Great input guys, thanks! Here's some detail of how/what I'm doing.
A little about our weather here first. We have two seasons, a dry one (summer) and a wet one (winter). Winter normally starts in May and runs through the end of the year.....though the months of June, July, and August normally give us the best rainfalls. Sept, Oct, in some years produces some decent water....Nov and December normally much less.
Summer is brutal. We sometimes go several months without a drop of rain......March/April being the worst.
My soils are mostly sandy loam and my land fairly hilly......drains/drys pretty fast. Having said that, Í've got soils in some of the 'lower' areas that are almost black and are very productive though trickier to work during the rainy season.
I'm working the ground with my Brazilian-made JD, 95 hp tractor and a 20 disc plow. When humid enough, the ground breaks up nicely and normally within 3 passes I've got a seedbed of fine powder. If the ground is very dry and/or hasn't been plowed for some time, it's obviously much more difficult to plow. I wish I had equpiment like a spring-toothed harrow we used in Louisiana in preparing seedbeds, but that sort of stuff just can't be found here, at least not in this part of the country.
I broadcast both my seed and my fertilizer using this gizmo:
I plant a certified seed (nationally-grown) at 20 kilos per hectar, broadcast. I wish I had photos of last year's operation when we covered the seed. We used what I called a Venezuelan rake.....a very large branch of an
arbol de aceite (oil tree), weighed down with fence posts and dragged behind the tractor. :lol:
This year I've really upgraded my seed covering technology by using a large, square frame of metal tubing with hurricane fencing attached.

It gets the job done and covers the seed better than the Venezuelan rake.
Based on what I've read on the internet, I try to have my nitrogen ready for the plants as they're reaching the 30 day point, which is when head development begins and there's a rapid uptake of nitrogen. If rainfall is right, I'll sometimes apply nitrogen in two applications but wasn't able to do so this year. I apply urea at a rate of 150 kilos per hectar.....same with fertilizer.
Fertilizer here is a crap-shoot....you buy what you can find, which is usually 10-20-20, sometimes 15-15-15. I think I've seen 0-20-20 as well but this year I found 10-20-20.
On one small area of sorghum this year (a section that was part of my failed planting but still had enough germination that I left it alone) I used a spray-on liguid fertilizer. I'm not sure how it's worked out yet. The plants have headed out and adjusting for the failure to cover the seeds, the production looks decent.
Here's some more pics for you guys to get an idea of what my process looks like.
