n<p><\/p>\n\n\n\n<h4 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Exercise_Questions\"><\/span><mark style=\"background-color:#fbff66\" class=\"has-inline-color\">Exercise Questions<\/mark><span class=\"ez-toc-section-end\"><\/span><\/h4>\n\n\n\n<p>Q. 1. Select the correct word from the following list and fill in the blanks:<br>        float, water, crop, nutrients, preparation.<br>(i) The same kind of plants grown and cultivated on a large scale at a place is called __________.<br>(ii) The first step before growing crops is __________of the soil.<br>(iii) Damaged seeds would __________on top of water.<br>(iv) For growing a crop, sufficient sunlight, __________and __________from the soil are essential.<\/p>\n\n\n\n<p>Ans. (i) crop, (ii) preparation, (iii) float, (iv) water, nutrients<\/p>\n\n\n\n<p>Q. 2.

Give two examples of each:<br>(i) Kharif Crop (ii) Rabi crop<\/p>\n\n\n\n<p>Ans. (i) Kharif Crop: Soyabean and Groundnut.<br>(ii) Rabi Crop: Pea and mustard.<\/p>\n\n\n\n<p>Q. 4. Write a paragraph in your own words on each of the following:<br>(i) Preparation of soil (ii) Sowing (iii) Weeding (iv) Threshing.<\/p>\n\n\n\n<p>Ans. <strong>(i) Preparation of soil: <\/strong>Soil is prepared before sowing the seeds. The soil is loosened to increase the absorption of water and manure. Loosening of soil particles adds humus and nutrients in the soil that increases crop yields. Tilling or loosening the soil is done by plough which is pulled by a pair of bulls. Tractor driven cultivators are also used to loosen the soil.<\/p>\n\n\n\n<p><strong>(ii) Sowing:<\/strong> After preparation of soil, it is ready for sowing of seeds. Healthy and clean seeds should be selected. Sowing is done by seed drill or funnel shaped tools. Seed drill is a modern instrument which can sow seeds at proper depth and distance.<\/p>\n\n\n\n<p><strong>(iii) Weeding:<\/strong> The unwanted plants that grow along with the crops are called weeds. They hinder the growth of plant, by absorbing nutrients from the soil. Thus, it is necessary to remove them, otherwise, they make the soil nutrient deficient. The process of removing weeds is called weeding. It can be done manually or by mechanical tools. Some chemicals like 2,4-D can also be used.<\/p>\n\n\n\n<p><strong>(iv) Threshing:<\/strong> The separation of grains from the chaff is called threshing. When the crop matures, it is harvested and cut along with the stalks. Grains are then separated from the chaff using a winnowing machine.<\/p>\n\n\n\n<p>Q. 5. Explain how fertilisers are different from manures.<\/p>\n\n\n\n<p>Ans. (i) Manures are organic substances, while fertilisers are chemical substances.<br>(ii) Manures are prepared in fields, while fertilisers are prepared in factories.<br>(iii) Manures contain all the nutrients, while fertilisers are rich in certain nutrients.<br>(iv) Manures provide humus, while fertilisers do not. <\/p>\n\n\n\n<p>Q. 6. What is irrigation? Describe two methods of irrigation which conserve water.<\/p>\n\n\n\n<p>Ans. The supply of water to crops at different intervals is called irrigation. Latest irrigation methods help us to use water economically. The main methods used are as follows:<\/p>\n\n\n\n<p><strong>(i) Sprinkler system:<\/strong> This system is more useful on the uneven lands where water is available in smaller quantity. The perpendicular pipes, having rotating nozzles on the top, are joined to the main pipe lines at regular intervals. When the water is allowed to flow through the main pipe with the help of a pump, it escapes from the rotating nozzles. It is sprinkled on the crop as if it is raining. A sprinkler is very useful for sandy soil.<\/p>\n\n\n\n<p><strong>(ii) Drip system:<\/strong> In this system, the waterfalls drop by drop just at the position of the roots. So, it is called drip system. It is the best technique of watering fruit plants, gardens and trees. This system consists of a main pipe to which lateral pipes are joined. The specially prepared nozzles are attached to these lateral pipes. The nozzles are grounded just near the roots of the plants. Water is not wasted at all. So, it is a boon in regions where the availability of water is poor.<\/p>\n\n\n\n<p>Q. 7. If wheat is sown in the Kharif season, what would happen? Discuss.<\/p>\n\n\n\n<p>Ans. Wheat&#8217;s seeds need low temperature and less humidity to grow. If they are sown in Kharif season (i.e., rainy season), the seeds would get destroyed due to excess of water and would not grow.<\/p>\n\n\n\n<p>Q. 8. Explain how soil gets affected by the continuous plantation of crops in a field.<\/p>\n\n\n\n<p>Ans. Soil is the source for plants from which they derive their mineral nutrients, essential for their growth. If crops are grown continuously in the same field, for a long period of time, the soil becomes deficient in nutrients. Thus, the field becomes infertile.<\/p>\n\n\n\n<p>Q.9. What are weeds? How can we control them?<\/p>\n\n\n\n<p>Ans. Weeds are the undesirable (unwanted) plants that may grow naturally along with the crops. They are hazardous to the crops as they compete with the crop for food, nutrients, water and sunlight. Hence, they must be controlled. The process of controlling or removing weeds from the field is known as weeding. There are several methods to remove weeds such as tilling in which weeds are uprooted. They are also controlled by chemicals known as weedicides which kill the weeds, e.g., 2,4-D.<\/p>\n\n\n\n<p>Q. 10.

Agriculture:<\/strong> The word &#8216;agriculture&#8217; is derived from the Latin word <em>&#8216;agar&#8217;<\/em> meaning &#8216;field&#8217; and <em>&#8216;culture&#8217;<\/em> meaning &#8216;to grow or cultivate&#8217;. The branch of biology which deals with cultivation of plants and rearing of animals is called agriculture. The activity or business of growing crops and raising livestock is called farming.\n  <\/p>\n  <p>\n    <strong>2. Animal Husbandry:<\/strong> Breeding and feeding of domestic animals to obtain milk, meat, fibre, and eggs is called animal husbandry.\n  <\/p>\n  <p>\n    <strong>3. Crop:<\/strong> When plants of the same kind are grown and cultivated at one place on a large scale, it is called a crop.\n  <\/p>\n  <p>\n    <strong>4. Crops Classification Based on Growing Seasons:<\/strong>\n    <ul>\n      <li>\n        <strong>(a) Kharif Crops:<\/strong> Grown during the monsoon (rainy season) (June-September) and harvested at the end of the monsoon season (Oct.-Nov.). Kharif crops are also called summer crops. Examples: maize, millet (bajra), paddy (rice), groundnut, pulses, soybean, and cotton.\n      <\/li>\n      <li>\n        <strong>(b) Rabi Crops:<\/strong> Grown during the winter season (October-March) and harvested at the end of the winter season (April-May). Rabi crops are also called winter crops. Examples: wheat, gram, pea, and mustard.\n      <\/li>\n      <li>\n        <strong>(c) Zaid Crops:<\/strong> Grown during March-June in some parts of India. Examples: muskmelon, watermelon, bitter gourd, pumpkin, and ridged gourd.\n      <\/li>\n    <\/ul>\n  <\/p>\n  <p>\n    <strong>5. Agricultural Practices:<\/strong> Systematic steps and tools used for crop production in the field are called agricultural practices. The tools involved in cultivation are referred to as <em>agricultural implements<\/em>.\n  <\/p>\n <p>\n    <strong>6. Sequential Agricultural Practices:<\/strong> Farmers perform agricultural practices in a sequence:\n    <ul>\n      <li>(a) Preparation of soil<\/li>\n      <li>(b) Selection and sowing of seeds<\/li>\n      <li>(c) Adding manure and fertilisers<\/li>\n      <li>(d) Irrigation<\/li>\n      <li>(e) Protection from weeds<\/li>\n      <li>(f) Harvesting and threshing<\/li>\n      <li>(g) Storage<\/li>\n    <\/ul>\n  <\/p>\n  <p>\n    <strong>7. Preparation of Soil:<\/strong> Before sowing the crop seeds, the soil of fields is loosened and overturned to remove crumbs (big soil pieces). This is done by <em>ploughing or tilling<\/em> and <em>levelling<\/em>. It causes ventilation of soil, allows the roots to breathe easily, helps them grow deep into the soil, and supports the growth of small organisms like earthworms and certain microbes. The top layer of soil supports plant growth. Turning and loosening of soil also brings nutrient-rich soil to the top so that plants can use these nutrients. Implements used for ploughing \nare:\n  <\/p>\n    <ul>\n      <li><strong>(i) Plough:<\/strong> A large farming implement with blades used to turn over and cut furrows in soil. Ploughs can be made of wood, a combination of wood and iron, or only iron.<\/li>\n      <li><strong>(ii) Ploughshare:<\/strong> The main cutting blade of a plough.<\/li>\n      <li><strong>(iii) Hoe:<\/strong> A tool used for removing weeds and loosening the soil.<\/li>\n      <li><strong>(iv) Cultivator:<\/strong> Ploughing done using a tractor-driven cultivator saves time and labour.<\/li>\n    <\/ul>\n  <\/p>\n  <p>\n    <strong>8. Selection and Sowing of Seeds:<\/strong> Good quality, disease-resistant seeds are selected by putting them in a bucket of water. Defective seeds float and are rejected, while healthy seeds sink and are chosen. The selected seeds are treated with fungicides to prevent seed-borne diseases.