I am in a tropical climate (12.8° N of the equator; 600m elevation). I am looking at cover crops that I can use, particularly those that will add biomass and nitrogen to my rocky clay soil.

Sunn Hemp (Crotalaria juncea) seems like a good candidate. Does anyone here have experience with it?

I also have what probably will seem like a weird question. How much does it look like marijuana? I ask because I live in Nicaragua and our President is very anti-drug. We also have a bunch of nosey neighbors around us. I am a resident here, not a citizen. The absolute last thing that I need is for one of my neighbors to see Sunn Hemp on my property, mistake it for marijuana, and report it to the police. Logic likely will not prevail with the police, especially if there is a resemblance to marijuana. I could potentially find myself in jail for an indeterminate amount of time and subsequently deported.

If this plant does indeed have a resemblance to marijuana, could anyone suggest alternative cover crops that I might try. Most of the available information applies to temperate climates in North America and Europe. I am not sure how the recommended plants will work in my area.

Thanks in advance.

Sun hemp has trifoliate (three) leaves not pinnate leaves, not palmately compound leaves, it is also a thinner plant.  That said, from a distance it might be mistaken.

Consider Velvet bean (Macuna sp.) & Lablab bean (Dolichos lablab)  hopefully you could get seed.  Sun hemp is sometimes preferable since Velvet bean and Lablab bean are vining.

Here is some addition information from Echo on cover crops:
