Monsoon winds can affect agriculture of course.
How? Influencing the pattern of rainfall.
Those countries affect by monsoon winds can see a significant difference in amount of rainfall received in dry season and wet season. For example is India. India is one of the most important country affect by monsoon according to my teacher haha.
I am too lazy to type down the specific steps of monsoon from my geography textbook so I would summarize:
When northeast monsoon comes to eg. India, it carry large amount of moisture from the ocean. Upon reaching land, it will fall as rain. Monsoon winds carry very large amount of moisture so amount of rainfall is greater than usual.
This may be good to agriculture and may not be It will be good because poor farmers can water their crops which the crops had been lacking for the past few months, no more droughts and subsequently no more famine. India farmers are saved. Worst case scenario for large rainfall is that it caused floods and destroy the crops. Crop failure then adversely affected the agriculture industry of India.
Ok another monsoon wind southwest monsoon, moisture is taken away from India. Rainfall is very little, that's why I mentioned above that there could be droughts and famine if northeast monsoon never follows. So it would mean that the crops would not grow pretty well and then industry affected blah blah blah.
I found this on https://www.stratfor.com/video/effects-monsoon-season-india-dispatch. I think it will be useful if u read this:
"The monsoon has two phases. The first carries moisture from the Arabian Sea up through the Indian subcontinent. It begins in June and covers most of India with rain until September. In late September, these winds reach the Himalayas and make an abrupt about-face. From late October to December, the monsoon glides back down over the subcontinent on its way to the Indian Ocean.
Agriculture accounts for 18 percent of India’s growth domestic product (GDP) and employs around half of its total workforce. The monsoon rains are the main source of water for 55 percent of the country’s arable land. This means the rains are crucial — not only for India’s farmers, but for its economy as a whole.
Now, that’s a good thing when the monsoon arrives on time and brings the right amount of rain. But when it’s late or weak, it leads to drought. When it’s too strong, it can trigger floods. The two-phase pattern of the winds defines Indian agriculture, so when the pattern shifts even slightly, it can have real implications for food production.
In the past, seasonal fluctuation was a matter of life or death for Indian farmers. A bad year meant widespread famine. Today, the situation is somewhat different. Most parts of India now have irrigation systems that farmers can turn to in an emergency, so even when rains are late or weak (as they have been this year), farmers have ways to supplement them."
