NCERT Solutions For Class 8 Science Chapter 1 FAQs
How do farmers separate healthy and damaged seeds?
Farmers can put some seeds in a container full of water and stir them thoroughly. After some time, the damaged seeds are found floating on water because they are hollow from inside and thus lighter. These damaged seeds are then separated.
How do manures differ from fertilizers from a production point of view?
Fertilizers are produced in factories, whereas manures are natural substances obtained by decomposing animal wastes and residues.
What are the seasonal times for Kharif and Rabi crop production?
Kharif crops are grown in rainy seasons, and Rabi crops are cultivated in winter seasons.
How is drip irrigation used in areas with poor water availability?
In drip irrigation, water is supplied drop-by-drop in a particular position, especially on the roots of plants. It saves a lot of water without any waste, so it is useful in areas with poor water availability.
What is the correct time to apply weedicides?
The best time for spraying weedicides to destroy weeds in the field is before flowering and seed formation in crops.
