It depends, there are all sorts of reasons.
Volcanic soil is very fertile for example.
Also, valleys are formed by water running through then drying up. Valleys would have all the minerals from the water in it's soil, making it richer.
Most crops tend to perform the best in valleys, due to the more stable climate and topography. There are some crops that are still grown in their natural mountain habitat, such as trees for lumber and a US Pacific Northwest treat, huckleberries. But most of what we would consider usual crops will do best on relatively flat land with a temperate or warm climate.
Different crops require different growing conditions. In some areas, cereal crops (wheat, barley) grow well. Other areas may be better suited to the growing of oats, beans and root crops. The weather and the season, where the crop is to be grown (in the north of Scotland, or in the south of England, can make a huge difference), the soil constituency (loam, sandy, clay) also make growing some crops unsuitable in some areas.
Yes, Prince Edward Island (PEI) does have valleys. While not as prominent as in some other regions, PEI does have low-lying areas between hills and ridges that can be considered valleys. These valleys contribute to the island's diverse landscape.
The Philippines does not have valleys specifically defined like in some other countries. Instead, it has various landforms such as mountain ranges, plateaus, and plains. However, there are some valleys in the Philippines, such as the Cagayan Valley and the Pampanga River Valley.

It depends upon what is being grown. For example, the dry inner valleys of B.C. are the best place in Canada for growing grapes, and the prairies in Central Alberta, around Edmonton, are some of the most fertile in the country, making them excellent for cereal crops (such as wheat, rye, barley, etc.). Grapes would not grow well (if at all) in Central Alberta, as the winters are too cold, and the soils in the valleys of inner B.C. do not support cereal crops very well.
mountainous with valleys. some flat ares for rice growing
hydrophonics
Factors which will come in mind for growing some seeds are as follow:- => preparation of soil => sowing => manuring => irrigation of crops => weeding => protection of crops => harvesting => storage
biological
they didnt know how to grow crops
They probably cleared it
different ways of growing crops
No. Some crops can grow IN crops, such as with the use of nurse crops, or purposely mixing two different types of crops (like barley with oats) in one field, mainly for the purpose of growing livestock feed.
because it ensured that crops were growing all throughout the year.
For some crops the growing season is too short.
