FAQs on L17 : Harvesting - Crop Production & Management, Science, Class 8 Video Lecture

1. What is crop production and management?
Ans. Crop production and management refers to the process of growing crops and managing them effectively to obtain a good yield. It involves various activities such as selection of suitable crops, preparation of the soil, sowing of seeds, watering, weeding, application of fertilizers and pesticides, and harvesting.
2. How can I select suitable crops for my farm?
Ans. To select suitable crops for your farm, you need to consider factors such as climate, soil type, availability of water, and market demand. Different crops have specific requirements for temperature, rainfall, and soil fertility. Conducting a soil test and understanding the climate conditions of your area will help you determine which crops are suitable for cultivation.
3. What are the steps involved in crop production?
Ans. The steps involved in crop production are as follows: 1. Selection of suitable crops based on climate and soil conditions. 2. Preparation of the soil by plowing, leveling, and adding organic manure. 3. Sowing of seeds or transplanting seedlings. 4. Watering the plants regularly. 5. Removing weeds to prevent competition for nutrients and sunlight. 6. Applying fertilizers to enhance soil fertility. 7. Protecting the crops from pests and diseases through the application of pesticides. 8. Harvesting the mature crops at the right time.
4. How often should I water my crops?
Ans. The frequency of watering crops depends on various factors such as the type of crop, soil moisture level, and weather conditions. Generally, it is recommended to water crops when the top layer of soil feels dry to touch. However, it is important to avoid overwatering as it can lead to waterlogging and root rot. Regularly monitoring the moisture level of the soil is crucial in determining the watering schedule for your crops.
5. What are the benefits of using organic manure in crop production?
Ans. Organic manure, such as compost and farmyard manure, has several benefits in crop production. It improves soil fertility by adding essential nutrients and micronutrients to the soil. It enhances the soil structure, making it more suitable for root growth and water retention. Organic manure also promotes the growth of beneficial microorganisms in the soil, which aids in nutrient cycling and pest control. Additionally, it reduces the risk of chemical residue in crops, making them healthier and safer for consumption.
