NCERT Class 8 Science Chapter 1 Crop Production and Management- Important Topics
To provide food to people of our country, we need a good system for regular production of food on a large scale, its proper management and distribution throughout the country.
- Agricultural Practices
This portion of the NCERT Solutions CBSE Class 8 Science chapter 1 tells you that climatic conditions of India vary from one region to another at a given time. Accordingly, a large variety of crops are grown here. The broad cropping types of India are Kharif (sown in rainy season) and Rabi (sown in winter season).
- Basic Practices of Crop Production
This section tells you the main activities performed in agriculture – such as preparation of soil, sowing, adding manure and fertilisers, irrigation, protecting from weeds, harvest and storage.
- Preparation of Soil
This part of the chapter conveys the necessity of turning and loosening soil also known as tilling or ploughing before sowing seeds as loose soil allows roots to penetrate deeper in soil, breath and absorb nutrition properly from the soil. Loose soil also helps the growth of earthworms and good microbes which enhance the nutritive value of soil.
- Agricultural implements
This subtopic introduces you to the methods of ploughing which include use of the plough, hoe and tractor drove cultivator. These are some instruments used commonly.
This portion of the chapter tells you that the selection of good and healthy seeds leads you to high yielding crops. It also lets you know about the traditional funnel-shaped tool for sowing. It talks about the seed drill tool, which is used nowadays and is better equipped to sow seeds uniformly at proper distances and depths.
- Adding manure and fertilisers
This part of the chapter tells you the importance of manuring the soil. As the continuous growing of crops leads to depletion of nutrition from soil, farmers need to replenish the soil with nutrients. It also tells you about the methods of replenishing soil such as adding manure that is produced from decomposed organic matter, adding fertilisers made of chemical substances rich in specific nutrients and crop rotation. It also discusses the advantages of manure over fertilisers
This part of the chapter tells you that irrigation is the supply of water to crops at different intervals, and water bodies around us are used as a source for irrigation.
- Methods of irrigation
This section tells you about the usage of pulley system, chain pump, Dhekli and Rahat to pull water from water sources like canals, wells, lakes etc. utilising humans or animals. Electricity or diesel operated pumps are also used for pulling water.
- Methods of irrigation
This part tells you about the use of sprinkler and drip system of water supply which is better and more economical.
- Protection from weeds
This part of the chapter introduces you to weeds which are undesirable plants growing along with crop and the process of removal of weeds known as weeding. Weeding can be done manually, or chemicals can be used, which kills the weeds specifically.
This part of the chapter tells you about the important task of harvesting, which is cutting the mature crop either manually by sickle or by using a machine called harvester. Then threshing or winnowing is performed to separate grains from the chaff.
This topic of the Class 8 Science Crop Production and Management chapter deals with the important task of moisture, insect and microbe-free storage of grains in jute bags, metallic bins at a smaller level and in silos and granaries at a bigger level.
- Food from animals
This part of the chapter tells you that food is also obtained from animals for which they are reared, and this practice is known as Animal husbandry.