\n  <\/p>\n  <p>\n    Seeds are sown in three ways:\n    <ul>\n      <li>Manually<\/li>\n      <li>Hand-broadcasting (spreading)<\/li>\n      <li>Using a <strong>seed drill:<\/strong> A long iron pipe with a funnel at the top tied at the back of the plough. The plough creates furrows, and seeds pass through the iron pipe into the soil.<\/li>\n    <\/ul>\n  <\/p>\n  <p>\n    <strong>9. Advantages of Sowing Seeds with a Seed Drill:<\/strong>\n    <ul>\n      <li>(a) Seeds are sown uniformly at proper depth and distance.<\/li>\n      <li>(b) Seeds get covered with soil and are protected from birds.<\/li>\n      <li>(c) Faster sowing saves time and labour.<\/li>\n      <li>(d) Prevents wastage of seeds due to unequal distribution.<\/li>\n    <\/ul>\n  <\/p>\n<p>\n  <strong>10. Transplantation:<\/strong> Some seeds are grown in a nursery. When they grow into seedlings, they are transplanted to the main field manually. This is called transplantation. Rice, chillies, and tomatoes are often grown by transplantation. It has the following benefits:\n  <ul>\n    <li>(a) Only healthy seedlings are transferred to the main field.<\/li>\n    <li>(b) Seedlings are planted with sufficient spacing between them to increase their yield and production.<\/li>\n  <\/ul>\n<\/p>\n\n<p>\n  <strong>11. Adding Manures and Fertilisers:<\/strong> Crop plants also obtain their mineral nutrients from the soil. Nutrients added to the soil for the healthy growth of plants and to make up the deficiency of mineral nutrients are manure and fertilisers. The mixing of these substances with the soil is called manuring.\n<\/p>\n\n<p>\n  <strong>12. Manure:<\/strong> Manure is an organic fertiliser which is prepared from animal dung, urine, plant, and other wastes. Commonly used manures are farmyard manure (FYM), green manure, compost manure, and vermicompost manure, etc.\n<\/p>\n<p>\n  <strong>13. Fertilisers:<\/strong> Fertilisers are chemical substances or compounds that are added to the soil in order to provide specific nutrients to the soil. That&#8217;s why chemical fertilisers are nutrient-specific. For example, urea, super phosphate, and NPK (Nitrogen, Phosphorus, and Potassium).\n<\/p>\n\n<p>\n  <strong>14. Advantages and Disadvantages of Using Chemical Fertilisers:<\/strong> Following are the advantages and disadvantages of using chemical fertilisers:\n<\/p>\n\n<table border=\"1\">\n  <thead>\n    <tr>\n      <th colspan=\"2\"><strong>Advantages<\/strong><\/th>\n      <th colspan=\"2\"><strong>Disadvantages<\/strong><\/th>\n    <\/tr>\n  <\/thead>\n  <tbody>\n    <tr>\n      <td>1.<\/td>\n      <td>Fertilisers provide specific nutrients needed by the crop.<\/td>\n      <td>1.<\/td>\n      <td>It causes water and soil pollution.<\/td>\n    <\/tr>\n    <tr>\n      <td>2.<\/td>\n      <td>Fertilisers are a continuous source of soil nutrients.<\/td>\n      <td>2.<\/td>\n      <td>They make soil less fertile, more acidic, or more basic.<\/td>\n    <\/tr>\n    <tr>\n      <td>3.<\/td>\n      <td>Fertilisers are easily absorbed by the plants and utilised.<\/td>\n      <td>3.<\/td>\n      <td>Excessive use of fertilisers can damage the crop plants.<\/td>\n    <\/tr>\n    <tr>\n      <td>4.<\/td>\n      <td>They are easy to handle, store, and transport in comparison to manure.<\/td>\n      <td>4.<\/td>\n      <td>Fertilisers are costly.<\/td>\n    <\/tr>\n  <\/tbody>\n<\/table>\n\n<p>\n  <strong>15. Crop Rotation and Nitrogen Fixation:<\/strong> \n  <br>\n  <strong>Crop rotation:<\/strong> Cultivation of crops in successive order in the same field, to prevent nutrient deficiency in soil and get better yield, is called crop rotation.\n  <br>\n  <strong>Nitrogen fixation:<\/strong> The process of conversion of free atmospheric nitrogen into useful nitrogenous compounds is called nitrogen fixation. Rhizobium bacteria are present in the roots of the nodules of leguminous plants, which fix atmospheric nitrogen.\n<\/p>\n<p>\n  <strong>16. Some of the Differences Between Manure and Fertilisers:<\/strong>\n<\/p>\n\n<table border=\"1\">\n  <thead>\n    <tr>\n      <th>S.

