Explanation:

1) The Kharif crops are sown at the beginning of the first monsoon season in India. Examples are rice, maize, bajra, ragi, etc. So the statement is true.

2) Rabi crops are winter crops, growing in colder climates. Jute is not a Rabi crop, which is an example of a Kharif crop. So the statement is false

3) The grains yielded after the harvest are stored in granaries for later use or marketing. It's a kind of agricultural practice just like sowing, manuring, and weeding.  Hence the statement is false.

4) Levelling is the process of breaking down the larger lumps of the soil to create a level surface for agriculture. Hence the statement is true.

5) Levelling reduces soil erosion and ensures uniform irrigation for the entire area. So the statement is true.

6) The method of loosening the soil is called plowing. Weeding is the process of removing unwanted plants that grow along with the crop. Hence the statement is false.

7) Putting some dried neem leaves in the drum containing grains is another agricultural practice. Thereby it can prevent the attack of pests. Hence it is a true statement.

8) The irrigation process improves the fertility of the soil. Hence the statement is false

9) Kharif crops are sown after the first monsoon and the crops grow between June to September. So the statement is true.

10) Peas are an example of a Rabi crop. Hence the statement is false

11) The first practice done by the farmers is plowing the soil and making it useful for agriculture. Hence it is a true statement.

12) Combines are used for harvesting and winnowing. Hence the statement is false.

13) Loosening of soil is done by a plow which allows the roots of the saplings to breathe easily. Hence it is a true statement.

14) Pesticides are chemical compounds used to combat pests such as insects, rodents(rats), fungi, and weeds. Hence it is a true statement.

15) The drip irrigation system can be used in regions where water is scarcer. And it is an economical method of irrigation. Hence it is a true statement.
