If you are wondering why I’ve been a little quiet lately, it’s because we’ve been busy cutting test plots and gathering harvest data.  After long days in this horrendous heat, it’s hard to find a desire to sit at a computer and write. This morning it was so dark outside that I tried to fool myself into think it was a nice, cold winter storm – no such luck. 
I’ll wait until all the numbers are in to make any comments about the effect of treatments on yields.  In the meantime, I thought you might like to see some equipment in action.  The best part of harvest is that it really is a gathering of friends.

Dean Reed (Helena), Sunny Bottoms (HorizonAg) and Vince Deshotel (LSU AgCenter) waiting in the shade near the weigh wagon. Charlie was busy trimming the edges so we could cut our passes.

 

The first step is to trim the edges of the field so that we are harvesting from a measurable area and can calculate accurate yields. 

Combine in the background is trimming the edges, and in the direct line of the camera you can see that the front edge has been trimmed to make a clean starting line for the pass.

 

The second step is to run a pass up the treated area. 

The combine is about to finish the first pass in the untreated area.

 

Along the way, the header is cutting the head (panicle) off the rice plant and separating the hull (containing the grain) from the straw.  The grains are collected in the hopper and the straw is ejected out the back of the combine.

After the pass is completed, the rice is transferred from the combine into the weigh wagon. 

Combine lined up with the weigh wagon to empty the rice out of the hopper and calculate the yield.

 

The weight, grain moisture, and temperature of grain are recorded.  Then the contents of the weigh wagon are emptied into a grain cart to get ready for the next round.

In the meantime, someone else has the physical job (which was tough in that extreme heat yesterday) of measuring the length of the harvested area.  This is measured with a wheel.  Dean Reed was walking the wheel in this picture.

This process is repeated until you complete the harvest.  

Birds are often attracted to the combine and are real daredevils as they dive and dodge for grasshoppers, frogs and other critters. 

Rice and soybean farmer Charlie Fontenot anticipates that he will be harvesting for more than 20 days straight to get all the rice cut and then roll into soybean harvest.  We thank him for participating in this variety trial and demonstration test.  The rice we harvested will be fertilized and flooded up for second crop.