Advantages of Manure Over Fertilisers:<\/strong> The organic manure is considered better than fertilisers because:\n  <ul>\n    <li>(a) It enhances the water holding capacity of the soil.<\/li>\n    <li>(b) It makes the soil more porous, which helps the exchange of gases.<\/li>\n    <li>(c) It increases the number of friendly microbes.<\/li>\n    <li>(d) It improves the texture of the soil.<\/li>\n  <\/ul>\n<\/p>\n\n<p>\n  <strong>18. Irrigation:<\/strong> The process of watering crops at regular intervals is called irrigation. The time and frequency of irrigation vary from crop to crop, soil to soil, and season to season.\n<\/p>\n\n<p>\n  <strong>Importance of Irrigation:<\/strong> Irrigation is important for the following:\n  <ul>\n    <li>(a) It is helpful for the processes of photosynthesis and transpiration.<\/li>\n    <li>(b) Seeds germinate in moist soil only.<\/li>\n    <li>(c) It is important for the growth and development of the plant.<\/li>\n    <li>(d) It is essential for the elongation of roots.<\/li>\n  <\/ul>\n<\/p>\n\n<p>\n  <strong>19. Methods of Irrigation:<\/strong> It depends upon the availability of water, type of crop, and the region to be irrigated. These methods are divided into two categories, namely traditional and modern methods of irrigation.\n<\/p>\n\n<p>\n  <strong>(a) Traditional methods:<\/strong> Moat (pulley-system), chain pump, dhekli, rahat (lever system), etc.\n<\/p>\n<p>\n  <strong>(b) Modern methods:<\/strong> Sprinkler system, drip irrigation system, basin irrigation, furrow irrigation, etc.\n<\/p>\n<p>\n  <strong>20. Modern Methods:<\/strong> Modern methods are considered to be more economical than the traditional system. For this, there are two methods that are widely used:\n<\/p>\n\n<p>\n  <strong>(a) Sprinkler System:<\/strong> In this system, perpendicular pipes are laid in the field. The sprinklers are fixed in these pipelines, which have a rotating nozzle at the top. The sprinklers rotate in all directions to provide an even supply of water in the field. It is recommended for sandy soil.\n<\/p>\n\n<p>\n  <strong>(b) Drip Irrigation:<\/strong> This system provides water to the plants drop by drop just at the base of the root. This is also called trickle irrigation. It saves water as well as allows the fertilisers to drip slowly near the roots.\n<\/p>\n\n<p>\n  <strong>21. Benefits or Advantages of Modern Methods Over Traditional Methods of Irrigation:<\/strong>\n  <ul>\n    <li>(a) Modern methods of irrigation avoid wastage of water.<\/li>\n    <li>(b) It helps to conserve water, which is lost by evaporation.<\/li>\n    <li>(c) It helps to distribute equal parts of water in a field.<\/li>\n  <\/ul>\n<\/p>\n\n<p>\n  <strong>22. Waterlogging and Its Effects:<\/strong> When too much water stands in the field, it accumulates around the roots. This is called waterlogging. It has the following disadvantages:\n<\/p>\n<ul>\n    <li>(a) Waterlogging reduces air in the spaces between soil particles, hence, it reduces the oxygen supply to roots.<\/li>\n    <li>(b) Waterlogging reduces the fertility of the soil.<\/li>\n  <\/ul>\n<\/p>\n\n<p>\n  <strong>23. Protection from Weeds:<\/strong> The naturally occurring unwanted plants in the fields that compete for nutrients, water, space, and sunlight with the standing plants\/crops are called weeds. Therefore, their removal is necessary. The removal of weeds is called weeding.\n<\/p>\n\n<p>\n  <strong>24. Methods of Weeding:<\/strong> Following methods are adopted for removing the weeds from a crop field:\n  <ul>\n    <li><strong>(a) Manual Method:<\/strong> It is done by just pulling out the weeds from a crop field.<\/li>\n    <li><strong>(b) Mechanical Method:<\/strong> Weeds are weeded out with the help of an implement called harrow or rake. It can also be removed by using trowel (khurpi) or hoe.