Q: Why is loosening of soil important?
A: Loosening soil allows roots to penetrate deep, helps roots breathe easily, promotes growth of earthworms and microbes, and brings nutrient-rich soil to the top.
Q: What is the difference between manure and fertilizers?
A: Manure is an organic substance obtained from decomposition of plant or animal waste, while fertilizers are chemical substances produced in factories that are rich in specific nutrients.
Q: What are the advantages of using manure?
A: Manure enhances water holding capacity of soil, makes soil porous, increases friendly microbes, and improves soil texture.
Q: What is irrigation?
A: Irrigation is the supply of water to crops at regular intervals to maintain soil moisture for healthy crop growth.
Q: What are weeds?
A: Weeds are undesirable plants that grow naturally along with crop plants and compete for water, nutrients, space, and light.
Q: How can weeds be controlled?
A: Weeds can be controlled by tilling before sowing, manual removal using a khurpi, or by using chemical weedicides like 2,4-D.
Q: What is harvesting?
A: Harvesting is cutting of mature crops, usually done manually with a sickle or by using a machine called a harvester.
Q: Why is proper grain storage important?
A: Proper storage protects grains from moisture, insects, rats, and microorganisms. Grains are dried in the sun before storage to prevent spoilage.
Q: What is crop rotation?
A: Crop rotation is growing different crops alternately to replenish soil nutrients. For example, growing legumes in one season and wheat in the next.
Q: What are traditional methods of irrigation?
A: Traditional methods include moat (pulley system), chain pump, dhekli, and rahat (lever system).
Q: What are modern methods of irrigation?
A: Modern methods include sprinkler system and drip system, which help use water more economically.
Q: What is threshing?
A: Threshing is the process of separating grain seeds from the chaff, often done using a combine machine.
- Q: Why should farmers add manure or fertilizers to soil?
A: Continuous cultivation makes soil poor in nutrients, so manure and fertilizers are added to replenish nutrients and ensure healthy plant growth.
Q: What is vermicomposting?
A: Vermicomposting is a method of creating organic manure using earthworms to decompose plant and animal waste.
Q: What is animal husbandry?
A: Animal husbandry is the large-scale rearing of animals, providing them with proper food, shelter, and care to obtain food products.
Q: Why is seed selection important in crop production?
A: Seed selection is crucial to choose high-yield, good quality, clean, and healthy seeds that will produce better crops.
