Rice plants.
Think GMO crops. Not natural selection, we selected them artificially
The agroecosystem can be viewed as a subset of the conventional ecosystem. Agroecosystem deals with the human activity of agriculture. Example a farm has an impact on the species assemblages and energy flows as well as the net nutrient balance.
yes there are crops grown in mud for example : cattails , Paddy etc
Crops need water, but they also need sunlight, so the best weather is a mixture of some rain and some warm sunny days. If you have nothing but sunlight, you may be able to irrigate the crops, in which case they will grow quite well, but not all farmers are able to do that (witness for example the current drought in north Africa).
Leguminous crops, such as peas and beans, fix Nitrogen from the air and make it available to plants. "Cover crops" - winter rye for example - planted on the land when it is fallow, and then "plowed under" later - also improve the fertility, if given a season to decompose.

Cash crops. Example: some of the earliest cash crops in North America were tobacco and cotton.
Zayed crops are crops which are grown between the Kharif and Rabi seasons. Examples: Watermelon, muskmelon, cucumber, vegetables and fodder crops.

Cotton Jute and Sissal and Hemp.
Cotton is also an example for kharif crops.
Canola, carthamus, groundnut and coconut etc.
The boll weevil ruined the cotton crops.
Derived demand comes from demand for another product. For example, if coal is in high demand, then there will be derived demand for mining. Another example: A farmer grows crops. In order to grow crops he needs fertilizer. Therefore, the amount of fertilizer he needs to buy, will derive from the amount of crops he needs to grow. Basically, derived demand comes as a result of demand for something else.
There are many ways in which farmers grow crops in Central Asia. These farmers could use terrace farming for example.