<\/li>\n    <li><strong>(c) Chemical Method:<\/strong> Chemical substances used for the removal or checking the growth of weeds are called weedicides. For example, 2, 4-D, MCPA, butachlor, metachlor, etc., are used as weedicides.<\/li>\n    <li><strong>(d) Biological Method:<\/strong> In this method, some natural enemies of the weeds are put in the fields which will feed on weeds and destroy them. For example, cochineal insects are used to eliminate the opuntia plant from crops.<\/li>\n  <\/ul>\n<\/p>\n\n<p>\n  <strong>25. Harvesting and Threshing:<\/strong> Cutting and gathering of the crops is done once they get matured, and this is known as harvesting. Harvesting is either done manually by a sickle or by a machine called a harvester. The harvested crop is further dried and then animals such as bullocks, buffaloes, and camels are made to walk over it. The grains are separated from the chaff with the help of wind called <strong>winnowing<\/strong>.\n<\/p>\n\n<p>\n  The process of separation of the grains from the harvested crop is known as <strong>threshing<\/strong>. It is also done manually by hitting against a hard surface. Big farmers use huge machines known as combines which do both harvesting and threshing.\n<\/p>\n<p>\n  <strong>26. Special Festivals Associated with the Harvest Seasons:<\/strong> \n  Pongal, Baisakhi, Holi, Diwali, Nabanya, and Bihu are celebrated in various states of India after crop harvesting.\n<\/p>\n\n<p>\n  <strong>27. Storage:<\/strong> Grains obtained by threshing are dried in the open. The dried grains are stored in gunny bags, and placed in properly ventilated and cemented godowns. Farmers keep dried grains in jute bags or metallic bins or mud bins. Large scale storage of grains is done in silos and granaries. For storing large quantities of grains in big godowns, specific chemical treatments are done to protect them from pests and microorganisms.\n<\/p>\n\n<\/details>\n\n\n\n<p><\/p>\n\n\n\n<style>\n  details summary {\n    font-size: 20px; \/* Adjust the size as needed *\/\n    font-weight: bold; \/* Make it bold for better visibility (optional) *\/\n    cursor: pointer; \/* Changes the cursor to a pointer *\/\n    margin-bottom: 5px; \/* Optional spacing *\/\n  }\n<\/style>\n<details>\n  <summary>Keywords (Click to expand)<\/summary>\n  <p>\n  <strong>Agriculture:<\/strong> Applied branch of biology which involves the practice of cultivating crops as well as rearing animals.\n<\/p>\n\n<p>\n  <strong>Cultivation of Soil:<\/strong> Digging soil to prepare it for planting.\n<\/p>\n\n<p>\n  <strong>Sowing:<\/strong> Process of scattering or putting seeds into the soil to grow a new crop plant.\n<\/p>\n\n<p>\n  <strong>Crop rotation:<\/strong> Practice of growing a series of different types of crops in the same field.\n<\/p>\n\n<p>\n  <strong>Silos:<\/strong> A tall tower on a farm used to store grain.\n<\/p>\n\n<p>\n  <strong>Granaries:<\/strong> Storehouses for threshed grain.\n<\/p>\n\n<p>\n  <strong>Animal rearing:<\/strong> Process of raising, feeding and taking care of domestic animals.\n<\/p>\n<\/details>\n\n\n\n<p><\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Frequently_Asked_Questions_FAQs_on_Crop_Production_and_Management_Class_8_NCERT_Solutions\"><\/span>Frequently Asked Questions (FAQs) on Crop Production and Management Class 8 NCERT Solutions<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n<div id=\"rank-math-faq\" class=\"rank-math-block\">\n<div class=\"rank-math-list \">\n<div id=\"faq-question-1734374533621\" class=\"rank-math-list-item\">\n<h4 class=\"rank-math-question \"><span class=\"ez-toc-section\" id=\"Q1_What_are_NCERT_Solutions\"><\/span>Q1: What are NCERT Solutions?<span class=\"ez-toc-section-end\"><\/span><\/h4>\n<div class=\"rank-math-answer \">\n\n<p>A1: NCERT Solutions are detailed, step-by-step answers to the questions provided in the NCERT textbooks.
