Answer 1

Hint: Agriculture involves preparation of the field, sowing, irrigation, use of pesticides and then cutting of the crops. Seed drill is the device used in agriculture. The use of a seed drill prevents the seeds from being eaten by the birds.

Complete answer:
We are already aware that the seed drill is used to sow the seeds. Let us see what are the other functions of the seed drill.

Before the invention of seed drill, the seeds were sowed by broadcasting. By this method, the problem of the overlapping of the seeds and poor distribution was faced. After the invention of seed drill the crop yield was improved to several folds. Furrows are made with a plough by making linear cuts.

The seed drill is used to sow seed, position them in the soil and bury them at specific depth. This allows the seeds to be placed evenly. Even placing of the seeds ensures proper sunlight, nutrients and water to the growing plants. The seed drill ensures the seeds are evenly placed in rows. The burying of the seeds prevents the seeds from being dried up or eaten by birds or animals. This method saves time as well as labor.

Hence the correct answer is option (d).

Note: The use of seed drill prevents the growth of the weed. The weeding helps in higher yield. Before the use of seed drill, the soil must be ploughed so as it breaks the clumps and also provides aeration. The seed drill is moved across the field by using bullocks or tractors.
